The core of an integrated photovoltaic storage and charging station consists of three parts - photovoltaic power generation, energy storage battery and charging pile. These three parts form a micro-network, using photovoltaic power generation, the power stored in the storage battery, when needed, the storage battery will be supplied to the charging pile to use, through the light storage charging system, solar energy, this clean energy is transferred to the car’s power battery for the vehicle to drive use.
According to the demand, the light storage and charging integrated charging station can realize two operation modes: grid-connected and off-grid. Light storage charging integrated charging station into the grid, in addition to accepting energy from the photovoltaic solar panels, storage batteries in the low price of electricity when charging, in the high price of electricity when discharging, reduce the cost of charging at the same time can be shaved to fill the valley, but also to make up for the shortcomings of the discontinuity of the solar power generation, and when the grid power outage, the light storage charging system can be used in off-grid mode of operation of new energy vehicles for emergency charging.
The advantages of optical storage charging integrated power station.
1. The use of renewable energy, environmental protection, no carbon emissions, help to achieve carbon neutrality.
2. It can use the energy storage system to store energy at night, and supply power to the charging station during the charging peak period through the energy storage power station and the power grid together, which not only realizes the peak shaving and filling in the valley, but also saves the cost of distribution capacity increase, and at the same time effectively solves the problems of new energy power generation intermittency and instability.
3. It can solve the problem of power distribution grid in limited land resources, and interact with the public power grid flexibly and operate relatively independently according to the needs, use new energy as much as possible, and alleviate the impact of charging pile power consumption on the power grid. In terms of energy consumption, the direct use of storage batteries to charge the power battery improves the energy conversion efficiency.
