Problems solved by technology

However, this kind of battery cannot solve the problem of battery burning and explosion caused by leakage and other factors.
And the device requires the internal pressure in the battery pack shell to be between -0.09Mpa and -0.01Mpa, which is in a negative pressure state, and it is difficult to manufacture and maintain

Abstract

The invention provides an evaporative cooling flame retardant battery system which is simple in structure, economical and durable, has a good heat dissipation function and has a flame retardant function. The evaporative cooling flame retardant battery system comprises a battery, a tank body, cooling liquid, a connector, a pressure relief valve, an electromagnetic valve, a cooler, a pipeline and total positive/negative connector and a pressure sensor; the battery is connected with the connector, and is immersed in the cooling liquid; the cooling liquid is fluorocarbon. The evaporative cooling flame retardant battery system has heat dissipation and flame retardant functions at the same time; the evaporative cooling flame retardant battery system has a simple structure and does not need special maintenance; the internal temperature balance and heat dissipation of the system are operated spontaneously, fans, pumps and other equipment are not needed in the internal of the system; compared with the traditional air cooling and liquid cooling, the heat dissipation effect of the system is better, the structure is simpler, the safety is higher, and the system is especially suitable for a high-power-density battery system.

Description

technical field [0001] The invention belongs to the technical field of battery system preparation, and in particular relates to an evaporative cooling flame-retardant battery system. Background technique [0002] Due to the increasingly frequent use of electric energy and the higher and higher requirements for battery life of electrical devices, large-capacity batteries have been widely used. However, the corresponding heat dissipation problem of this type of battery has also attracted people's attention, and a variety of battery systems with flame-retardant or efficient cooling functions have been developed. [0003] CN 104347840 A A leaking flame-retardant structure of a lithium-ion battery pack is obtained by adding a sponge for absorbing leaked electrolyte and setting other corresponding structures. CN 103682188 A realizes the effects of preventing explosion, avoiding short circuit and improving battery safety performance by introducing two cavities and adding protectiv...
