example 1

[0034] This example illustrates the charger box provided by the present invention.

[0035] prepared as figure 1 Charger case shown. The solid-liquid-fixed phase-change material contains 65% by weight of polyethylene glycol (PEG, with a number average molecular weight of 1500), 20% by weight of low-density polyethylene (brand name is LL0209AA, produced by Liaoning Huajin Chemical (Group) Co., Ltd. Company produced) and 15% by weight of graphite, its preparation method is to blend and melt polyethylene glycol and low-density polyethylene at a temperature higher than their melting point (150°C), add graphite after thorough mixing, and finally The mixture of the three is poured into a battery support body and a case cover capable of embedding an AA-type battery, and cooled, the number of grooves 4 on the support body 2 and the number of grooves 4 on the case cover 3 are 4, The upper and lower grooves 4 correspond to one another, and when the support body 2 and the cover 3 are c...

example 2

[0037] This example illustrates the charger box provided by the present invention.

[0038] Prepared according to the method for example 1 such as figure 1 The charger box shown, the difference is that the solid-liquid fixed phase change material contains 50% by weight of polyethylene glycol (PEG, number average molecular weight is 1000) and 50% by weight of polyethylene (brand is HD5070EA, manufactured by Liaoning Huajin Chemical (Group) Co., Ltd.) mixture, which is prepared by blending and melting polyethylene glycol and polyethylene at a temperature higher than their melting point (150°C), fully mixing and pouring to form the present invention. The battery support and case cover described above are cooled.

Abstract

The invention provides a battery charger box, comprising a casing, battery support body fixed on the casing and a casing cover adapted to the casing, where the support body and the casing cover are made of solid-liquid shaping phase change material or solid-solid phase change material, the phase change temperature of the phase change material is -10deg.C-60deg.C. And it can effectively control the battery temperature in the charging course, assuring battery charging efficiency and battery operating performance and prolonging battery service life. And the battery changer box has advantage of low cost.

Description

technical field [0001] The invention relates to a battery charger box, more specifically, the invention relates to a charger box which can effectively control the temperature rise of the battery during the charging process. Background technique [0002] General secondary batteries will release heat during charging and discharging, which will increase the temperature of the battery itself, especially during the rapid charging process, the temperature will rise even higher, and general secondary batteries have their corresponding optimal conditions. Charging and use temperature range, such as Ni-Cd, Ni-MH batteries at -10-60°C, Li-ion batteries at 0-60°C, if the battery temperature exceeds this temperature range during charging, the charging efficiency of the battery It will be extremely low, or even unable to charge normally. Nowadays, in order to save time and improve work efficiency, the charging requirements for secondary batteries are generally developing in the directio...
