Description

Change of electricity control method, equipment and storage medium based on change of vehicle bottom height
Technical Field
The invention relates to the technical field of new energy power conversion control, in particular to a power conversion control method, equipment and storage medium based on the bottom height of a power conversion vehicle.
Background
The current power supply mode of the electric automobile mainly comprises two modes of direct charging type charging and quick-change type power conversion, and because of the limitation of charging time and place, many new energy electric automobiles currently gradually adopt a mode of quickly changing batteries for energy supply.
At present, the development of quick-change technology of small passenger cars is most mature, and batteries of the passenger cars are fixed on a chassis of the car, so that when a battery pack is replaced, special battery replacement equipment is required to be moved to the bottom of the car for battery disassembly or installation. Moreover, due to the small weight of the passenger car, the volume of the battery pack is relatively small, and the operability of battery replacement is very convenient.
However, for large vehicles, such as heavy trucks, the vehicle body and the cargo weight are large, resulting in a large vehicle requiring a high capacity of the battery pack, and a large enough capacity of electrical energy is necessary to support the large vehicle traveling for hundreds of kilometers. Therefore, in the prior art, large battery containers of a new energy series are fixed on a girder of a vehicle in a top hanging mode, and the battery containers are arranged close to a cab, so that larger potential safety hazards are brought to a driver and the vehicle in the driving process and the top hanging power change process; if the battery fails, the driver is directly injured. In addition, the lifting mode has high requirements on the place of the power exchange station, and the power exchange station is required to have a large enough area to execute the battery transferring and the battery storing of the lifting equipment, so that the station building cost is high.
Therefore, for large vehicles, there is a strong need for a safer and more reliable power conversion mode that is easy to popularize. For example, a chassis-type power conversion mode of a passenger car is adopted. In the chassis type power conversion mode, a power conversion device (or a power conversion trolley) needs to walk below a vehicle so as to take off an original battery pack on the chassis of the vehicle, and then a new battery pack is installed on the chassis of the vehicle. Based on this, when changing the chassis formula battery package to the vehicle such as heavy truck, because automobile body weight is huge, battery weight is also great, leads to current battery replacement dolly to be lower when taking off old battery package or installing new battery package, also causes the potential safety hazard easily, and in addition, to different vehicles, the battery replacement potential precision of battery replacement dolly is harder to control to influence the dismantlement and the installation of battery package, leads to the battery replacement system operation unstable, and even more can cause the battery replacement failure.
