3 How It Works

This chapter describes the various applications of the Combi unit series from COTEK.

The Combi unit is a battery charger, a pure sine wave inverter and an AC transfer system in one compact enclosure. The three-step Plus charging method guarantees that the batteries are always charged 100% The pure sine wave inverter assures that the AC output voltage is perfectly reliable even when limited external AC power is available. External AC power can be supplied by a public grid or a generator. DC power can be delivered by charged batteries.

3.1 Battery Charger Introduction

The built-in battery charger is electronically controlled. It is designed for optimal recharging of both wet cell, gel cell and AGM deep cycle batteries. Battery charging is accomplished in three automatic stages: BULK, ABSORPTION and FLOAT. With an external AC source connected, the Combi unit charger also serves the functions of an

AC to DC converter to supply DC loads which are connected to the battery. Simple, automatic operation is made possible by the microprocessor that is the brain of the inverter/charger Combination. In most cases, the unit is left on and no attention or maintenance is required.

Inverter / Charger COMBI

Fig 1: Three step charge system

3.1.1

Three step Plus charge system

See fig 1. The first step of the three step Plus charge system is the BULK phase, in which the output current of the charger is 100%, and the greater part of the capacity of the battery is rapidly charged. The current charges the batteries and gradually the voltage rises to the absorption voltage of 14.4V (12V models) or

28.8V (24V models) @ 25°C / 77°F.

The duration of this phase depends on the ration of battery to charger capacity, and naturally also on the degree to which the batteries were discharged to begin with.

The bulk phase is followed by the absorption phase. Absorption charging starts when the voltage on the batteries has reached 14.4V (12V models) / 28.8V (24V models) @ 25°C / 77°F, and ends when the battery is completely full. Battery voltage remains constant at 14.25V (12V models) / 28.5V (24V models) @ 25°C

/ 77°F throughout this stage, and the charge current depends on the degree to which the battery was initially discharged, the battery type, the ambient temperature, and so on. With a wet cell battery this stage lasts some four hours, with gel and AGM around three. Once the battery is 100% full, the charger automatically switches over to the float phase. (see Fig 12.)

During the float phase the Combi unit switches to 13.5V (12V models) or 27

(24V models) @ 25°C / 77°F and stabilizes this voltage to maintain the batteries in an optimum condition. Connected DC-loads are powered directly by the charger. If the load is higher than charger capacity, the required additional power comes from the battery, which will be progressively discharged until the charger

Inverter / Charger COMBI automatically switches back to the bulk phase. Once consumption decreases, the charger goes back to normal operation of the three-step charge system.

As the Combi unit is equipped with a three-step Plus charge system, the batteries can also remain connected to the Combi unit in winter. One hour every

12 days the charger automatically switches to absorption to keep the battery running properly and prolong its life span. The three-step Plus charge system is also safe for all the connected equipment.

3.1.2

Temperature compensated charging

The Combi unit is delivered with a battery temperature sensor. By installing this battery temperature sensor the charge voltages are automatically adapted for deviating temperatures.

Fig 2 : Temperature compensated charging

See fig 2. When the battery temperature is low, the charge voltage increases.

On the other hand, when the battery temperature is high, the charge voltage is decreased. Over charge and gassing are prevented this way. This will extend the life of your batteries.

3.1.3

Connection of a second battery

The Combi unit is equipped with second charge output which can be used to give a maintenance charge to a small battery set like a starter battery Maximum output current: 5 Amps.

Output voltage:14.4V @ 12V Model , 28.8V @ 24V Model , three-step, user can set ON or OFF.

Inverter / Charger COMBI

3.2 Inverter Introduction

3.2.1

General

The inverter provides voltage and frequency regulated AC power from a battery bank. Fast acting electronic circuits protect the inverter against extreme overloads, low and high battery voltage , overheating and short circuit of the inverter.

Considerable momentary surge power is available for starting-up electric motors.

A built in power saving feature can reduce battery power consumption when the inverter is unloaded.

