Latest company case about 3.6V 500mAh TBOX NI-MH Battery Design Solution of On-board Arithmetic Unit With Wide Temperature Range

 

Equipped OBD device with 4G LTE (Internet of Vehicles standard T-Box) will deeply connect CANBUS system and read the ultrasonic signal of door and window lamp, rearview mirror and trunk. It perfectly realizes automatic air conditioner and remote automatic seat adjustment and reads the information of CAN system of safety airbag status and tire pressure so as to invent more intelligent application related to people and car, such as HUD, intelligent video and audio, high-fidelity music, remote business video conference, etc.

 

T-box, the standard terminal of Internet of vehicles, is a new product oriented to demand and improving the industrial economic structure of 4S shop group. It is realized by using wireless communication technology through the processing chip of vehicle standard. Based on the severe requirements of reliability, working temperature, anti-interference and other aspects of "automotive grade", it mainly realize the functions of 4G remote wireless communication, GPS satellite positioning, acceleration sensing and CAN communication, and online application of remote vehicle monitoring, remote control, safety monitoring, alarm system, remote diagnosis, etc.
