Battery Management System


The battery management system detects remaining battery capacity in electric or hybrid vehicles with a high degree of accuracy, performing a variety of battery-related monitoring and control functions such as charge and discharge control, cell balance control, high-voltage line connection control, and cooling control.

The Keihin Advantage

Compact, lightweight, low profile
The upper cover uses a compact, lightweight, low-profile resin housing to make the system resistant to high temperatures and vibration as well as adapted to electromagnetic environments, while also improving efficiency in electric vehicles.

Unique design maximizes battery charge capacity
The single-body resin construction with built-in cell voltage sensor functionality is designed to improve cell voltage detection accuracy, offering more flexibility in mounting angle options for the battery-monitoring IC.This in turn increases battery charge capacity.

Conforms to ISO26262 ASIL-D
The highly-reliable design conforms to functional safety standard ISO26262 ASIL-D and prevents cell overcharging.

Reliable EMC design
The EMC-tested design reduces the generation of electrical noise while also protecting the unit from outside electrical noise.
