130-g/km (and future planned 95-g/km)
CO2 average emission limits for car manufacturers in Europe are also catalysts behind new electrified transportation alternatives. With the adoption of more electronics, vehicles become safer, exhibit higher performance, and are more efficient.
Electric transportation is a key element within the overall renewable energy landscape. Energy for charging is expected to come from renewable sources like wind-, solar- or waterpowered plants. Home and public charging stations will also become more prevalent and can take advantage of off-peak charging (nighttime) and green energy sources such as wind.

Introduction to the guide
This Hybrid and Electric Vehicle
Solutions Guide is intended to help you explore TI’s IC solutions as the various transportation sectors become increasingly electrified on a path toward energy efficiency and sustainability. This guide features several system block diagrams, followed by details about key devices and support functions.
System Architecture of HEV/EV
The hybrid and electric vehicle system is built of several modules to form the drive train and energy storage system. The battery block (typically a
Li-ion chemistry in the range of 400
V) is managed and monitored by the battery management system (BMS) and charged via an on-board AC/
DC converter module, with voltages ranging from 110-V single-phase to
380-V three-phase systems. The DC/
AC inverter uses the high voltage of the battery to drive the electric motor, but also is used for regenerative breaking, storing energy back into the battery.
To connect the high-voltage battery to the conventional 12-V board net requires a DC/DC converter. The connection of a high-voltage battery to the inverter also requires a reversible
DC/DC converter in most cases. The complete HEV system has to meet specific safety requirements (up to
ASIL-D) that are specifically relevant for managing the high-voltage battery pack, as well as the drive train used for breaking.

Battery Management
Introduction to Battery Management
Plug-in hybrid electric vehicles (PHEVs) and battery electric vehicles (BEVs) are two quickly emerging technologies that use powerful electric motors as the propulsion source. In order to power these electric motors, large battery packs are made up of hundreds of cells, totaling 300-400 V installed in the vehicle.
Because batteries have a finite energy capacity, PHEVs and BEVs must be recharged on a periodic basis, typically by connecting to the power grid. The charging system for these vehicles consists of an AC/DC rectifier to generate a DC voltage from the AC line, followed by a DC/DC converter to generate the DC voltage required by the battery pack. Additionally, advanced charging systems might also communicate with the power grid using power line communication (PLC) modems to adjust charging based on power grid conditions. The battery pack must also be carefully monitored during operation and charging in order to maximize energy usage and prolong battery life.
High-performance analog parts are also available to provide critical system functions and features such as sensor feedback, isolation, chip power supplies and communication transceivers.

Battery Management Systems
The bq76PL536A family of voltage and temperature monitors and balancers is designed for high-cell-count battery packs. They can handle the voltages and currents found in high-power applications like electronic mobility.
The more cells a pack has in a series, the greater the difference in state of charge, impedance, and capacity affecting the health and energy delivery of the pack. The bq76PL536A device includes circuitry for bringing the cells back into balance. This increases the lifetime of the pack and can help deliver as much energy to the application as possible. Each bq76PL536A device protects from overcharge, over discharge, and over-temperature for pack and system safety.

BMS is a key element in the overall
HEV architecture. Not only will an intelligent implementation extend the battery’s lifetime, but it can also extend the possible range of the vehicle in fully electric drive mode, which is a key selling point to end users.
The battery system is often divided into several submodules that can be placed in various positions in the vehicle. All of these modules require battery supervision and battery cell-balancing features, often connected through different communication paths to ensure system redundancy. Built-in temperature management is also a crucial element for the system lifetime, and for safety.
The complete battery system represents a highly safety-critical function; therefore, the microcontroller needs to meet specific safety requirements.

Battery Management: Applications
bq76PL536A-Q1 Stackable Monitor, Protector and Balancer for Three- to Six-Series Li-Ion Cells
The bq76PL536A is a stackable, three- to six-series cell lithium-ion battery pack protector and analog front end (AFE) that incorporates a precision analog-to-digital converter (ADC), independent cell voltage and temperature protection, cell balancing, and a precision 5-V low dropout regulator (LDO) to power user circuitry.
The bq76PL536A provides full protection (secondary protection) for overvoltage, undervoltage and overtemperature conditions. When safety thresholds are exceeded, the bq76PL536A sets the fault output. No external components are needed to configure or enable the protection features.
Cell voltage and temperature protection functions are independent of the ADC.
The bq76PL536A is intended to be used with a host controller to maximize the functionality of the battery management system. However, the protection functions do not require a host controller. The bq76PL536A can be stacked vertically to monitor as many as 192 cells without additional isolation components between ICs.

