Bosch Electronic Battery Sensor

[Stephen Waugh]

Bosch's Electronic Battery Sensor (EBS) helps in avoiding the most common cause of breakdowns - a flat battery. With its integrated evaluation electronics, the sensor measures the battery voltage, current, and temperature, calculating from these all the information that describes the condition of the car battery. The energy management system incorporated in modern cars uses these values to continuously guarantee sufficient battery energy, so that the vehicle can be started reliably even after a long stationary period. The Bosch EBS consists of a chip that contains all the electronics and a shunt for current measurement. These two components along with the pole terminal form a unit that can be connected directly to the car battery as they fit into the pole niche of standard automotive batteries. This yields to significant savings in both space and costs over solutions used hitherto.
