In applications where the battery is very intensively used, as is the case with city buses and coaches, continuous monitoring of the battery parameters voltage, current and temperature is crucial in order to prevent failures. The Intelligent Battery Sensor (IBS) from HELLA does just that. The IBS is attached directly to the negative terminal of the battery using a pole terminal. Additional mechanical components of the sensor include the shunt and ground bolt. The shunt is attached to the vehicle’s load path and is used as a measuring resistor to measure the current indirectly. The existing ground cable can be conveniently attached to the ground bolt, using the optional battery pole adapter for example. The electronics are housed in a potted housing. In this case, a plug connector acts as the interface for vehicle-internal energy management. Communication with the higher-level control unit takes place via the LIN protocol. The supply voltage is provided by the connection to the positive pole of the battery. This also serves as the reference voltage for voltage measurement.
Efficiently plan the vehicle energy supply: This is possible with the Intelligent Battery Sensor (IBS) from HELLA which delivers information to the user about the current status of the energy balance at any time. The IBS makes a significant contribution towards avoiding vehicle breakdowns due to poor battery performance by continuously and reliably monitoring the charge state, ageing and other parameters. The IBS is integrated into the vehicle electrical system so the energy management can quickly respond if the battery condition is critical. This allows the alternator as well as consumer behavior, which frequently has an underlying effect on battery performance, to be positively influenced and the risk of a vehicle breakdown due to the battery to be minimized. The IBS also supports other vehicle functions such as the automatic start/stop system or the intelligent alternator control. CO2 emissions can also be reduced by optimizing the alternator control system which in turn reduces the impact on the environment. Owing to the carefully thought out and compact design of the Intelligent Battery Sensor, it can be flexibly integrated into many different vehicle environments. This reduces the number of variants.
