Automatic charging discharging controller for accumulator

Abstract

The invention discloses an automatic charging and discharging controller for a storage battery. The automatic charging and discharging controller is characterized by comprising a CPU controlling unit, the CPU controlling unit is respectively connected with a current detection device, a voltage detection device, an alternating-current switching device, an alternating-current power supply detectiondevice, a clock display device and a miniature printer, wherein, the power supply part supplies power for the devices above, the direct current detection device is connected with a current and voltage conversion module, the current and voltage conversion module is connected with an ADC0804 analog-digital conversion module through a signal switching switch, and the ADC0804 analog-digital conversion module is connected with a P2 interface of a 89C51 controller. Compared with the prior art, the invention can automatically and manually perform charring and discharging to the storage battery, record the charring and the discharging data and can judge the property of the storage battery.

Description

technical field [0001] The invention belongs to the technical field of automatic charging and discharging of storage batteries, and in particular relates to a charging controller for automatic discharging of storage batteries. Background technique: [0002] At present, the battery is used as the backup power supply of the communication system, and its application is becoming more and more popular. In the case of power supply interruptions such as emergency emergencies and natural disasters, its role is becoming more and more important, because the normal operation of communication equipment cannot be separated from the power supply. The supply of blood is just like the blood circulation that people cannot do without. However, it is not easy to judge whether the performance of the battery is good or not, and the maintenance of the battery is also troublesome. The maintenance depends on the power supply maintenance professionals to take the bulky discharge instrument to the c...

Problems solved by technology

However, it is not easy to judge whether the performance of the battery is good or not, and the maintenance of the battery is also troublesome.

The maintenance depends on the power supply maintenance professionals to take the heavy discharge instrument to the communication room, because some batteries have a large capacity and the battery packs are scattered, so the maintenance of a communication station can be as little as one day, and as many as two days; all communication stations need one at a time. It took many months, and the maintenance personnel traveled long distances, went through bumpy roads, moved instruments, made records, etc., and the labor intensity was very high
