Low-temperature self-heating high-temperature heat dissipation lithium battery and control method

Abstract

The invention discloses a low-temperature self-heating high-temperature heat dissipation lithium battery and a control method and belongs to the technical field of lithium batteries. The low-temperature self-heating high-temperature heat dissipation lithium battery comprises a box body; a battery mounting plate is arranged at the lower end of the inner wall of the box body; at least seven coiled pipes are arranged at the top of the battery mounting plate; every two adjacent coiled pipes are communicated with each other; single batteries located on the inner sides of the coiled pipes are arranged at the top of the battery mounting plate; single battery temperature sensors are arranged in the single batteries; and a fan located below the battery mounting plate is arranged on the left side ofthe box body. The heat dissipation effects of most of existing lithium battery packs are emphasized; and in some cold areas or cold time periods in winter, due to the fact that an external environment is low, the working environment of the lithium batteries is low, the existing lithium batteries are not provided with temperature adjusting devices, and as a result, the temperature of the batteriesis too high or too low, and the lithium batteries are prone to being damaged. However, with the low-temperature self-heating high-temperature heat dissipation lithium battery and the control method of the invention adopted, the above problem can be solved.

Description

technical field [0001] The invention relates to the field of lithium batteries, more specifically, to a low-temperature self-heating high-temperature heat dissipation lithium battery and a control method. Background technique [0002] Lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium ion batteries do not contain metallic lithium , and is rechargeable. Lithium metal batteries, the fifth generation of rechargeable batteries, were born in 1996, and their safety, specific capacity, self-discharge rate and performance-price ratio are superior to lithium-ion batteries. Due to its own high technical requirements, only companies in a few countries are currently producing such lithium metal batteries. [0003] When the existing lithium battery pack is worki...

Problems solved by technology

[0005] In view of the problems existing in the prior art, the object of the present invention is to provide a low-temperature self-heating and high-temperature heat dissipation lithium battery and a control method, which can regulate the temperature in the lithium battery pack, and protect the battery from burning out or The advantage of frost damage solves the problem that most of the existing lithium battery packs emphasize its heat dissipation effect, but in some cold areas or during colder winter periods, due to the low external environment, the working environment of lithium batteries is low, and the existing The lithium battery lacks a temperature regulating device, which can easily cause the battery temperature to be too high or too low, which can easily lead to damage to the lithium battery
