The vehicle controller is installed on the power change heavy truck/mining card, and monitors the running status of the vehicle and the real-time data of the BMS system through the CAN bus. Through the local WIFI communication, it can communicate with the station control system of the changing station, controlled by the station control system to complete the automatic and manual power replacement of the vehicle battery. With 4G wireless communication function and GNSS positioning function, and remote communication with the cloud platform, can remotely monitor the running status of the vehicle, remote fault diagnosis, alarm and vehicle positioning.
The vehicle controller has the function of power failure detection and automatic data saving. With off-chip RTC real-time clock and power failure backup battery. It has the functions of power anti-reverse connection, over-current protection and over-voltage protection.
Automatic power change control
TBOX obtains the vehicle VIN code through the CAN interface, automatically establishes a communication connection with the control system of the power changing station through the local WIFI, carries out information exchange between the control system of the power changing station and the power changing vehicle, and completes the unlocking operation of the battery before and locking operation after the power changing.
Manual power change control
TBOX supports two communication control modes: local station control system WIFI network and cloud platform 4G communication. According to actual needs, the car battery can be unlocked and locked manually by the local station control system or cloud platform.
Vehicle status data report
TBOX collects vehicle status data such as BMS in real time through CAN communication, reports the data to the operation and management cloud platform in real time through 4G network;
Power change data record
TBOX supports local data saving, and records and saves the relevant information of vehicle power change;
Automatic dormancy
After the vehicle is turned off for a long time, the TBOX can automatically enter the hibernation state;
Power-off protection
TBOX supports power failure detection. When a power failure occurs, you can perform data protection before power failure.
