Battery Monitoring Unit
The battery monitoring unit detects voltages and current of the main battery in hybrid electric vehicles (HEVs) and calculates the main battery’s state of charge (SOC). This maintains an appropriate SOC and prevents over-charge or over-discharge of the main battery.
The battery monitoring unit also detects:
- main battery abnormalities
- degree of deterioration
- accidental electrical connection between the high-voltage part and the body
DENSO provides high quality battery ECUs for nickel metal hydride batteries as well as lithium ion batteries.
- Quick and precise voltage detection
- Small size and light weight
