Problems solved by technology
The lead-acid battery pack is managed as a whole group. When a problem occurs in one of the lead-acid batteries, even if the other lead-acid batteries have not failed, it will cause the failure of the entire battery pack and seriously shorten the power supply time of the lead-acid battery pack. What's more, the whole set of lead-acid battery packs cannot be used normally
At present, the lead-acid battery pack is managed by the whole set of discharge, which cannot differentiate and manage the charge and discharge time of each lead-acid battery in the lead-acid battery pack, which will inevitably lead to overcharge / discharge of the lead-acid battery pack. The problem of undercharging or overdischarging / underdischarging will seriously affect the service life of the lead-acid battery and the utilization rate of battery power, and cannot guarantee the safe and stable operation of the communication base station

The invention provides a balanced charging and discharging control method and system for a communication base station. The method comprises the following steps: carrying out the distinguishing detection and management of each battery in a battery pack, collecting the terminal voltage, charging current and temperature of each battery, carrying out the constant-current charging, constant-voltage charging and floating charging of each battery, adjusting the floating charge voltage according to the temperature of the battery in the floating charge process, and carrying out three-stage charging of constant current, constant voltage and floating charge on each battery.The condition of over-charge/under-charge or over-discharge/under-discharge of the battery can be effectively prevented, so the service life of the battery is effectively prolonged, the battery power utilization rate is effectively improved, and safe and stable operation of the communication base station is ensured.
Description
technical field [0001] The invention relates to the technical field of power consumption management of communication base stations, in particular to a method and system for equalizing charge and discharge control of communication base stations. Background technique [0002] At present, most communication base stations use lead-acid battery packs as backup power for energy storage. The lead-acid battery pack is managed as a whole group. When a problem occurs in one of the lead-acid batteries, even if the other lead-acid batteries have not failed, it will cause the failure of the entire battery pack and seriously shorten the power supply time of the lead-acid battery pack. What's more, the whole lead-acid battery pack cannot be used normally. At present, the lead-acid battery pack is managed by the whole set of discharge, which cannot differentiate and manage the charge and discharge time of each lead-acid battery in the lead-acid battery pack, which will inevitably lead to o...
