[0048] Based on the structural schematic diagram of the above-mentioned charging system for automatically switching power of the present invention, the first embodiment of the charging system for automatically switching power of the present invention is proposed. In this embodiment,
[0049]The charging pile 10 is used to obtain the current power gear level, and determine the corresponding pulse signal according to the current power gear level;
[0050] It should be noted that the charging pile 10 can first obtain the current power gear level, and then determine the corresponding pulse signal according to the current power gear level, and the pulse signal is used to transmit the power corresponding to the current power gear level signal (such as a signal containing the pulse duty cycle corresponding to the current power gear level), the number of stages of the current power gear level can be determined according to actual needs, which is not limited in this embodiment, and the ...

The invention relates to the technical field of vehicle-mounted charging. The invention discloses a charging system and method capable of automatically switching power. The system comprises a chargingpile and a vehicle-mounted charger; the charging pile is used for obtaining a current power gear level. The charging pile is used for receiving the current power gear level and determining a corresponding pulse signal according to the current power gear level, the charging pile is further used for sending the pulse signal to the corresponding vehicle-mounted charger, and the vehicle-mounted charger is used for receiving the pulse signal, adjusting the current charging power according to the pulse signal and charging according to the adjusted current charging power. A corresponding pulse signal is sent to the vehicle-mounted charger through the charging pile according to the current power gear level, so that the vehicle-mounted charger automatically adjusts the current charging power according to the pulse signal to realize automatic switching of the vehicle-mounted charging power. Potential safety hazards existing in an existing alternating-current charging pile are avoided, chargingsafety and user experience are improved, and unnecessary energy waste is reduced.
Description
technical field [0001] The invention relates to the technical field of on-board charging, in particular to a charging system and method for automatically switching power. Background technique [0002] The existing AC charging piles are generally 2kW, and a small number of 3.5kW charging boxes are installed, which cannot meet the needs of vehicles equipped with 6kW on-board chargers. It is thinner and cannot match the power of the charging pile, which poses a safety hazard and is likely to cause unnecessary waste of resources during subsequent line transformation or vehicle upgrades. On the other hand, the charging circuit of the above-mentioned AC charging pile cannot realize the free switching of charging power because it cannot carry a large current, nor can it meet the charging needs of users who use high-power charging vehicles, and when the above-mentioned AC charging pile is disturbed, Charging failures may occur due to control pilot (Control Pilot, CP) voltage fluctu...
