One-machine six-mode fully-integrated direct current pile power distribution device

Abstract

The invention discloses a one-machine six-mode fully-integrated direct current pile power distribution device. The power distribution device comprises a power cabinet and a charging terminal; a powermodule A, a power module B and a power module C are arranged inside the power cabinet, and the charging terminal consists of a charging terminal A, a charging terminal B and a charging terminal C; thecharging terminal A is electrically connected with a charge gun A01 and a charge gun A02 through a cable, the charging terminal B is electrically connected with a charge gun B01 and a charge gun B02through a cable, the charging terminal C is electrically connected with a charge gun C01 and a charge gun C02 through a cable, the power module A is electrically connected with the charging terminal Athrough a circuit A, the power module B is electrically connected with the charging terminal B through a circuit B, the power module C is composed of a power module C1 and a power module C2, the power module C1 is electrically connected with the charging terminal C through a circuit C1, and the power module C2 is electrically connected with the charging terminal C through a circuit C2. Six working modes can be achieved through the power distribution device, and the complexity of a system and the cost of equipment are effectively reduced.

Description

technical field [0001] The invention relates to a power distribution device, in particular to a one-machine six-full-body DC pile power distribution device, which belongs to the technical field of charging piles. Background technique [0002] At present, most of the DC charging piles with one machine and multiple chargers on the market use half-matrix or full-matrix switch arrays to realize the power adjustment of each charging gun, especially when there are many charging terminals and higher requirements for power adjustment. When using 10kW / 15kW as the base, the switch array will be very large. For example, for a 120kW power distribution unit with one machine and four guns, the switch array needs at least 32 DC contactors (excluding the discharge circuit), and the installation space The requirements are large, and the wiring and control are relatively complicated, especially in terms of control logic, because there are many output modes, the control logic is very complicat...

[0002] At present, most of the DC charging piles with one machine and multiple chargers on the market use half-matrix or full-matrix switch arrays to realize the power adjustment of each charging gun, especially when there are many charging terminals and higher requirements for power adjustment. When using 10kW / 15kW as the base, the switch array will be very large. For example, for a 120kW power distribution unit with one machine and four guns, the switch array needs at least 32 DC contactors (excluding the discharge circuit), and the installation space The requirements are large, and the wiring and control are relatively complicated, especially in terms of control logic, because there are many output modes, the control logic is very complicated, and the probability of failure is high during charging control, especially when one of the contactors fails. , if the protection logic is not strict, it will cause a great security risk