3.2.2

Power saving mode (selectable)

In the inverter mode the Combi unit has a built-in automatic power saving feature that reduces battery power consumption when no load is present on the “INV.

AC output

”. Response from idle is instant, eight modes can be set by means of

DIP-switches or LCD remote control.

3.3 Operation Modes

The Combi unit is not just a Combination of an inverter and a battery charger. It has many additional features which can be used to increase the total available AC power, even when external AC power is limited.

3.3.1

Basic operation

When there is no external

“AC input” power available, the inverter of the Combi unit provides AC power on the “INV. AC output” output from the batteries. There is no AC power available on the “AC output”. See fig 3

12

Fig 3 : Inverter mode

When external AC power comes available, the transfer relay switches on. See fig

4. Both outputs as well as the battery charger are supplied by the external AC power. The batteries are recharged now.

Inverter / Charger COMBI

Fig 4 : Charger mode

3.3.2

Transfer Switch And Connector on The Front

The Combi unit has two AC-outputs available:

 INV. AC output: The “INV. AC output” output switches between the AC-input and the output of the inverter. The AC input has the highest priority. In principle, AC-power is always available on this output. However during a switchover the loads connected to this output are not supplied with ACpower for a very short period of time (short break). It is the ideal output for loads that need AC-power permanently like personal computers, interior lighting and the refrigerator.

 AC output: This output is always internally connected to the AC-input. It is therefore only available when an external AC-source like shore power, a generator or an outlet is present. Larger loads like a hot water boiler, electric cooking appliance or washing machine should be connected to this output .

See fig 5.

Fig 5 : AC Input / Output contact

13

Inverter / Charger COMBI

3.3.3

Power sharing function (selectable)

If the available power at the AC-input is limited, and the load connected to the

AC output increases, the external AC circuit breaker may trip if nothing is done.

To avoid this, the Combi unit can automatically reduce the battery charger output, and thus the AC power consumption. This Power sharing feature constantly senses the incoming AC current which is used to supply both the battery charger and the appliances connected to the AC outputs.

The Power Sharing level should be set to match the value of the external circuit breaker, which protects the incoming AC power. For instance, when the external

AC power is limited by a 10A circuit breaker or fuse, the Power Sharing level must be set to 10A.

14

Fig 6 : Power Sharing Function I

Here the Power Sharing level is set to a 10 Amps while the AC outputs consume a total of 2 + 5 = 7 Amps. This means that only 10

– 7 = 3 Amps is left over for charging. With 12V batteries 230 VAC this will result in a maximum charge current of approx. 45A DC.

The Power Sharing level can be set by means of the DIP-switches or LCD remote control locally on the Combi unit

When the total connected AC load reaches the level of the Power Sharing setting

(10A), there will be no power left over to charge the battery. This means that the charge current of the Combi unit will be reduced to 0A. See fig 7.

Inverter / Charger COMBI

Fig 7 : Power Sharing Function II

3.3.4

Generator function (selectable)

If the demand for AC power still increases, the external AC circuit breaker may still trip if nothing is done. This problem can be solved by the Generator function.

If the total demand for energy exceeds the maximum external power supply, energy can be added to the

“AC outputs” and “INV.AC Output” by means of the inverter. This appliance can be automatically connected in parallel with the external power supply.

Fig 8 : Generator Function

See fig 8. Here the AC-input is still limited to 10 Amps. This is not enough to supply the total load (6 + 11A = 17A) connected to the AC outputs.

When the Generator function is enabled, the inverter will supply the remaining

17

– 10 = 7A. This means that the restricted amount of external AC power will be compensated by energy which is stored in the batteries.

Later, when the AC load has dropped below the setting of the Power sharing

15

Inverter / Charger COMBI function again, the battery charger of the Combi unit will commence to recharge the batteries.

For safety unit the transfer relay is immediately switched off when incoming AC power fails in operation so that there will never be a high voltage on the shore cable inlet when it is not connected.

3.3.5

Support function (selectable)

As explained above, when the Generator function is enabled, the inverter will operate in parallel with the external AC power source. This means that energy from the batteries is added to the AC-output only. Under no circumstance AC power from the inverter can be fed back into the AC grid. This may mean that in some situations the use of the Generator / Support function is not allowed.

