Battery anti-shock device

Abstract

The invention aims to provide a battery electric-shock-resisting device. The device can actively cut off a power supply or a person can manually cut off the power supply when a vehicle has an accident or is repaired, so that a casualty accident caused by electric shock can be avoided. The device comprises a control device provided with a power managing function. The control device is arranged in a power battery of a vehicle provided with a sensing device, the power battery is electrically connected with a power source of the vehicle, the control device is composed of a circuit board, a battery managing module and an outage judging module, and the outage judging module is provided with a communication interface and can monitor the operating state of the sensing device and judge whether power supply is cut off or not through comparison between a signal returned by the sensing device and a judgment benchmark. The sensing device also comprises a vehicle body sensor. When a vehicle body is deformed, on the condition that the power supply of a control battery of the vehicle is not cut off, the outage judging module is made to operate, and the battery managing module is made to stop supplying power.

Description

technical field [0001] The invention relates to a battery electric shock prevention device, in particular to a battery safety device which can be installed on a vehicle and can avoid electric shock casualties. Background technique [0002] The deteriorating global warming phenomenon and the oil crisis in recent years have forced human beings to seek energy-saving and environmentally friendly alternative energy sources. At this stage, the development of high-power lithium batteries for use in electric vehicles is the most important part of the current environmental protection and energy-saving fields. [0003] In order to meet the performance requirements and increase the cruising range of electric vehicles, the power system uses more than 300 volts of high-voltage electricity, and runs around with high-voltage electricity. In order to avoid electric shock hazards for drivers and passengers and maintain road safety, leakage detection and Security protection strategies become ...

AI Technical Summary

Problems solved by technology

However, for electric vehicles, this action is very problematic, because if the vehicle body is deformed and the insulation layer of the power line is not damaged, the earth leakage breaker will not operate. Electric vehicles still have high-voltage electricity, once the oil pressure cuts the power line, not only will the ambulance personnel get an electric shock, it is even more likely that the injured will receive an electric shock, which is very dangerous

[0007] On the other hand, the existence of the leakage breaker can avoid the possibility of electric leakage and electric shock, but in the case of a vehicle accident, once the leakage breaker fails, it may cause the injured to get an electric shock and aggravate the injury of the injured. In severe cases, it is more likely to endanger the lives of the injured
