Embodiment Construction

[0064] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0065] refer to figure 1 , is a high-voltage power distribution control method disclosed in the present invention, comprising:

[0066] S1: Communicate with the outside world to determine how the circuit works. The working mode information transmitted from the outside is received through the CAN bus. Since the transmitted data is encoded, it needs to analyze the data to obtain the working mode information, and determine the working mode of the circuit through the working mode information.

[0067] S2: Check the operation of the circuit. Before the circuit runs normally, apply a small current to the circuit, and make the circuit work according to the working mode information while applying the small current, so as to simulate the normal working state, and determine whether there is a problem in the operation of the circuit through the working structure of th...

Abstract

The invention relates to the field of power distribution control, and discloses a high-voltage power distribution control method and system. The method comprises the steps that S1, communication withthe outside is conducted to determine a working mode of a circuit; S2, the running conditions of the circuit are detected; S3, states of elements and devices of the circuit are detected; S4, the running conditions and the states of the elements and the devices are acquired, and the elements and devices with faults are determined; S5, the elements and devices of the circuit are controlled accordingto the work mode, and power distribution operation is achieved; S6, the environment temperature of the circuit, the temperature of the elements and the devices and the temperature of junction pointsare detected; S7, current conditions of the circuit are detected; S8, the operation conditions of a user are determined for processing. The system comprises a bus communication unit, a self-inspectionunit, an element-device monitoring unit, a processing unit, a circuit control unit, a temperature detecting unit and a high-voltage interlocking unit. The method and system have the advantage that the personal injury phenomenon is reduced.

Description

technical field [0001] The invention relates to the technical field of power distribution control, in particular to a high-voltage power distribution control method and system thereof. Background technique [0002] At present, an electric vehicle refers to a vehicle powered by a vehicle-mounted power battery and driven by a motor to drive the wheels. The power battery provides electric energy for the driving motor of the electric vehicle, and the electric motor converts the electric energy of the power battery into mechanical energy, and drives the wheels and working devices through the transmission or directly. In an electric vehicle, there are far more electrical devices than in conventional vehicles. Therefore, in addition to the low-voltage control system, there is also a high-voltage transmission system in the vehicle. The operating voltage of many devices in electric vehicles is as high as hundreds of volts, and the current is as high as tens of amps, or even hundred...
