The charger manufacturer realizes the optimized Wsa+Pulse charging characteristic curve through the microcomputer control technology, and the charging current automatically decreases with the increase of the charging voltage of the battery; combined with the pulse charging method at the end of charging, the charging effect is more ideal. The principle of capacity balance is used to intelligently judge the sufficiency of the battery to ensure that the battery is sufficient-that is, neither undercharge nor overcharge. The charging has the function of dynamic tracking and adjustment of charging parameters and perfect protection.
· Adopt the principle of capacity balance to intelligently judge the sufficiency of the battery;
· Under the premise of ensuring sufficient battery power, it can greatly reduce the internal temperature and gas evolution of the battery during the charging process, and effectively extend the charge and discharge cycle life of the battery pack;
· High-brightness LED indicates the operating status of the charger;
· Display battery voltage, power supply voltage, charging current, capacity, time and other parameter information, and fault code displays fault content;
· With open circuit, reverse fault protection and alarm functions;
· With overload and short-circuit fault protection and alarm functions;
· It has fault protection and alarm functions such as transformer over-temperature and module over-temperature;
· With functions of automatic detection, delayed start, and soft start;
· With manual or automatic equalizing charging function to ensure the consistency of battery cell capacity;
· With automatic initial charging function;
· With desulfurization charging function;
· Unplug the charging plug during charging, the charger will automatically shut down.
The characteristics of the industrial frequency machine are simple, and the existing problems are:
1) Large input and output transformer size;
2) The size of the output filter used to eliminate high-order harmonics is large;
3) Transformers and inductors produce audio noise;
4) The dynamic response performance to load and mains changes is poor.
5) Low efficiency;
6) The input has no power factor correction, which causes serious pollution to the grid;
7) The cost is high, especially for small-capacity models, which cannot be compared with high-frequency machines.