Please acquaint yourself with local regulations on this issue. Never use the

Generator function if this is not allowed!

Even if the use of the Generator function is not allowed, it is still possible to supply more energy than the external AC sourced can deliver This can be achieved by using the support function.

16

Fig 9: Support function

See fig 9. The AC input is still limited to 6Amps. This is not enough to supply the total load (6 + 9A = 15A) connected to the AC outputs.

Now when the support function is enabled, the transfer relay will open. When opened, the external power source will deliver 6Amps to supply the load conne cted to the “AC output” output only, while the inverter will deliver 9Amps for the load connected to the “INV. AC output” .

I f the power consumption of the “AC output” output exceeds the setting of the support function, the external AC fuse or circuit breaker will still trip

Inverter / Charger COMBI

3.3.6

Support and Generator function (selectable)

If user will support function and generator function both simultaneously enable.

The Combi unit inverter will operate in parallel with the external AC power source, and when not enough to supply the total load connected to the

“AC output

” and “INV. AC output”. The transfer relay will open.

Fig 10 : Generator and support function

See fig 10. The AC input is still limited to 6 Amps. If the demand for AC power still increases, the external AC circuit breaker may still trip. The inverter will automatically to compensated by energy which is stored in the batteries.

But when AC power still increases. This is not enough to the total load ( 7 + 9A =

16A ) connected to the AC outputs. The transfer relay will open.

3.3.7

Charger sharing (selectable)

The Combi unit used

“CHR.mode” startup. When external AC power comes available, the transfer relay switches ON. The Combi unit is constantly senses the AC power current witch is used to supply both the battery charger and the load Connected to the AC output.

Inverter / Charger COMBI

See fig 11. The AC input is still limited to 10Amps. Supply the total load ( 5 + 2A =

7A ) connected to the AC outputs. That only 10

– 7A = 3Amps is left over or sharing, if the AC outputs load increases more 10 Amps. The transfer relay will open.

When opened, the AC power will deliver 5 Amps to supply the load connected to the

“AC output” only. But the inverter not to supply 2Amps load connected to the

“INV. AC output”.

As explained above operation must will sharing function enable.

3.4 Equalization Batteries

3.4.1 Construction of Battery Cells: A Lead Acid battery consists of a number of 2 V nominal cells (actual voltage of the cell is 2.105 V) that are connected in series e.g. a

12 V nominal battery will have six, 2 V nominal cells in series (actual voltage of the 6 cells will be 2.105 x 6 = 12.63 V). Each 2 V nominal cell in this battery consists of an independent enclosed compartment that has Positive and Negative Plates (also called Electrodes) dipped in electrolyte that is composed of diluted Sulphuric Acid

– solution of 33.5% v/v Sulphuric Acid and water. In a fully charged battery, the

Positive Plate is in the form of Lead Dioxide, the Negative Plate is in the form of

Sponge Lead and the Sulphuric Acid in the electrolyte has the maximum concentration of 33.5% v/v .

3.4.2 Electrical power in the Lead Acid Battery is produced by reversible electro- chemical reactions as follows:

 During discharging, the Sulphuric Acid in the electrolyte reacts with the Positive and Negative plates resulting in conversion of the active materials in both the two plates (Lead Dioxide on the Positive plate and Sponge Lead on the Negative plate) to soft Lead Sulfate crystals. At the same time, electrons are released that create the electrical current that flows to the load. The concentration of Sulphuric

Acid in the electrolyte is reduced as the battery gets discharged (the electrolyte becomes pure water when the battery is fully discharged).

 During charging, reverse electrochemical reactions take place. Under the influence of the charging voltage fed to the battery by the external battery charger

/ charge controller, electrons are fed back to the battery and the soft Lead Sulfate crystals at the Positive and Negative Plates are converted back to Lead Dioxide at the Positive Plate and Sponge Lead at the Negative Plate and the concentration of Sulphuric Acid is restored (will revert to 33.5% v/v when the battery is fully charged).

