Embodiment Construction
[0029] In the following, the present invention will be further described in conjunction with specific implementation methods. It should be noted that, on the premise of not conflicting, the various embodiments or technical features described below can be combined arbitrarily to form new embodiments.
[0030] A control method that can gradually increase the charging circuit topology of charging piles, including a control step and a charging step. In the control step, when the number of charging piles needs to be increased, the charging piles are connected to the reserved large The idle relay in the power relay centralized box is connected, and then the control part of the charging pile is connected to the area control box through the signal line.
[0031] Both the regional control box and the high-power relay centralized box are preset in the parking lot.
[0032] When the charging pile needs to be used, an instruction is sent to the relay through the regional control box, so t...
