Energy storage battery full-life-cycle intelligent charging and discharging maintenance device and control method

Abstract

The invention provides an energy storage battery full-life-cycle intelligent charging and discharging maintenance device and a method. The full-life-cycle intelligent charging and discharging maintenance device comprises an HMI control screen, a DSP control mainboard and a maintenance circuit. The HMI control screen is in communication connection with the DSP control mainboard, and the DSP control mainboard is connected with the maintenance circuit; the maintenance circuit comprises an energy storage battery interface, a charging and discharging main circuit, a system protection module, a high-power charging power supply and a load box. Specifically, the energy storage battery interface is connected with the charging and discharging main circuit, the charging and discharging main circuit is connected with the load box, and the charging and discharging main circuit is further connected with the high-power power supply and the system protection module. According to the application, the original working characteristic of only discharging is changed, the charging current is more stable, one Hall sensor can be used for collecting charging and discharging signals, the protection functions of preventing reverse connection of the positive electrode and the negative electrode of the battery, preventing overcurrent, preventing overvoltage, preventing overheating and the like are achieved, and the charging and discharging current is more stable and accurate.

Description

technical field [0001] The invention belongs to the field of battery charging and discharging, and in particular relates to an intelligent charging and discharging maintenance device and a control method for the entire life cycle of an energy storage battery. Background technique [0002] The energy storage battery is generally installed on the equipment as a backup or emergency power supply of the equipment. When the main power supply of the equipment fails to work normally, the energy storage battery starts to supply power to the key loads of the equipment to ensure the normal operation of the equipment. For example, the aviation battery is loaded on the aircraft as a kind of energy storage battery, and supplies power to the key loads of the aircraft when the aircraft is in an emergency state. Under normal circumstances, the main power supply of the aircraft works normally, and the equipment of the aircraft is powered by the main power supply; but when the main power suppl...
