Self-temperature-regulating lithium titanate battery module

Abstract

The invention discloses a self-temperature-regulating lithium titanate battery module which comprises an external cabinet body and an internal cabinet body mounted in the external cabinet body, and an elastic rope is fixedly connected between the internal corner position of the external cabinet body and the external corner position of the internal cabinet body; the module also comprises battery module bodies which are arranged in the inner cabinet body and are uniformly distributed at equal intervals; the module is characterized by further comprising a circulation hole arranged on the inner cabinet body; a temperature adjusting assembly fixed at the bottom of the outer cabinet body; a temperature control assembly and a motor respectively fixed at the top and the bottom of the outer wall of the right side of the outer cabinet body; and an air inlet pipe, wherein the lower end of the air inlet pipe is connected to the top edge position of the temperature adjusting assembly in a penetrating mode. According to the self-temperature-regulating lithium titanate battery module, the impact-resistant protection effect of the battery module in a severe environment is greatly improved, and the working environment temperature is regulated and changed while the fluidity of liquid is utilized for protection.

Description

technical field [0001] The invention relates to the technical field related to lithium titanate batteries, in particular to a self-regulating temperature lithium titanate battery module. Background technique [0002] Lithium titanate battery is a new type of lithium ion battery with high safety, high stability, long service life and green environmental protection characteristics. In order to meet the routine power supply in extreme weather environments, it will also be used in low temperature In the extremely cold environment, provide the electricity needed for life for low temperature workers; [0003] However, the existing lithium titanate battery modules for low temperature operation have the following problems in use: [0004] 1. It only routinely satisfies the conditions of its operation in a low-temperature environment. When in use, it is easy to limit its opening function due to too low temperature, and it is impossible to monitor and adjust the ambient temperature i...

AI Technical Summary

Problems solved by technology

[0007] The object of the present invention is to provide a self-regulating lithium titanate battery module to solve the above-mentioned background technology. The existing lithium titanate battery module only meets the conditions when it is operated in a low temperature environment in a conventional way. When the temperature is too low, it is easy to limit its opening function due to the low temperature, and it is impossible to monitor and adjust the ambient temperature in real time, and adjust the temperature change, which may easily lead to heat loss or low-temperature freezing damage of the battery module. The protection performance of the battery module Low, easily due to external forces in the external environment, shocks caused by kinetic energy transmission, collision damage to internal structures, and insufficient external force unloading and weakening effects
