LITHIUM-ION BATTERIES
ARE THEY RIGHT FOR YOUR INDUSTRIAL APPLICATION?
Lithium-Ion (Li-Ion) battery technology has emerged as a challenger to traditional lead-acid batteries in industrial
applications. Which battery makes sense for you? It depends on your application.

WHAT ARE LITHIUM-ION
BATTERIES?
2
A family of battery technologies
that use Li-Ions to store energy
Sealed batteries that retain
their charge capacity for
thousands of complete
charge and discharge cycles1
Lightweight, rechargeable,
high energy density batteries
////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
HOW DOES LITHIUM-ION STACK
UP AGAINST LEAD-ACID?
$
Four times lighter and
three times smaller
Higher power
capability
Tolerates high shock &
vibration environments
No maintenance
Longer run times
Higher cycle life
Can be left partially
discharged
Fast charge capable
Possibility of thermal
runaway
Higher initial cost
(4-5x more)
BMS
Requires a battery
management system
(BMS)
Safety depends on
good pack design
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
Prices should continue to drop with maufacturing economies of scales and incremental
technologies improvements. Li-Ion is currently 4-5x more expensive than lead-acid
but has a better total cost of ownership (TCO) in some applications.
PROMISING

The level of quality and safety of a Li-Ion battery depends on its manufacturer
CELL QUALITY
PACK INTEGRATION
Not all Li-Ion batteries
are equal. The cathode
material used in Li-Ion
batteries gives them
their unique
temperament. High
quality, low variability
manufacturing controls
must be used for cell
assembly
A holistic risk
management approach
to the battery pack will
design in safety at
every level of
integration. Consider
cooling, interconnects,
electrical insulation
and packaging
BATTERY MANAGEMENT
SYSTEM (BMS)
SAFE AND SMART
CHARGER
Use and approve a BMS
that can disconnect the
cells or stop their
charge/discharge
By choosing a flexible
charger, you will have
the ability to use the
same charger even if the
battery type changes
(lead-acid to Li-Ion)
BMS
Delta-Q’s IC Series Industrial Battery
Chargers are capable of charging both
lead-acid and Li-Ion battery packs. Delta-Q
works with major battery manufacturers to
ensure safe operation of the battery and
charger systems. Additional capabilities
include support for CAN bus communication
and customizable charging algorithms for
motive applications.
= A SAFER OVERALL SYSTEM
Consists of well made cells, a battery management system, and
an intelligent charger. How do you do that? See below.
BATTERY MANAGEMENT SYSTEM (BMS)
Functions of a BMS
1.
An electronic system that prevents Li-Ion batteries from going outside their safe operating
conditions and, in the worse case, experiencing thermal runaway.
Measure
Pack current and voltage, every cell
voltage, and subset of cell temperatures
2.
BMS
2.
3.
3.
Monitor
For over-voltage, under-voltage,
over-temperature, and over-current
2.
2.
“
Control
Balance cell state of charge, sends
power and current limits to the
machine, and derate or shut down
the battery pack if needed
An appropriately designed
BMS is a necessity when
lithium-ion is involved.

HOW TO SELECT A LITHIUM-ION CHARGER?
1
2
3
IC Series
Charger
Pick a charger as reliable as your batteries
Sealed, ruggedized chargers will survive.
Pick a charger that will accurately recharge the batteries
B+
Voltage accuracy means you always get to 100% charge.
Control accuracy means the charger responds
appropriately to given commands.
B-
BMS
Pick a charger as smart as your batteries
Batteries are getting smarter with integration of CAN bus,
USB, Modbus, and more. A charger that can connect to a
BMS will form a robust system. Working together, the
charger and BMS will keep you informed on your
machine’s performance.
