Constant voltage and constant current charging mode, automatically complete the whole charging process. The whole charging process is closer to the original characteristics of the battery, avoiding the problems of undercharging and overcharging of the battery caused by the original charging method of the locomotive, and effectively prolonging the service life of the battery. The locomotive battery charger does not need to be manually on duty when working, and it can be charged for a long time without the danger of overcharging.
Circuit characteristics
1. The circuit topology and technology of Buck---Boost Converter circuit that have been very mature are adopted to improve the reliability of the circuit.
2. Because the charger circuit works in the switching state, its conversion efficiency is high, and the efficiency is more than 90% during the whole working period, which does not affect the original working state of the locomotive DC generator and does not affect other equipment of the locomotive.
3. Adopt unique control technology to make the step-up and step-down transition smooth.
4. Voltage mode and current mode double loop control, more stable work.
5. The protection circuit is complete, and the circuit of each unit is protected step by step, so that the charger works more reliably.
6. The unique circuit layout and architecture make its own radiation small, do not interfere with other equipment of the locomotive, and at the same time have strong anti-interference ability and make its own work more stable.
