This utility model provides a bidirectional charging and discharging system for ship-shore use, relating to the field of ship energy supply technology. It includes a high-voltage input module, an AC power distribution module, a low-voltage power distribution module, an AC / DC conversion module, and cable equipment. The high-voltage input module connects to a shore-based AC power source, which is stepped down by a first transformer to supply power to the low-voltage power distribution module. The voltage is then stepped down by a second transformer and output as DC power via the AC / DC conversion module to charge the ship's energy storage unit. The AC / DC conversion module employs a bidirectional AC / DC conversion structure, enabling bidirectional power transmission between the ship and the shore-based power grid. The system uses a modular prefabricated structure, isolating the AC and DC side functional units to improve system integration and operational efficiency. It also ensures flexible switching between shore power supply and ship energy storage discharge during ship berthing, possessing excellent energy regulation capabilities and grid adaptability.

The application relates to the charging technical field and discloses a charging power distribution method and electronic equipment. The charging power distribution method comprises the following steps: acquiring pile charging demand information of each charging pile in a target charging group, the target charging group comprising at least two charging piles; determining group actual distribution power of the target charging group, the group actual distribution power being the highest power distributed to the target charging group; determining pile upper limit power of each charging pile in the target charging group; and determining pile actual distribution power of each charging pile according to the group actual distribution power, the pile charging demand information and the pile upper limit power. According to the charging demand of a charging vehicle, the output power of each charging pile can be flexibly adjusted, the charging demand of each charging vehicle can be maximally satisfied, meanwhile, the recovery and release of the redundant power among the charging piles can be realized, and the power utilization efficiency is improved.
