Description
Technical Field
[0001] The present invention relates to the technical field of new energy vehicles, and in particular to a high-efficiency light storage and charging method for a new energy mobile battery-swapping vehicle. Background Art
[0002] New energy vehicles are vehicles that use unconventional automotive fuels as their power source, or use conventional automotive fuels but adopt new on-board power devices. They have new technologies and new structures. At present, the new energy vehicles promoted and used in my country are mainly electric vehicles. The energy batteries of electric vehicles adopt a charging mode, but in the charging field, they face problems such as few charging piles, difficult charging, and long charging time, which bring inconvenience to car owners, thus restricting the development of China's new energy electric vehicles. The battery replacement mode is a solution for new energy electric vehicles to supplement energy.
[0003] New energy mobile battery swap vehicles can make charging stations mobile, and can rescue new energy vehicles that have broken down on the roadside due to low battery, providing protection for their use. However, battery swap vehicles can only transport on-board batteries and lack charging functions. After replacing a fully charged battery, they need to return to the charging station to charge the low-battery. If they encounter a low-battery new energy vehicle on the way back, they cannot be rescued, which can easily lead to complaints from car owners and bring resistance to the use and development of battery swap vehicles. In addition, frequent trips to and from charging stations waste time, delaying the best rescue opportunity. Summary of the invention

[0018] Preferably, in step S3, during charging using the solar panel, the illuminance is monitored in real time, and if the illuminance is less than 2000LUX, the solar power generation facility is turned off.
[0019] Preferably, in step S3, the calculation formula for the power generation of the solar panel is:
[0020] Ep=HA×S×K1×K2
[0021] Where: HA is the total solar radiation on the inclined surface, S is the area of the solar panel, K1 is the solar module conversion efficiency, and K2 is the comprehensive efficiency of the solar module system.
[0022] Preferably, in step S3, a daylight sensor is used to detect sunlight.
[0023] Preferably, in step S4, before testing the on-board batteries, the power levels of all on-board batteries are tested, and the on-board batteries with the largest power levels are charged preferentially.
[0024] Preferably, in step S4, during the process of charging the vehicle-mounted battery, the measured voltage value of the cable is detected in real time, and the difference between the reference voltage value of the vehicle-mounted battery and the measured voltage value is used as the bus offset, and the operating state of each energy storage element is controlled according to the offset and the preset state level. When the measured voltage value of the cable is low or too high, the charging connection of the cable is disconnected.
