Abstract

The invention discloses a battery detection and maintenance method and a battery detection and maintenance system. The battery detection and maintenance system comprises a matrix switch, a battery parameter detection circuit, a charge and discharge activation circuit, a desalination circuit, an alternating current-direct current constant-current electronic load circuit and a system failure simulation circuit. The battery detection and maintenance method comprises: correspondingly and automatically collecting the voltage and current signal and the variation thereof of a monomer battery (whole battery pack) during online constant-current charging and discharging so as to calculate the internal resistance, the SOC parameter and the SOH parameter of each monomer battery; according to the battery detection results, carrying out online pulse-variable charging and discharging activation treatment and ultrasonic wave standing wave desalination treatment on the monomer battery with poor performance; and finally carrying out overvoltage / undervoltage failure simulation, battery internal resistance failure simulation and SOC and SOH failure simulation on the monomer battery, and carrying out overvoltage / undervoltage failure simulation and open circuit failure simulation on the whole battery pack so as to judge whether the system has the failure. According to the present invention, with themethod and the system, the problem that the battery detection and maintenance is not perfect in the prior art can be solved.

Description

technical field [0001] The invention belongs to the fields of electric power system, communication, rail transit, UPS and electric vehicle, and in particular relates to a battery detection and maintenance method and system. Background technique [0002] With the development of smart grid and the continuous improvement of social intelligence, informatization and automation, people's dependence on power, communication, Internet, transportation, finance and other industries has further deepened, and more requirements have been put forward for the reliability of the power supply system. high demands. No matter in power substation, telecommunication room, data center, mobile base station, rail transit or UPS power system, the battery pack plays an extremely important role in the system as a backup DC power supply, and is an important equipment to ensure uninterrupted power supply and emergency use. It is the last insurance for the power supply system to maintain normal operation...
