Host and backup intelligent storage battery charger

Abstract

The invention discloses a host and backup intelligent storage battery charger and belongs to the technical field of charging of storage batteries. The problem that the function of a traditional storage battery charger is single is solved. The host and backup intelligent storage battery charger mainly comprises a host and backup switching circuit unit, a load and at least one charger unit. Each charger unit comprises a charging and discharging circuit module, a 485 communication module, an alarming and alarming dry point output module and a work state display and state display dry point output module. The host and backup intelligent storage battery charger is ingenious in design and comprehensive in function, economic loss caused when a main charger breaks down is effectively avoided, practicability is high, implementation cost is low, and the host and backup intelligent storage battery charger can be widely applied to railway, civil aviation, communication and electric power enterprises where lots of maintenance-free lead-acid storage batteries are used.

Description

technical field [0001] The invention belongs to the technical field of accumulator charging, and in particular relates to a primary and backup intelligent accumulator charger. Background technique [0002] The battery charger organically combines high-frequency switching power supply technology with embedded microcomputer control technology, and uses advanced intelligent dynamic adjustment technology to optimize the charging characteristic curve and effectively prolong the service life of the battery. It adopts constant current / W stage / constant voltage / small constant current four-stage charging method, which has the characteristics of high charging efficiency, high reliability, easy operation, light weight, small size, etc., and is widely used in railways, civil aviation, communications, electric power Companies that use a large number of maintenance-free lead-acid batteries. Even so, there are still deficiencies in traditional battery chargers, which are specifically refle...

AI Technical Summary

Problems solved by technology

Even so, there are still deficiencies in traditional battery chargers, which are specifically reflected in the following: 1. Traditional battery chargers operate on a single machine, with only one charging unit. When the charging unit fails, the entire product will not be able to work. Cause serious economic losses; 2. The traditional battery charger cannot realize the remote video monitoring function, and cannot meet the requirements of the battery charger function in today's era; 3. The traditional battery charger has no alarm dry point output and no working status display dry point output function , requires staff to be on duty and guards on site, which is a serious waste of human resources
