What battery is used at low temperature?solar powered battery pack Manufacturing

　　In fact, everyone who asked this question knows that he wants to use special low -temperature batteries. The editor thinks that the question is mainly to ask the specific battery type. So far, the core low -temperature technology controlled by national high -tech enterprises is mainly two types of batteries, low -temperature iron phosphate batteries and low -temperature alien batteries (that is, low -temperature polymer batteries). The batteries use more complicated scrolls.

　　Among them, the low-temperature iron phosphate battery is discharged at 0.5C at -40 ° C, and the discharge capacity exceeds 60%of the initial capacity; at -35 ° C is discharged at 0.3C, the discharge capacity exceeds 70%of the initial capacity, and it can be at -20 ° C. Charge. According to the latest official data, the minimum working environment of the polymer battery is broken to the low temperature range of -50 ° C to 50 ° C. The minimum is at -50 ° C discharge at 0.2C, with an efficiency of more than 60%; in the -40 ° C environment, in the -40 ° C environment, in the environment of -40 ° C, in the -40 ° C environment, in the environment of -40 ° C, in the -40 ° C environment, in the -40 ° C environment, in the environment of -40 ° C, in the -40 ° C environment, in the environment of -40 ° C, in the -40 ° C environment, in the -40 ° C environment, in an environment of -40 ° C, in the -40 ° C environment, in an environment of -40 ° C, in an environment of -40 ° C, in the environment of -40 ° C, With 0.2C discharge, the discharge capacity reaches 80%; the environment is charged at 0.5C at the -30 ° C environment, and the capacity remains above 85%after 300 times.
