Solutions
Battery Management System (BMS)
The energy storage system, which includes the battery management system, stores and supplies electric power for all vehicle needs. This system needs protection from a wide range of electrical threats, such as high fault currents, voltage transients, overcurrent, and overloads. Each threat is best countered with the right type of circuit protection technology.
Inside the battery pack is a number of battery modules made up of individual battery cells. This architecture dictates that layers of circuit protection are required. At the module level, the battery module and cable should be protected from overcurrent and from overloads between power-sense lines. The electronics should be defended against voltage transients, and the CAN (Controller Area Network) and other communication buses should be safeguarded from ESD and voltage transients.
Battery Module
Hybrid and electric vehicle batteries can be recharged from standard power outlets by using an AC-DC converter system or directly from DC power that is covered outside of the vehicle for faster charging. Design challenges include protecting against overcurrent, overvoltage, and ESD, as well as controlling switching of the input rectifiers. Littelfuse offers a broad range of High-voltage Fuses, Varistors, GDTs, Switching Thyristors, TVS Diodes, and TVS Diode Arrays to address these threats.
On-Board Battery Charger
The traction motor inverter changes DC current from the battery into the AC current needed to drive the traction motor of an electric or hybrid electric vehicle. Littelfuse offers a variety of components across this system, such as a fuse on the power supply and thermal protection on the motor.

Mechanical/hydraulic actuators are replaced with electric motors, such as those for electric parking, braking, seat modules, and mirrors. Solenoid valves are used to control fluid flow of water, air, and oil. Potential threats include load dump, overcurrent, surges, and ESD. Littelfuse offers a wide range of TVS Diodes and
TVS Diode Arrays, MLVs, MOVs, and PPTCs to protect motor and valve control applications.
Motor and Valve Control
Vehicle Electric/Electronic (E/E) Architecture is migrating from distributed through domain-centralized toward zonal architecture enabling the Software-Defined-Vehicle and other system level benefits.
Zonal Control Unit
A battery distribution unit is like the vehicle’s junction/panel box, delivering power to the many systems that need it. In electric vehicles, the unit relies on high-current, high-voltage fuses and contactors. Drawing upon its deep experience in the automotive industry, Littelfuse provides both fuses and contactors that are reliable and safe for this emerging application.
Battery Distribution Unit
The DC–DC converter changes the high voltage from the battery to a lower level of voltage, which is needed by a wide range of onboard systems: 12 V loads, including lighting, sensors, and entertainment, and 48 V loads, including heating, powertrain, and air conditioning. Littelfuse IGBT Gate Drivers control the switching MOSFETs for energy-efficient power conversion. Power semiconductor devices are vulnerable to electrical threats, which is why circuit protection is particularly important.
DC-DC Converter
Littelfuse New Current Sensing Resistor family for automotive and consumer electronics markets provides overcurrent protection, current monitoring, and control of critical electronics.
