Abstract

The invention provides an optical storage charging and discharging detection system and a use method thereof. The optical storage charging and discharging detection system body is connected with an alternating current power grid, and the optical storage charging and discharging detection system body organically combines charging, discharging, electric vehicle battery detection, energy storage and photovoltaic, so that charging and discharging of the electric vehicle and the battery detection of the electric vehicle are realized, solar energy can be stored in an energy storage battery, and the energy storage battery discharges electricity to the electric vehicle or other loads of a power grid; or the solar energy can be directly supplied to the electric vehicle, or the solar energy is connected to the grid. A plurality of groups of power can be effectively and automatically distributed to any one port through the power automatic distribution unit PCU, a bidirectional AC / DC module is added to the functional module group, the reuse of a power supply is effectively improved, and power generation, power utilization and battery health degree detection of new energy are realized through organic combination of charging, discharging, electric vehicle battery detection, energy storage and photovoltaic.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to an optical storage charging and discharging inspection system and a method for using the same. Background technique [0002] Charging piles, energy storage, and photovoltaics are all mature products in the market. Generally, the three products are independent of each other, such as figure 1 As shown, the three are coupled at the AC grid. The energy storage battery is charged when the electricity price is low, and stores energy. When the electricity price peaks or there is demand, the stored energy is converted into alternating current through the DC / AC conversion module of the energy storage system and returned to the grid. After the energy returns to the grid, it can be directly supplied to electric vehicles or other loads through the AC / DC module of the charging pile. When photovoltaics have solar energy, they can be converted into alternating current through the DC...