Power Conversion Systems
DC/DC Converter Using C2000™ Piccolo™ MCUs
In automotive solutions, a bidirectional DC/DC converter is useful in many applications. For example, on the high-voltage side, an H-bridge topology is used to drive an inverter for the electric motor. When the driver steps on the brake, an H-bridge on the secondary side can use the back electromotoric force (EMF) to recharge the battery.
Alternatively, a bidirectional DC/DC converter can be used in systems that have both a high-voltage lithium-ion battery and an automotive
12-V battery to add more capabilities, as well as increase flexibility.

Charging and Charging Infrastructure
Introduction to Charging and Charging Infrastructure
The charging infrastructure connects the car to the smart power grid. The cost for the individual charging spot has to be balanced with the additional expansion capabilities on the communication side. The obvious choice for communication is a wired system via the charging cable, where power line communication is a widely used method. In that area, several activities for standardization are ongoing at the utilities side.
Texas Instruments is actively involved in standards development and offers solutions for SFSK and narrowband
OFDM systems for the CENELEC A and B band, with OFDM standards like
PRIME/G3.
The TMS320F28x microcontroller family is a flexible platform meeting these standards, with reference designs available.
Other options like RF communication using ZigBee or ISM band solutions are available, as are RFID systems for customer identification and prepayment options at the charging spot. The metering function for single-phase up to complex three-phase solutions can be realized with single-chip solutions out of the MSP430™ MCU family.

Charging and Charging Infrastructure
Charger Systems – AC Levels 1 and 2 (Onboard)
Since batteries have a finite energy capacity, PHEVs and BEVs must be recharged on a periodic basis, typically by connecting to the power grid in some form. For most users, Level 1 charging (120 VAC at 15 A-20 A) will be the most available power supply that all onboard chargers should be capable of handing, as it will be easily accessible to all users. In its current state, most users would prefer to take advantage of the faster charging Level 2 (240
VAC at 40 A) that will allow for faster charging times compared to the
Level 1, but will require a larger power source to supply the appropriate current and voltage. By having the capacity to handle both types of charging, you provide users with more flexibility in their charging options and a larger number of locations where a charge can be delivered.
The Level 1 and 2 charging system for these vehicles consists of an AC/
DC converter to generate a DC voltage from the AC line. This incoming power needs to undergo power factor correction (PFC) to boost the power factor to meet regional regulatory standards.
At the heart of the inverter is a real-time
C2000™ microcontroller. This controller is programmed to perform the control loops for all necessary power management functions, including AC/
DC with PFC and DC/DC to create the necessary charge profile for the battery. The C2000 controller contains advanced peripherals such as highprecision PWM outputs and ADCs, and is designed to read the ADC and adjust the PWM within a single clock cycle, making real-time control possible.

Charger Systems – DC Level 3 (Offboard)
Level 3 charging will play a key role in the public charging area in order to reduce charging time and make it more feasible for users to benefit from on-the-go charging.
The Level 3 charging system for these vehicles consists of an AC/DC converter to generate a DC voltage from the
AC line. This incoming power needs to undergo power factor correction (PFC) to meet regional regulatory standards.
At the heart of the inverter is a real-time
C2000™ microcontroller. This controller is programmed to perform the control loops for all necessary power management functions, including AC/
DC with PFC and DC/DC to create the necessary charge profile for the battery. The C2000 controller contains advanced peripherals such as high- precision PWM outputs and ADCs, and is designed to read the ADC and adjust the PWM within a single clock cycle, making real-time control possible.
Communications on a simple system can be handled by a single processor.
More elaborate systems with complex displays and online billing/reporting, such as Level 3 charging, may require a secondary controller. Implementing a low-frequency narrow-band PLC (LF
NB PLC) solution provides an optimal fit in terms of bandwidth, power and cost requirements. Operating in the narrowband domain (frequencies up to 500 kHz) ensures data integrity while minimizing system cost. In doing so, this standard would leverage the existing power line infrastructure and provide a cost-effective means of integrating intelligent monitoring and control into new automotive systems.
Data rates can vary from 1.2 Kbps up to hundreds of Kbps based on the existing standards.

