Battery pack power supply system for reducing burning probability of battery packs of electric vehicles

Abstract

Disclosed is a battery pack power supply system for reducing burning probability of battery packs of electric vehicles. Two battery pack boxes of the system can be automatically replaced, power source surge protectors of the battery pack boxes are connected with the battery pack boxes and capable of discharging leak current on the battery pack boxes, and power cords of the power source surge protectors are serially or parallelly connected with an input current power cord and an output current power cord in a filtering manner, so as to prevent burning of the battery packs caused by high-current attack during short circuit and charging. When the first battery pack's temperature still rises after up to 150 degrees Centigrade, a switch of the power source can be pressed to separate a front bracket of an electric jack from the battery pack boxes, and the first battery pack box is abandoned, similarly when the second battery box' temperature is out of control, temperature of the two battery packs is out of control and the two battery pack boxes can be abandoned and the electric vehicles can be pulled over nearby by means of freewheeling.

Description

[0001] Technical field: The present invention relates to the field of electric vehicle manufacturing, in particular to a battery pack power supply system that reduces the combustion probability of electric vehicle drive motor battery packs Background technique: [0002] 1. A pure electric vehicle is a vehicle that uses a single battery as the energy storage power source. The battery provides electric energy to the motor to drive the motor to run, thereby pushing the car forward. From the appearance point of view, there is no difference between an electric car and a car seen in daily life, the difference mainly lies in the power source and its drive system. That is, the motor of a pure electric vehicle is equivalent to the engine of a traditional car, and the battery is equivalent to the original fuel tank. [0003] It itself does not emit harmful gases that pollute the atmosphere. Even if the power consumption is converted to power plant emissions, except for sulfur and partic...

Problems solved by technology

[0017] In order to overcome the shortcomings of the existing electric vehicle battery charging system that the battery pack cannot be automatically replaced, the battery pack is short-circuited and burned after the electric vehicle is hit, and the battery pack is burned by excessive current, the present invention provides a battery that reduces the combustion probability of the electric vehicle battery pack. Group power supply system, the two battery pack boxes of the system can be replaced automatically, and the power surge protector attached to the battery pack box can be connected to the battery pack box to unload the leakage current on the battery pack box; the power surge protector with the The power line is connected in parallel or in series with the input current power line and output current power line to prevent the battery pack from burning due to short circuit and large current attacking the battery pack during charging.