3.4.3 Gassing during Charging:

During charging, the battery is required to be charged in a controlled manner in the final Absorption Stage (2.4 V per cell at 25 º C / 77 º F or

14.4 V for a 12 V battery at 25 º C / 77 º F) that restores the last 20% to 30% of the capacity. On successful completion of this stage of charging, the Lead Sulfate at the

Positive and Negative Plates should have fully converted back to Lead Dioxide at the

Positive Plate and Sponge Lead at the Negative Plate. Any further charging at this voltage or higher than this voltage results in electrolysis of water in the electrolyte to

Hydrogen and Oxygen and this undesirable condition contributes to waste of energy.

This process is known as "gassing". Gassing is also produced during the timed

Equalization Stage when the battery is intentionally overcharged (2.5 to 2.7 V per cell / 15 to 16 V for 12 V batteries) to equalize the cells and remove stratification.

3.4.4 Necessity for Equalizing Batteries:

For proper health and long life of a Lead Acid battery, it is required to undergo an Equalization Stage during the charging process to prevent / reduce the following undesirable effects:

 Sulfation: If the charging process is not complete due to the inability of the charger to provide the required voltage levels or if the battery is left uncharged for a long duration of time, the Lead Sulfate crystals on the Positive and Negative plates that are formed during discharging / self discharge are not fully converted back to Lead Dioxide on the Positive plate and Sponge Lead on the Negative plate and get hardened and are difficult to dislodge through normal charging.

These crystals are non conducting and hence, introduce increased internal resistance in the battery. This increased internal resistance introduces internal voltage drop during charging and discharging. Voltage drop during charging results in overheating and undercharging and formation of more Lead Sulfate crystals. Voltage drop on discharging results in overheating and excessive voltage drop in the terminal voltage of the battery. Overall, this results in poor performance of the battery. To dislodge these hardened Lead Sulfate crystals, some chargers are designed to detect a sulfated condition at the start of the charging process and go through an initial De-sulfation Mode that sends high frequency, high voltage pulses at the natural oscillation frequency of the crystals to dislodge the hardened crystals. Sulfation may also be reduced partially by the stirring / mixing action of the electrolyte due to gassing and bubbling because of intentional overcharging during the Equalization Stage.

3.4.5 Electrolyte Stratification: Electrolyte stratification can occur in all types of flooded batteries. As the battery is discharged and charged, the concentration of acid becomes higher at the bottom of the cell and becomes lower at the top of the cell.

The low acid concentration reduces capacity at the top of the plates, and the high acid concentration accelerates corrosion at the bottom of the plates and shortens the battery life. Stratification can be minimized by the Equalization Stage by raising the charging voltage so that the increased gassing and bubbling agitates / stirs the electrolyte and ensures that the electrolyte has uniform concentration from top to bottom. The stirring action also helps to break up any Lead Sulfate crystals, which may remain after normal charging.

3.4.6 Unequal charging of cells:

During normal charging, temperature and chemical imbalances prevent some cells from reaching full charge. As a battery is discharged, the cells with the lower voltage will be drained further than the cells at the higher voltage. When recharged, the cells with the higher voltage will be fully charged before the cells with the lower voltage. The more a battery is cycled, the more cell voltage separation takes place. In a healthy battery, all the individual cells will have the same voltage and same specific gravity. If there is a substantial difference in the

21

Inverter / Charger COMBI cell voltages (0.2 V or more) and in the specific gravities (0.015 or more) of the individual cells, the cells will require equalization. Equalizing batteries helps to bring all the cells of a battery to the same voltage. During the Equalization Stage, fully charged cells will dissipate the charging energy by gassing while incompletely charged cells continue to charge.

3.4.7 Equalization Stage: Normally, only the vented / wet cell / flooded batteries are equalized. Some sealed AGM batteries may be equalized if recommended by the manufacturer (e.g. Life Line brand of sealed, AGM batteries). The Equalization Stage is carried out only after completion of the Bulk and Absorption Stages. During the

Equalization Stage, the battery is intentionally held above the Gassing Voltage for a specified period of time that is normally proportional to the depth of discharge of the battery or to the AH capacity of the battery.

