Battery Current Sensors

The New Necessity of Battery Maintenance

As the electrical systems on newer vehicles continue to advance, battery maintenance has become an essential component to keeping vehicles on the road. Battery Current Sensor (BCS) components, which measure the charge and discharge current flowing through the battery, are critical for maintaining a healthy battery.

  • High-quality components accurately measure the battery's charge and discharge

Functions

  • Adjusts alternator output to improve fuel economy, increase energy system availability, and extend battery life by 10-20%

  • Identifies battery parameters such as state-of-charge, state-of-function, and state-of-health

  • Monitors the key-off current, which helps detect defective electronic components

 

Signs of Failure

When the battery current sensor fails, the vehicle will not charge correctly, leading to a DTC or a dead battery. Common signs of failure include:

  • Irregular charging rates

  • Low battery voltage

  • Corrosion on the battery or sensor connection

  • Broken or bare sensor cabling
