The invention provides an ultra-high-speed charging pile and a charging method. The ultra-high-speed charging pile comprises a rectifying circuit, an energy storage inversion unit, a superconducting magnetic energy storage unit, a charging inversion unit, a control circuit and a charging circuit. The rectifying circuit is used for providing a direct-current power supply for the superconducting magnetic energy storage and charging circuit and providing output current data for the control circuit; the energy storage inversion unit is used for providing proper voltage and current for the superconducting magnetic energy storage unit to enable the energy storage of the superconducting magnetic energy storage unit to be normally carried out; the superconducting magnetic energy storage unit is used for switching to an energy storage state or a discharge state based on a control signal of the control circuit; the charging inversion unit is used for providing the stored electric energy to the charging circuit at a fixed voltage; the charging circuit is used for providing charging voltage for an external load; the control circuit is used for controlling the working state of the superconducting magnetic energy storage unit. Second-level fast charging is achieved, on one hand, the charging time is shortened, on the other hand, the situation that capacity expansion needs to be conducted on the transformer is avoided, and the production cost is effectively reduced.

    本发明提供了一种超高速充电桩和充电方法,包括:整流电路、储能逆变单元、超导磁储能单元、充电逆变单元、控制电路和充电电路;整流电路用于超导磁储能和充电电路提供直流电源以及为控制电路提供输出电流数据;储能逆变单元用于向超导磁储能单元提供合适的电压电流使超导磁储能单元的储能正常进行;超导磁储能单元用于基于控制电路的控制信号切换至储能状态或放电状态;充电逆变单元用于将储存的电能以固定的电压提供给充电电路;充电电路用于为外接负载提供充电电压;控制电路用于控制超导磁储能单元的工作状态。实现秒级快速充电,一方面减少了充电时间,另一方面避免了需要对变压器进行扩容的情况,有效的降低了生产成本。
