The invention provides direct current charging equipment and a charging method for an electric bicycle. The direct current charging equipment comprises a charging detection module and at least one voltage conversion module, when the charging detection module detects that the charging detection module is electrically connected with the direct-current micro-grid, the charging detection module is connected with the corresponding voltage conversion module and outputs a conduction signal; and the voltage conversion modules are connected with the electric bicycle, and after any voltage conversion module is connected with the charging detection module, the direct current input voltage of the direct current micro-grid is obtained in response to the conduction signal, voltage conversion is carried out, and target direct current voltage is output to charge a battery in the electric bicycle. Therefore, an original transistor is replaced by the GaN HEMT, the charging circuit is simplified, the sizes of electrical elements in the circuit are reduced, and the charging cost is effectively reduced.

    本发明提供了一种电动自行车直流充电设备和充电方法,设备包括充电检测模块和至少一个电压转换模块;当充电检测模块检测到与直流微网建立电连接时,连接对应的电压转换模块,并输出导通信号;电压转换模块与电动自行车连接,在任一个电压转换模块与充电检测模块建立连接后,响应导通信号,获取直流微网的直流输入电压并进行电压转换,输出目标直流电压,以对电动自行车内的电池进行充电。从而通过GaN HEMT替换原始的晶体管,并简化充电电路,减少电路中的电气元件的尺寸,有效降低充电成本。
