Abstract

The invention aims to provide an externally-hung type electric shock preventing device of batteries. By means of the externally-hung type electric shock preventing device of the batteries, when a vehicle has an accident or is repaired, power outage is conducted automatically or manually, and therefore the situation that people are injured because of electric shock can be avoided. The externally-hung type electric shock preventing device of the batteries comprises a control device, wherein the control device is arranged between the power batteries of the vehicle and a power source and is electrically connected with the power batteries of the vehicle and the power source, moreover, a sensing device is arranged in the vehicle, and the control device is composed of a control circuit board and a power outage judgment module. The power outage judgment module monitors the state of the sensing device through communication interfaces, can compare return signals with a default judgment benchmark of the power outage judgment module, and therefore judges whether a battery management module makes the power batteries stop electricity supply under the condition that a control battery of the vehicle is not switched off. A vehicle body sensor is also contained in the sensing device, so that when the vehicle body deforms and the return signals are larger than the judgment benchmark, the power outage judgment module can operate, and the battery management module is controlled to make the power batteries stop electricity supply.

Description

technical field

[0001] The invention relates to an electric shock protection device for an external battery, in particular to a battery safety device which can be installed on a vehicle and can avoid the occurrence of electric shock casualties. Background technique

[0002] In recent years, the worsening global warming phenomenon and the oil crisis have forced mankind 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 field of environmental protection and energy conservation.

[0003] In order to meet the performance requirements and increase the cruising range of electric vehicles, the power system mostly uses high-voltage electricity of more than 300 volts, and runs around with high-voltage electricity. Security protection strategies become extremely important.

[0004] Generally, car factories will install leakage circu...
