Problems solved by technology

[0003] Batteries have a potential explosion hazard during use, and the battery used in the car has a requirement for cruising range, resulting in a large volume of the car battery. Once the battery explodes, the consequences will be disastrous
In the prior art, most of the battery explosion-proof structures used in new energy vehicles still use the battery explosion-proof structures of mobile phones, dry batteries, etc., and some do not even have battery explosion-proof structures, and only optimize the program for the charging and discharging logic of the battery. is a security risk

Embodiment Construction

[0031] Below in conjunction with accompanying drawing, the present invention is described in detail.

[0032] In order to make the object, technical solution and advantages of the invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0033] like figure 1 As shown, a battery explosion-proof device is installed on the negative pole of the battery. When the battery outputs current to the outside, the current passes through the negative pole and reaches the power unit after the explosion-proof device; similarly, when the battery is charged, the current passes through the explosion-proof device. Charge. Including the explosion-proof cover 1, the interior of the explosion-proof cover 1 is hollow, and the explosion-proof cover 1 is made of...

Abstract

The invention discloses a battery explosion-proof device, belonging to the battery field. The battery explosion-proof device comprises an explosion-proof cover, wherein the explosion-proof cover is hollow and is made of conducting materials; and an explosion-proof valve is arranged below the explosion-proof cover and is hollow, a fusing block is arranged in the explosion-proof valve and supports the upper top surface of the explosion-proof valve, and the upper top surface is in contact with the lower surface of the explosion-proof cover and can elastically deform. The battery explosion-proof device has the characteristics that the safety performance of a secondary battery used by a new energy automobile can be further improved, the explosion and spontaneous combustion probabilities of the battery can be reduced, and meanwhile, the damage caused by the explosion and spontaneous combustion of the battery can be reduced.

Description

technical field [0001] The invention relates to a battery internal device, in particular to a battery explosion-proof device. Background technique [0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources, integrate advanced technologies in vehicle power control and drive, and form vehicles with advanced technical principles, new technologies, and new structures. Among them, the pure electric vehicle uses a single battery as the energy storage power source. It uses the battery as the energy storage power source, supplies electric energy to the motor through the battery, and drives the motor to run, thereby driving the car. The technology is relatively simple and mature, and it is a new technology at this stage. A hotspot in the development of energy vehicles. The power sources of most new energy vehicles mainly include lithium-ion batteries, nickel-metal hydride batteries, fuel cells and lead-acid batteries. The raw materials of l...
