How to make the balance of high temperature lithium battery waterproof?
If you want to balance quickly during discharge, you must connect the low resistance resistor in series with the power transistor to reduce the power consumption of the power transistor. Without this current limiting resistor, the transistor will quickly consume the power of waterproof high-temperature lithium battery.
Measuring the voltage of waterproof high-temperature lithium battery during charging is not correct, and it will lead to premature equalization of waterproof high-temperature lithium battery. Therefore, the charging must be ended periodically in order to measure the battery voltage. The equalization during charging requires an external power transistor with low on resistance to achieve battery equalization, which will show the same limitations as the equalization during discharge.
The balanced treatment process design is very important in a waterproof high-temperature lithium battery system. At the beginning, the balanced treatment is inseparable from both the high-temperature lithium battery system of electric forklift and the high-temperature lithium battery system of new energy vehicles. The internal balance tube of battery assembly should be in the middle, whether it is the traditional lead-acid battery or the waterproof high-temperature lithium battery that was very popular at the beginning, The function is not the function of a single cell, but more depends on the balanced tube sensing function of the overall waterproof high-temperature lithium battery pack.
