Problems solved by technology

In the power supply system of pure electric vehicles at this stage, the high voltage output by the power battery is supplied to drive the motor to drive the vehicle, while the low-voltage electrical equipment on the vehicle needs to be driven by low-voltage direct current, which requires the installation of a DC / DC converter in the electronic control system. High voltage is converted to low voltage, but in actual use, due to the large heat generated by the DC / DC converter, overheating damage often occurs, and even the bus harness is burned. At present, there is no effective means in the industry to reduce the heat generated by the DC / DC converter or failure rate
The common improvement method is to add various sensors, such as temperature sensors, to detect the working status of the DC / DC converter in real time, but the above technical solutions can only alleviate or detect possible failures to a certain extent, and cannot really solve the problem
At the same time, the high cost of the DC / DC converter is not conducive to reducing the overall cost of the electronic control system

Abstract

The invention discloses a pure electric vehicle auxiliary low-voltage power supply system, which includes a drive motor and a generator connected to the output end of the drive motor through a transmission device, and the output end of the generator is electrically connected to the vehicle-mounted low-voltage electrical equipment; The generator is a low voltage direct current generator. The invention solves the problem in the prior art that the DC / DC converter is prone to heat and causes failure, and effectively reduces the failure rate.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicles, and in particular relates to an auxiliary low-voltage power supply system for pure electric vehicles. Background technique [0002] With the rapid development of new energy and other industries, pure electric vehicles are becoming more and more popular. They are not limited to small passenger vehicles, and have further appeared in medium and large passenger vehicles and engineering vehicles. In the power supply system of pure electric vehicles at this stage, the high voltage output by the power battery is supplied to drive the motor to drive the vehicle, while the low-voltage electrical equipment on the vehicle needs to be driven by low-voltage direct current, which requires the installation of a DC / DC converter in the electronic control system. High voltage is converted to low voltage, but in actual use, due to the large heat generated by the DC / DC converter, overheating damage often...
