TRDU5

PRODUCT SPECIFICATIONS SGX – TRDU5 Battery Thermal Runaway Detection TRDU-5 TRDU5 is a Battery Failure Detection sensor that measures H2, CO, NH3, Pressure, Temperature and Humidity level when different battery leakage occur. The module has to be placed in the battery enclosure allowing to detect a failure mode. TRDU5 is a solution to allow Battery Management System (BMS) monitor the safe operation of the battery and send an earlier signal during a thermal runaway warning to give time to passengers to leave the vehicle safely. Features :  Automotive product  Fast response time (< 1 s)  MEMS sensor technology for H2, CO and NH3  Absolute pressure sensor inside  High sensitivities to gases H2, CO, NH3 and Hydrocarbons  Measurement redundancy (gases, pressure, temperature, humidity)  LIN 2.1 output  Thermal Runaway Trigger Signal can be setup  Standard 3 pins connector  Watertight housing IP6K7 Specifications TRDU5 Page 1 of 9 Rev. 3.1 1 Functional specifications 1.1 Principle There are different failure mode during the battery life time that could occur. To prevent any injury to the passengers, one solution is to send an alarm as soon as possible to the passenger to leave the car when there is any leakage detection. Our sensors are able to detect different gases, pressure change and environmental changes during a thermal runway. All the failure mode are cover and earlier than any other single sensor element. The TRDU5 product is giving to the customer different strategy and robustness to catch up all the cases for a quick reaction.
