During the charging process, some of the lithium ions in the lithium iron phosphate are extracted, transferred to the negative electrode through the electrolyte, and embedded in the negative electrode carbon material; at the same time, electrons are released from the positive electrode and reach the negative electrode from the external circuit to maintain the balance of the chemical reaction.1. Stabilize the power grid: Suppress the short-term impact of the microgrid, so that the microgrid can run stably in the grid-connected/isolated grid mode;Provide short-term stable power supply. 2. Improve power quality and increase the economic benefits of microgrids.Our battery all use cut aluminum case,can keep safe and anti-shock.all battery within battery management system(BMS) and MPPT controller(Optional).