Charging and Charging Infrastructure
AC/DC Converter with PFC Using C2000™ Piccolo™ MCUs
The charging of the HEV/EV via the main grid demands a flexible setup to meet the various voltage levels in single-phase (120 V, 230 V) and three-phase 380-V systems with different current levels (16 A to 63 A). The charging time is certainly an important feature for the car’s end customer, but has to be balanced with the long-term aging behavior of the battery pack.
The AC/DC charging system shown offers a power factor control (PFC) function along with high-voltage power conversion to directly generate the battery’s DC charging voltage. An optional power line communication
(PLC) to communicate with the charging infrastructure can be implemented as well. This setup demands a high number of pulse-width modulation and analog-to-digital converter channels, along with powerful CPU performance.

Power Factor Correction with UCC
UCC28070-Q1 Two-Phase Interleaved Constant-Current-Mode (CCM) Power Factor
The UCC28070-Q1 is an advanced PFC device that integrates two pulse-width modulators (PWMs) operating 180 degrees out of phase. This interleaved PWM operation generates substantial reduction in the input and output ripple currents, and the conducted EMI filtering becomes easier and less expensive. A significantly improved multiplier design provides a shared current reference to two independent current amplifiers, ensuring matched average current-mode control in both PWM outputs while maintaining a stable, low-distortion sinusoidal input line current.
The UCC28070-Q1 contains multiple innovations, including current synthesis and quantized voltage feed-forward correction to promote performance enhancements in PF, efficiency, THD and transient response. Features including frequency dithering, clock synchronization and slew-rate enhancement further expand the potential performance.
The UCC28070-Q1 also contains a variety of protection features, including output overvoltage detection, programmable peak-current limit, undervoltage lockout and open-loop protection.

Motor Control
Introduction to Motor Control and Drive
The inverter will drive the electric motor for fully electric operation in full hybrids and EVs as well as for torque assist in a mild hybrid car concept. This can be done with a single motor positioned to drive one axis, but also using in-wheel motors to individually drive each wheel of the car. The microcontroller used may be required to meet strict safety requirements/standards, as not only the driving but also recuperative braking is controlled through this unit. In addition, the PWM’s output signals and sensing inputs have to be controlled, still embedded in the overall safety concept. Like with any other element in the HEV/EV space, isolation is especially important in the inverter module. Learn more about motor drive and control solutions from Texas

Introduction to Functional Safety
TMS570 Built-In SIL3 Certified Safety Concept
The TMS570 family is specifically designed to meet IEC61508 SIL3 for safety critical applications like HEV/
EV. A SIL3 certificate and the required documentation are available. A dual
CPU lockstep architecture simplifies development while eliminating redundant system requirements to reduce cost. CPU hardware built-in self test
(BIST) detects latent defects without complex safety drivers or code size overhead. Hardware comparison of
CPU outputs provides exceptional safety response time without additional software overhead. An enhanced ECC logic is integrated in the CPU to protect both memories and buses. All memories can be tested using hardware
BIST for high diagnostic coverage and an integrated memory protection unit
(MPU) protects against deterministic errors in application software.

Start/Stop Function
Introduction to Start/Stop
A start/stop system automatically shuts down and restarts an automobile’s internal combustion engine to reduce the amount of time the engine spends idling, thereby improving fuel economy.
This is most advantageous for vehicles that spend significant amounts of time waiting at traffic lights or that frequently come to a stop in traffic jams.
This feature is present in hybrid electric vehicles, but has also appeared in vehicles that lack a hybrid electric powertrain. For nonelectric vehicles
(called micro hybrids), fuel economy gains from this technology are typically in the range of 5 to 10 percent.
But because automobile accessories like air conditioners and water pumps have typically been designed to run off a serpentine belt on the engine, these systems must be redesigned to function properly when the engine is turned off. Typically, an electric motor is used to power these devices instead.
Power Management for Start/Stop Function
More and more modules inside a car have to be defended from voltage drop during cranking. This problem has increased with the implementation of start/stop (micro hybrid) systems, a trend seen in the automotive industry to improve fuel efficiency.
TI offers a variety of products in the power management area that can solve this system/customer problem.

