The charging and changing of power system and the design of power supply and distribution system are important components of electric heavy truck. Through reasonable design and solving key problems, we can provide efficient, reliable, safe and sustainable charging and replacement services.
In terms of charging design, the use of fast charging technology can improve charging efficiency and user experience, but the problem of battery overheating and loss needs to be solved. The power supply and distribution system must have a stable power supply and sufficient capacity. At the same time, the device layout and space restrictions must be considered to ensure the stability of the power supply system and the security of charging and replacing devices.
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.
