Charged EVs | Continental launches new sensor programs for EV battery safety


Components provider Continental will provide two new sensor programs for safeguarding EV batteries.

The Present Sensor Module (CSM) is designed to guard batteries from over-currents by monitoring present and temperature. The ASIL D-compliant module additionally assists in calculating vary by monitoring the present consumed and aids to find mechanical malfunctions.

The corporate says, “To assist strict practical security necessities, the CSM is offered as a two-channel sensor, measuring present independently by integrating shunt expertise and corridor expertise in a compact, single unit.” It offers knowledge to the BMS via a CAN interface.

The CSM will be built-in right into a battery disconnect unit or a battery and will be calibrated as much as 2,000 A.

Manufacturing of the CSM is ready to start inside 2022.

The Battery Affect Detection (BID) sensor system identifies each low-speed floor impacts and high-speed intrusions affecting the battery via Pedestrian Safety System stress sensors and air-filled silicone tubes within the backside of the battery compartment. The system then alerts the motive force. Continental says, “The time distinction between the sign’s arrival on the two stress satellites at each ends of the tube makes it attainable to calculate the realm of the affect.”

“As well as, the BID identifies the realm of the injury, so the battery administration [system] can empty the cells in that space to forestall any danger of fireside,” mentioned Managing Director of Continental Security Engineering Worldwide Johannes Clemm.

Continental says, “Compared to present metallic underfloor safety, the BID answer can save as much as 50 % of weight.”
