Problems solved by technology
The charging time of the battery is long, the efficiency is low, and charging equipment must be installed, the initial investment is large, the efficiency of electricity consumption is low, and the transportation cost is high
In order to solve the problems of huge charging equipment, low charging quality efficiency, low energy efficiency conversion ratio, and poor battery life for mining battery electric locomotives, an integrated on-board charging and driving device is required to realize the integration of charging and discharging, reduce the use cost of electric locomotives, and improve work efficiency
[0003] Mining battery electric locomotive, due to the characteristics of the battery itself, is only suitable for constant current working mode. When the electric locomotive is started and accelerated, the battery is difficult to discharge with a large current instantaneously, so that the output torque of the driving motor is insufficient, and the high current discharge seriously affects the battery. life

The invention discloses a mine storage battery electric locomotive mounted charging and driving integrated circuit structure. The structure mainly comprises a storage battery, a supercapacitor, a first DC-DC converter, a second DC-DC converter, an inverter circuit and a driving motor; one end of the first DC-DC converter is connected with the storage battery in series, the other end of the first DC-DC converter is connected with the inverter circuit in parallel, one end of the second DC-DC converter is connected with the supercapacitor in series, the other end of the second DC-DC converter isconnected with the inverter circuit in parallel, and the output end of the inverter circuit is connected with the driving motor in series. When a mine storage battery electric locomotive is in the traction driving state, the storage battery and the supercapacitor supply power to the electric locomotive; when the mine storage battery electric locomotive is in the parking charging mode, the drivingmotor and the inverter circuit form a charging circuit of the electric locomotive. The problem that mine storage battery electric locomotive offline charging equipment is huge and low in charging efficiency is solved, and the mine electric locomotive charging and operation efficiency can be improved.
Description
technical field [0001] The invention relates to the technical fields of power electronics, electric transmission, and electric energy storage, in particular to an on-board charging and driving integrated circuit structure of a mining battery electric locomotive. Background technique [0002] Traditional mining electric locomotives use lead-acid batteries to store energy. The charging of the batteries is generally carried out offline in the underground electric locomotive charging room. Each electric locomotive must be equipped with 2-3 sets of battery packs. The battery charging time is long and the efficiency is low. Charging equipment must be installed, the initial investment is large, the power consumption efficiency is low, and the transportation cost is high. In order to solve the problems of huge charging equipment, low charging quality efficiency, low energy efficiency conversion ratio, and poor battery life for mining battery electric locomotives, an integrated on-bo...
