Currently China already classified new energy vehicles as one of the seven strategic emerging industries. The development of new energy vehicles is one of the important measures to reduce oil consumption and carbon dioxide. The government has introduced relevant support breeding policies to create a favorable policy environment for the development of new energy vehicles.

New energy vehicle types include pure electric vehicles, hybrid vehicles, fuel cell electric vehicles and so on. Compared with the traditional fuel-efficient vehicles, the advantage of new energy vehicles is using the power batteries as the power drive.In order to intelligently manage and maintain each battery cell, also prevent the battery overcharge/over discharge and extend the battery life while monitoring the situation of the battery, a battery management system (BMS) should be used.

The temperature sensors used in new energy vehicles mainly include sensors to detect battery temperature, temperature sensors to monitor the motor, and temperature sensors to be used in the battery cooling system. Which NTC temperature sensor needs NTC thermal chip as the core components,it applies double-layer package form temperature sensor used in electric motor, then transferring the temperature variety into the desired electronic signal variables.

Our NTC thermistor chip includes gold electrode and silver electrode. Silver electrode thermal die chip temperature range of -55 ℃ ~ 300 ℃, gold electrode thermal chip temperature can be as high as above 300 ℃. The thermal conductivity of the chip is good for the production of new energy vehicles used in the temperature sensor, the motor will continuously maintaining the high temperature environment act with fast response.
