A power supply system with automatic switchover voltage for vehicle control unit is proposed. The system comprises a supply communication module configured to communicate with a vehicle control unit, the supply communication module comprising a power supply module to provide power for a vehicle control unit; and a communication device coupled to the supply communication module for showing power supply status; wherein the supply communication module provides a first direct voltage and communicates with the vehicle control unit before supplying power, and if the supply communication module does not receive any message from the vehicle control unit within a first time interval, the supply communication module automatically switches to a second direct voltage from the first direct voltage or automatically increases the first direct voltage within a second time interval, and supplies power to the vehicle control unit; and wherein the second direct voltage is greater than the first direct voltage.

Power supply system for vehicle control unit and method thereof

A method of intelligent power distribution for a charging system with double charging terminals is provided. The method of the present invention comprises the following steps, determining whether a first vehicle is requesting for charging or not. Then, the next step is determining whether a second vehicle is charging in the system or not. If the determination is affirmative, the first vehicle is then charged by remainder power modules. In the following, it is determining whether remainder power modules can be used for a second output terminal. Subsequently, it is determining whether the first vehicle needs more power by charging. If the determination is affirmative, the remainder power modules are charging to the first vehicle via the second output terminal.

Method of intelligent power distribution for system with double charging terminals

A charging method on constant current mode includes communicating with a rechargeable battery by a central control module to obtain a first current and a first voltage required to charge the rechargeable battery; receiving a first current output instruction and a first voltage output instruction by first and second charging modules; outputting a second voltage and a second current to the rechargeable battery and transmitting an output value of the second voltage and an output value of the second current to the central control module by the first charging module; and when the central control module detects that difference between the output value of the second voltage and the first voltage is smaller than a predetermined voltage value, transmitting a fourth current output instruction, in which a fourth current equals the first current minus a predetermined current value, to the first charging module by the central control module.
