Problems solved by technology

However, the heat transfer coefficient between the gas and the battery wall is low, the cooling speed is slow, and the efficiency is low. Moreover, due to the inconsistency of the heat generation and heat transfer characteristics of the battery pack itself and the temperature of the introduced ambient air, the overall temperature of the battery pack will have a large The unevenness of the battery; the liquid cooling method is used to adjust the battery working temperature: the heat transfer coefficient between the liquid cold plate and the battery wall is high, and the cooling and heating speed is fast
However, the water-cooling system requires components such as water jackets and heat exc

[0026] Example

[0027] like Figure 1-8 As shown, an auxiliary constant temperature battery box, the battery box includes an outer shell 3, an inner shell 1, a pole cover 2, a low boiling point medium 4, a heating plate 5 and a cooling plate 6, and a three-sided conductor is formed between the outer shell 3 and the inner shell 1. A closed sealed cavity, the pole cover 2 is set outside the inner shell 1, the low boiling point medium 4 is set in the sealed cavity, and the heating plate 5 and the cooling plate 6 are respectively set at the bottom and top of the shell 3. The inner shell 1 is provided with an inner shell welding platform 7 and a rib boss 8 for welding.

[0028] The steps of assembling the above-mentioned auxiliary constant temperature battery box are as follows: first, place the outer shell 3 in a negative pressure environment, fill it with an appropriate amount of low-boiling point medium 4, then place the inner shell 1 of the battery in the outer shell 3, and p...

Abstract

The invention relates to an auxiliary constant-temperature battery box. The battery box comprises an outer shell, an inner shell, a polar column cover, a low-boiling-point medium, a heating plate and a cooling plate, wherein the inner shell is arranged inside the outer shell; a sealed cavity is formed between the outer shell and the inner shell; the polar column cover is arranged inside the inner shell; the low-boiling-point medium is arranged in the sealed cavity; the heating plate and the cooling plate are respectively arranged at the bottom and the top of the outer shell; and when the temperature of a battery pack in the battery box needs to be reduced or raised, the battery box changes the phase of the low-boiling-point medium through the heating plate or the cooling plate, so that the aim of maintaining the constant temperature of the battery pack in the battery box is achieved. Compared with the prior art, the auxiliary constant-temperature battery box has the advantages of high efficiency, capability of effectively adjusting the working temperature of the battery pack, simple structure and the like.

Description

technical field [0001] The invention relates to a battery box, in particular to an auxiliary constant temperature battery box. Background technique [0002] The working temperature adjustment method of traditional battery system is mostly air-cooled or liquid-cooled. The contact surface conducts heat exchange, so as to achieve the purpose of regulating the working temperature of the battery. [0003] Adopt air-cooling method to adjust battery working temperature: the system has simple structure, light weight, effective ventilation when harmful gas is generated, and low cost. However, the heat transfer coefficient between the gas and the battery wall is low, the cooling speed is slow, and the efficiency is low. Moreover, due to the inconsistency of the heat generation and heat transfer characteristics of the battery pack itself and the temperature of the introduced ambient air, the overall temperature of the battery pack will have a large The unevenness of the battery; the ...
