Sealed Coolant Temperature Sensor

The Coolant Temperature Sensor (CTS) monitors the temperature of the coolant that is pumped around the battery to cool the battery module in Electric Vehicles (EV) and Plug-in Hybrid Electric Vehicles (PHEV). The purpose of this sensor technology is to relay signals to the battery thermal management system (BMS) in the event of overheating. Should this happen, the vehicle can be stopped and the charging switched off before the heat causes any permanent damage to the battery.