 Recommendations of the battery manufacturer are to be followed for equalizing the batteries as the equalization voltage, time and frequency will depend upon the specific design of the battery. The Equalization Voltage will normally be in the region of 2.5 to 2.7 V per cell at 25 º C / 77 º F e.g. 15 to 16 V for 12 V batteries and 30 to 32 V for 24 V batteries. As a guide, a heavily used flooded battery may need to be equalized once per month and a battery in light duty service, every two to four months.(See fig13)

*User can be setting the custom function voltage, but must use LCD Panel(See 6.4.4 for more information).

NOTE!

Gel and the AGM 2 Group (East Penn/ Deka

/Discover/Trojan brand) batteries are not equalized.

Hence, their Equalization Voltages are same as the

Absorption Voltages

When using the Custom setting, the Equalization voltage setting should not allow voltage lower than the Absorption Voltage setting. Also, the

Equalization Voltage setting should not allow a setting higher than 2-volts (for

12V systems), or 4-volts (for 24V systems) above the Absorb Voltage setting.

3.4.9 Calculation of Equalization Charge Current: The Equalization Charge Current should be a relatively low current of around 1% of the charge current of the battery.

Such a low current prevents an overcharge condition that results in excessive gassing and excessive loss of water. Also the equalization charge current should preferably be a variable value that is automatically set by the microcontroller as a function of the degree of charge of the battery.

NOTE!

Equalization Current is related to the charge current capacity of the battery and is normally calculated at 1% of the charge current of the battery.

Hence, We has provided for the user to input the charge current capacity of the battery being used.(See 6.4.4)

3.4.10 Calculation of Absorption and Equalization Times: Equalization is required to be carried out after completion of the Bulk and Absorption Stages. It is preferred that the time periods for the Absorption and Equalization Stages be proportional to the discharged state of the battery. A more discharged battery will take longer time in the

Absorption and Equalization Stages. The discharged state of the battery will be proportional to the time the charger remains in the Bulk Stage. Hence, a software timer may be used to measure the time the charger is in the Bulk Stage and then calculate and set the Absorption Stage and Equalization Stage Timers. Let the time

23

Inverter / Charger COMBI taken in the Bulk Stage be designated by “Bulk Timer” and the calculated Absorption

Time by “Absorption Timer and the Equalization time by “Equalization Timer”

.

One of the recommended logics for calculations is as follows(See Fig 13):

 Absorption Timer

= 0.5 x Bulk Timer

 Equalization Timer

= Absorption Timer + 1 Hour if T

1

< 2 Hours, or

 Equalization Timer

= Absorption Timer + 2 Hours if 2< T

1

< 4 Hours, or

 Equalization Timer

= Absorption Timer + 4 Hours if T

> 4 Hours

5.2.6 DC Input Connection: (reference

⑥)

Follow the instructions to connect the battery cables to the DC input terminals of the Combi unit. The cables should be as short as possible (less than 6 feet / 1.8 meters ideally) so that they can handle the required current in accordance with the Electrical Codes and Regulations. The size of the cable should be thick enough to limit the voltage drop to less than 2% when carrying the maximum input current to prevent frequent low-input voltage warnings, and shutdown. UVP

(Under Voltage Protection) warning may result if there is excessive voltage drop across the DC cables between the batteries and the Combi unit. Increasing your

DC cable size will help improve the situation.

Batteries are capable of providing very large currents in case of short circuit. In case there is a short circuit in the cable run between the batteries and the input terminals of the Combi unit, it will result in overheating / melting of the cables and consequent risk of fire and injury, To prevent possibility of this hazard, use

Very Fast Acting DC Fuse in line with the positive cable. The fuse should be as close to the positive battery terminal as possible. Use Busman ANN series fuses

( will also require Fuse Block 4164) or equivalent.

The following sizes of cables and fuses are recommended for up to 6 ft. distance between the batteries and the Combi unit. (Applies to both 120 VAC and 230
