The locomotive-specific battery charger is an in-vehicle charging device that can be fixed on a train. The supplementary charging of the vehicle battery pack can be completed while the train is running.
It realizes step-up and step-down control by DC/DC conversion of the auxiliary voltage of the locomotive to achieve constant current and constant voltage charging mode. Does not affect the rating of the locomotive internal combustion engine auxiliary generator (referred to as: auxiliary) voltage, high efficiency output. It overcomes the shortcomings of the battery that is caused by the auxiliary auxiliary voltage directly charging the battery and the long-term undercharge and the sacrifice of the auxiliary voltage.
The constant current and constant voltage two-stage charging mode eliminates the need for manual duty and automatically completes the entire charging process without any danger of undercharging or overcharging, effectively extending battery life.
Main features and functions:
It adopts switching power supply circuit, which is small in size, light in weight, high in efficiency and long in life.
All components adopt imported industrial grade devices, the circuit design is optimized and reasonable, and the production process is strictly improved to ensure the reliability and stability of the machine.
It adopts the mature Buck---Boost Converter circuit topology technology, which is stable and reliable.
The charging conversion efficiency is high, generally more than 90%.
The unique control technology is adopted to make the buck-boost transition smooth.
Voltage mode, current mode dual loop control, stable operation.
The protection circuit is complete, each unit circuit is protected step by step, and the work is reliable.
The unique circuit layout and structure make the self-radiation small, do not interfere with other equipment of the locomotive, and have strong anti-interference ability and stable work.
When the charger is connected or disconnected, it does not affect the original working status of other equipment in the vehicle.
Two input power modes, easy to control: directly use the auxiliary output of the locomotive as the external power supply for the power supply.
Three working states, flexible operation:
Automatic: When the locomotive is running, the auxiliary output power is directly used as the input power of the charger, and the charger charges the battery. At this time, the auxiliary hair can supply power to the auxiliary circuit load at the same time. Does not increase the labor intensity of the staff.
Manual: When there is another external power supply, the charging function can still be completed. Especially suitable for locomotive maintenance and maintenance, when the internal combustion engine does not start, the power supply in the workshop maintenance warehouse can be directly connected to the charger to complete the supplementary charging of the locomotive battery pack.
Stop: When an abnormal situation occurs, disconnect the internal combustion engine auxiliary power supply and the charger, isolate the charger, stop charging, and restore the original line on the locomotive.
Specifications range: voltage DC2V-600V, current 1A-1500A, optional according to demand.
