As shown in fig. 8, in this embodiment, the bus ring power generation is taken as an example, and the charging control principle is as follows:
In the process of generating electricity by the reverse dragging of the motor, alternating current is converted into direct current through the motor controller and is stored in the high-voltage battery pack. When the charge controller acquires that the signal of the electric quantity stored in the high-voltage battery pack is lower than a certain threshold value (set to be 20-30%) through pins 1 and 2, the charge controller sends out 12V signals through pins 5 and 6 to control the IR1 of the high-voltage relay to suck, the vehicle-mounted generator generates electricity to charge the vehicle-mounted starting battery and supply electricity for the whole vehicle, at the moment, pins 3 and 4 of the charge controller have no signals, namely the DC-DC does not have the 12V signal and does not work, and the high-voltage battery pack does not charge the starting battery.
When the charge controller collects the electricity storage quantity signals of the high-voltage battery pack through the pins 1 and 2 and reaches a certain threshold value (set to be 50-60%), the charge controller cancels the 12V signals provided by the pins 5 and 6, the IR1 of the high-voltage relay is disconnected, and the generator does not work.

In this embodiment, the generator is preferably a torque generator, which is a three-phase ac permanent magnet generator with a model number of NE-300W, and a constant rotation speed is set for the generator (i.e. the transmission shaft 14 has a constant rotation speed), so that a plurality of power generation driving modules B can be ensured to simultaneously apply work to the transmission shaft 14 in an energy superposition manner.
As shown in fig. 9, in this embodiment, the subway handle is taken as an example to generate power, and the charging control principle is as follows:
When the power supply controller acquires that the signal of the electric storage capacity of the 12V battery pack is lower than a certain threshold value (set to be 20-30%) through pins 5 and 6, the power supply controller sends out a 12V signal through pins 3 and 4 to control the IR1 of the high-voltage relay to attract, an original vehicle low-voltage power supply system supplies power to the electric equipment of the carriage, at the moment, the pins 1 and 2 of the power supply controller have no 12V signal, the IR2 of the high-voltage relay is still in a disconnected state, the 12V battery pack and the electric equipment loop of the carriage are in a disconnected state, and the 12V battery.
when the power supply controller acquires the power storage quantity signal of the 12V battery pack through the pins 5 and 6 and reaches a certain threshold (50-60% is set), the pins 1 and 2 of the power supply controller provide the 12V signal, the high-voltage relay IR2 is attracted, the 12V battery pack and the carriage power utilization equipment loop are in a connected state, then the power supply controller cancels the 12V signal provided by the pins 3 and 4, the high-voltage relay IR1 is disconnected, and the original vehicle low-voltage power supply system does not supply power to the carriage power utilization equipment and supplies power by the 12V battery pack.
the 12V low-voltage direct current motor is selected, the motor reversely drives to generate electricity, alternating current is converted into direct current through the motor controller, and the direct current is used for directly charging the 12V battery pack. The electric quantity signal of the 12V battery pack is collected and judged by the power controller, and an algorithm that the charging controller controls the handrail power generation device to be alternately applied with the original vehicle low-voltage power supply system is established by controlling the suction and disconnection of the relays IR1 and IR2, so that the alternate application of the power supply of the electric equipment of the carriage is realized, the power supply frequency of the original vehicle low-voltage power supply system is reduced, and the effects of energy conservation and emission reduction are achieved.
Finally, it should be noted that the above description is only a preferred embodiment of the present invention, and those skilled in the art can make various similar representations without departing from the spirit and the scope of the present invention.
