Problems solved by technology

[0003] However, for purely electric-driven buses, the low-voltage or low-voltage control equipment of existing electric buses is relatively simple, and cannot meet the operation needs of each electric component of a purely electric-driven vehicle
If the existing equipment is only used, it will cause the voltage instability of the car and affect the safe driving

Abstract

The invention relates to control equipment for a direct current low-voltage device of an extended range type electric vehicle. The control equipment comprises an equipment containing box, wherein a box cover is arranged on the equipment containing box; the control equipment is characterized in that a plurality of communication connectors are installed on the equipment containing box; a convenient plug-in control circuit board is arranged in the equipment containing box; a connecting slot is formed in the convenient plug-in control circuit board; a CAN (Controller Area Network) communication device, low-voltage control equipment and low-voltage power distribution equipment are communicated with each other and are respectively connected with the connecting slot; and a communication connector is connected with an auxiliary communication port of the low-voltage control equipment. Therefore, the requirements on normal operation of all low-voltage equipment of the extended range electric vehicle can be satisfied under conditions of pure electric mode and extended range mode without additional control components, and the safety of low-voltage components of the vehicle is furthest guaranteed. Moreover, the control equipment has a simple structure, better firmness level and heat dissipation effect.

Description

technical field [0001] The invention relates to a control device, in particular to a control device for a DC low-voltage device of an extended-range electric vehicle. Background technique [0002] For conventional vehicles, due to the fault diagnosis function of gear position, accelerator pedal, etc., the vehicle will not experience undesired acceleration, deceleration and reverse. When the main motor and controller fail, the controller will protect itself and stop The vehicle controller also decrements its controller enable signal and throttle to zero. When the electrical connection is disconnected unexpectedly, the signal is in the open circuit mode, and the signal is 0, which will not cause danger to the vehicle; and the communication overtime technology is used to ensure that the communication failure caused by the disconnection of the communication line will not cause danger to the vehicle. A manual air circuit breaker is connected in series in the general circuit of t...
