Embodiment Construction
[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0030] like Figure 1 to Figure 7 As shown, a series-parallel switching control device between battery packs includes a knob 1, the knob 1 is connected to a turntable 3 through a transmission mechanism 2, and a plurality of contact pieces 30 are arranged on the turntable 3, and the contact pieces 30 It is connected with at least two sets of battery terminals 4, and the series-parallel switching control device between the battery sets in the present invention can switch at least two sets of batteries in series and parallel, so that the series-connected battery sets are directly charged with the mains current, and the parallel-connected The battery pack supplies power to the electric vehicle, and the device can charge the battery without using an additional transformer. The ingenious design simplifies the battery charging procedure and reduces power loss.
