Abstract

The invention relates to a control circuit for battery high-temperature charging protection, which comprises a diode (D1) and a direct current contactor (K1), wherein the direct current contactor comprise a coil pin 1, a coil pin 2, a third contact point and a fourth contact point; the negative electrode (D1) of the diode and the fourth contact point of the direct current contact (K1) are connected with the positive electrode of a power supply (Power +); the positive electrode (D1) of the diode and the third contact point of the direct current contact (K1) are connected with the positive electrode of a battery (Battery); the coil pin 1 of the direct current contactor (K1) is connected with a microcomputer control circuit to output a control signal (Signal); and the coil pin 2 of the direct current contactor (K1) is connected with the negative electrode of the power supply (Power -). The invention can effectively control the operation temperature of the battery, and prolong the service life of the battery.

Description

technical field [0001] The invention relates to a battery high temperature charging protection control circuit. Background technique [0002] The normal operating environment temperature of the battery is designed to be 25°C, and the service life will be reduced by 50% every time the temperature rises by 10K. Therefore, for the communication base station, in order to ensure that the battery maintains a normal operating temperature, a certain amount of additional cooling energy will be consumed. It is not conducive to energy saving and emission reduction; if the operating temperature of the battery is not controlled, the service life of the battery will be greatly reduced, causing excessive scrapping of the battery and an increase in operation and maintenance costs. Therefore, from the perspective of environmental protection, energy saving and operating cost, it will be a future trend to use the battery high temperature charging protection circuit to intelligently control bat...
