Sales request contact Brad Brodie

"The battery electronic control unit (ECU) detects voltages and current of the main battery in hybrid electric vehicles (HEV) and calculates the main battery’s state of charge (SOC) to: - Maintain an appropriate SOC - Prevent over-charge and over-discharge of the main battery The battery ECU also detects: - Main battery abnormalities - Degree of the main battery deterioration - Accidental electrical connection between the high-voltage part and the body DENSO provides battery ECUs for nickel metal hydride batteries as well as lithium ion batteries.


Benefits and Features - Quick and precise voltage detection: In 2003, DENSO developed a new voltage detection circuit that more quickly and precisely detects voltages than a conventional circuit, while maintaining the insulating property between the high-voltage and low-voltage sides in the battery ECU. Compared to a conventional circuit, DENSO achieved an approximately 50 percent reduction in voltage detection time and voltage detection error. - Small size and light weight: The newly developed voltage detection circuit has a simple structure composed only of switching elements and condensers, significantly reducing the size and weight of the battery ECU."
