Description

technical field [0001] The invention relates to the technical field of communication and power distribution automation terminal equipment, in particular to a remote control battery charging and discharging device. Background technique [0002] Remote charging and discharging technology is a technology that realizes multiple functions such as remote charging and discharging operations on battery packs and remote control and setting of charger status. The remote charging and discharging technology realizes the remote capacity discharge and charging test of the battery pack, the remote test of the internal resistance of the battery, the remote control of the DC bus state switching, the remote control of the charger’s equalization / float charging status, and the remote setting of the charger’s parameters. It requires a lot of manpower and material resources and personnel must go to the site to operate, which fundamentally reduces the workload of communication power supply mainten...

AI Technical Summary

Problems solved by technology

[0003] The traditional battery remote charging and discharging system, through the control host to remotely control the charging and discharging control mechanism for charging and discharging, can only be controlled by the control host in the control room. When the personnel go out, it is not convenient for the person in charge of the equipment to know the equipment situation and control the operation in time.

Moreover, when the internal resistance of the battery is abnormal, the battery cannot be balanced and activated in time.

Moreover, when the battery fails, some of the batteries have problems, which may have a fatal impact on the entire battery pack, and the entire battery pack is likely to stop operating collectively, causing a large area of ​​battery packs to be paralyzed.
