Problems solved by technology

[0002] At present, charging electric trains or electric vehicles are more and more widely used in daily life, which ensures our daily travel and also makes a great contribution to low-carbon environmental protection. The platform performs charging operations for trains, and the existing platforms mostly use rail-specific power grids for power transmission, which cannot use electricity for daily use, and the cost of this method is relatively high. In addition, the charging stations cannot effectively use new energy for corresponding Charging work, now, trams mostly use overhead catenary, ground third rail contact power supply and on-board energy storage device power supply
For the catenary power supply mode, when the vehicle is running, the pantograph is stretched out to contact the overhead cable for power supply. This power supply mode is technically mature and reliable, but due to the need to erect cable supports, it affects the urban landscape, and at the same time, the wires are exposed, so it is relatively safe. Low
The adopted third-rail power supply system is installed in contact with the collector shoe at the bottom of the vehicle and the third rail on the ground, which effectively solves the corresponding problems caused by the catenary power supply, but this type of system is complex and costly, and at the same time has great impact on the road. The conditions (drainage, cleaning, etc.) are demanding, and the requirements for municipal design and management are high
The on-board energy storage device can solve the problems caused by catenary and third rail power supply systems, but the use of on-board energy storage devices for full power supply has problems of large size and service life cycle

Abstract

The present invention proposes a control device for intelligent switching charging and energy storage charging of electric vehicles. The photovoltaic controller is connected to the power input end of the battery pack, one end of the transformer rectifier is connected to the mains, and the other end of the transformer rectifier is connected to the battery pack. The signal output end of the detection control unit is connected to the signal input end of the battery pack, the power output end of the battery pack is connected to the charging pile of the electric vehicle, and power is supplied to the battery pack through the photovoltaic controller and the transformer rectifier; the energy storage management control unit is used for the electric vehicle battery For power storage, the motor drive signal output end of the master control unit is connected to the motor drive unit, the inverter signal output end of the master control unit is connected to the inverter unit, and the energy storage management control signal output end of the master control unit is connected to the energy storage management control unit. While ensuring the normal operation of the vehicle, there is no need for overhead cables, no impact on the city appearance, safe and reliable; there is no special requirement for the use environment, the cost is low, and the maintenance is convenient.
