Protection device for reducing explosion damage of vehicle lithium ion battery

Abstract

The invention discloses a protection device for reducing explosion damage of a vehicle lithium ion battery, which comprises a vehicle body shell, and is characterized in that the interior of the vehicle body shell is fixedly connected with a storage battery through screws, a temperature rise regulation and control mechanism is arranged on the outer side of the storage battery, and a power steering mechanism is arranged in the vehicle body shell; a power compensation mechanism is arranged in the vehicle body shell, the temperature rise regulation and control mechanism is fixed to the outer side of the storage battery and located in the vehicle body shell, the power steering mechanism is in transmission connection with the temperature rise regulation and control mechanism, the power compensation mechanism is fixed to the vehicle body shell, and the temperature rise regulation and control mechanism comprises two loading shells. The two loading shells are hinged to the positions, located on the two sides of the storage battery, in the vehicle body shell correspondingly, and a loading barrel is hinged to the position, located on the outer side of the storage battery, between the two loading shells, and the protection device has the beneficial effects that the temperature of the battery can be effectively guaranteed in winter, and a driver and a vehicle are effectively protected when spontaneous combustion occurs.

Description

technical field [0001] The invention relates to the technical field of vehicle batteries, in particular to a protection device for reducing explosion damage of vehicle lithium-ion batteries. Background technique [0002] Lithium-ion battery is an essential power source in the car starting system. During the process of starting and running the car, the lithium-ion battery will gradually heat up. Its power generation principle is to use chemical reactions to generate electricity. In winter, the temperature drops, the temperature of the solution in the battery drops, and the activity of the substances in it also decreases. When a chemical reaction occurs, the amount of electricity generated and released will decrease a lot. For lithium-ion batteries, the most powerful temperature for power release is around 25 degrees. Once the temperature is lower than 15 degrees, the battery will generate less than two-thirds of the original power. If the temperature drops below 0 degrees, t...

Problems solved by technology

[0003] However, the existing lithium-ion battery protection devices for vehicles have poor practicability; at the same time, the existing lithium-ion battery protection devices for vehicles cannot effectively control the temperature of the battery, and it is difficult to effectively protect the driver when the battery spontaneously ignites and smokes.
