Problems solved by technology

But its charging effect is not ideal enough, the charging function is single, and there is no intelligent function, let alone realize network management
In addition, there are other problems in the existing chargers, for example: due to the vast territory of our country, the temperature difference is very large throughout the year.
During the charging process, if the temperature of the battery is too high and the temperature rise is too large, it will accelerate the failure of the effective material on the battery plate, or even fall off, directly affecting the life of the battery; The extent and discharge conditions may be inconsistent, so some battery packs may already be sufficient, and some battery packs may not be sufficient
If the sufficient battery continues to charge, it will not only waste electric energy, but also damage the battery.
If the insufficient battery stops charging, it will affect the operation of battery-powered equipment

Abstract

The present invention discloses a high-power intelligent charging machine and its charging method. Said charging machine includes controllable rectification circuit and control unit, also includes monitoring circuit, D/A conversion circuit, A/D conversion circuit and trigger circuit. Said invention adopts a current variable charging method, according to the detected quantity of electricity in theaccumulator, initially it uses heavy-current to charge, then progressively reduces current until the charged electric quantity is enough, the current can be reduced to zero, so that the charging operation can be automatically implemented according to predefined charging curve. Besides, said invented charging machine is intelligent, can greatly prolong life of accumulator, shorten charging time and can save energy.

Description

technical field [0001] The invention relates to a high-power intelligent charger, in particular to an intelligent universal high-power intelligent charger. Background technique [0002] High-power smart chargers are used to charge high-power batteries. High-power batteries are widely used, such as flatbed trucks and battery forklifts with high-power lead-acid batteries or cadmium-nickel batteries used in the internal loading and unloading of goods in railways, ports, and various warehouses. The use of rechargeable batteries as energy has the advantages of low cost, low noise and basically no pollution, and is very beneficial to environmental protection. Therefore, it is the preferred vehicle for internal loading and unloading and short-distance transportation in railways, industrial and mining enterprises, etc. widely. In addition, with the increasing awareness of environmental protection, it is foreseeable that electric vehicles will be vigorously promoted and applied in ...
