Embodiment 1
[0050] The invention provides a charging unit of an electric vehicle changing station, which is used to charge a quick-change battery of an electric vehicle, such as figure 2 As shown, the charging unit 2 forms a charging space, including a charger 202 and an electrical connection base 204 located in the charging space. The charger 202 includes a DC output interface, and the DC output interface is electrically connected to the electrical connection base 204; the electrical connection base 204 It includes a high-voltage pole for realizing electrical connection with the quick-change battery 203 .
[0051] Wherein, when the fast charging battery 203 is inserted on the electrical connection base 204, fast charging can be realized through the high-voltage pole, 201 represents a DC wire, and the DC output interface of the charger 202 is connected to the DC input of the electrical connection base 204 through the DC wire 201. Interface connection, so that the charger 202 can provide ...
Embodiment 2
[0056] This embodiment is a further improvement on the basis of embodiment 1, such as image 3 As shown, the charger 202 also includes a first communication interface, and the first communication interface communicates with the electrical connection base 204 through the communication cable 206. communication connection.
[0057] Wherein, in the charging unit 2 in this embodiment, the charger 202 includes an AC input interface for connecting an external AC power supply, wherein the AC power supply is connected to the charger 202 through the AC wire 205, and the external AC power supply is connected to the charger through the AC wire 205. 202 for power.
[0058] It should be understood that, in the charging unit 2 , the charger 202 and the electrical connection base 204 are directly connected through the charging DC wire 201 , and each charging unit 2 provides an AC input interface externally, and receives AC power through the AC wire 205 .
[0059] Wherein, the charger 202 al...
Embodiment 3
[0065] This embodiment provides an electric vehicle power station, Figure 4 A schematic diagram of some modules of the electric vehicle swapping station in this embodiment is shown. Such as Figure 4 As shown, the electric vehicle swapping station in this embodiment includes several charging units 2 in Embodiment 2.
[0066] Wherein, the electric vehicle replacement station includes a charging stand 30 , and the charging units 2 are arranged in a matrix on the charging stand 30 .
[0067] Wherein, the charging rack 30 includes a plurality of horizontal frames and vertical frames arranged at intervals, and the horizontal frames constitute the upper and lower racks of the battery holder in the charging space. The horizontal frame, for the upper charging unit, the horizontal frame is the lower frame, and for the lower charging unit, the horizontal frame is the upper frame. Figure 4 It shows a schematic installation method in which the charger is arranged at the lower end of ...