Start/Stop Function
Start/Stop Function Using the C2000™ Piccolo™ MCU
Using a C2000™ MCU with enhanced real-time features brings both highspeed loop control and system management capabilities in a single device. The Piccolo MCU’s mathefficient CPU, closely coupled with high-performance pulse-width modulators (PWMs) and ADCs, can control multiphase boost stages over a wide range of operating points. Digital control schemes with feed-forward, three-pole/three-zero compensators,
PID, etc., allows power designers to realize complex and flexible loop control strategies that can be adaptive and managed for efficiency, transient performance, light-load operation, fault handling and rich diagnostics.
Independent control of each phase allows for current balancing within each phase, spreading the load evenly and improving reliability. This also adds phase-shedding capability, where at light loads one or two phases are used, hence increasing efficiency.
Under these conditions, “intelligent” management software can retune control loops by dynamically changing compensator coefficients. The above diagram shows a four-phase boost implementation where each MOSFET is controlled with a high-resolution PWM capable of 150-pS edge-placement accuracy, ensuring smooth PWM switching speeds from 100 KHz to beyond 500 KHz without the undesirable limit-cycle oscillations often associated with low-resolution PWMs.

Introduction to TI Isolation Products
The problem
• No endurance – existing isolation devices have a life expectancy of only seven to 10 years
• No high speed or precision – existing isolation devices – low speed, high skew, high jitter and high pulse distortion
• No high temp – existing isolation devices cannot operate at 150 Mbps at 125°C. Only a few can operate at >100°C at any speed
• Low EMI immunity – existing high-speed isolators are susceptible to EMI interference
The solution
• The TI integrated SiO2 isolation barrier technology provides the fastest, highest precision, highest temperature, high
EMI immunity and longest life solution

ISO722X Dual-Channel, 25-Mbps Digital Isolator
The ISO7220 and ISO7221 are dual-channel digital isolators. To facilitate PCB layout, the channels are oriented in the same direction in the ISO7220 and in opposite directions in the ISO7221. These devices have a logic input and output buffer separated by TI’s silicon-dioxide (SiO2) isolation barrier, providing galvanic isolation of up to 4,000 V. Used in conjunction with isolated power supplies, these devices block high voltage, isolate grounds and prevent noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry.
A binary input signal is conditioned, translated to a balanced signal, then differentiated by the capacitive isolation barrier. Across the isolation barrier, a differential comparator receives the logic transition information, then sets or resets a flip-flop and the output circuit accordingly. A periodic update pulse is sent across the barrier to ensure the proper DC level of the output. If this DC refresh pulse is not received every 4 µs, the input is assumed to be unpowered or not being actively driven, and the failsafe circuit drives the output to a logic high state.
The small capacitance and resulting time constant provide fast operation, with signaling rates available from 0 Mbps (DC) to 25 Mbps. The signaling rate of a line is the number of voltage transitions that are made per second expressed in the unit’s BPS (bits per second). The A-option and C-option devices have TTL input thresholds and a noise filter at the input that prevents transient pulses from being passed to the output of the device.

SN6501 Transformer Driver for Isolated Power Supplies
The SN6501 is a monolithic oscillator/power-driver, specifically designed for small form factor, isolated power supplies in isolated interface applications. It drives a low-profile, center-tapped transformer primary from a 3.3 V or 5 V DC power supply. The secondary can be wound to provide any isolated voltage based on transformer turns ratio.
The SN6501 consists of an oscillator followed by a gate drive circuit that provides the complementary output signals to drive the ground referenced N-channel power switches. The internal logic ensures break-before-make action between the two switches.

AMC1204-Q1 1-Bit, 20 MHz, Second-Order, Isolated Delta-Sigma Modulator
The AMC1204-Q1 is a 1-bit digital output, isolated delta-sigma (Δ
Σ) modulators that can be clocked at up to 20 MHz. The digital isolation of the modulator output is provided by a silicon dioxide (SiO2) barrier that is highly resistant to magnetic interference. This barrier has been certified to provide basic galvanic isolation of up to 4250 VPEAK according to UL1577, IEC60747-5-2, and CSA standards or specifications.
The AMC1204-Q1 provides a single-chip solution for measuring the small signal of a shunt resistor across an isolated barrier. These types of resistors are typically used to sense currents in motor control inverters, green energy generation systems, and other industrial applications. The AMC1204-Q1 differential inputs easily connect to the shunt resistor or other low-level signal sources. An internal reference eliminates the need for external components. When used with an appropriate external digital filter, an effective number of bits (ENOB) of 14 is achieved at a data rate of 78 kSPS.
