This charging system should be adjustable for battery bank size and type and can charge Lead Acid and Lithium-ion batteries. This smart small inverter should be suitable for solar panels, a built-in high-performance maximum power point tracking (MPPT) function to effectively capture and collect sunlight. The EV port is designed to be isolated and bidirectional so that both charging and vehicle-to-grid can be implemented. As PV and EV are both DC by nature, the converter uses a central DC link to exchange power between the EV and PV, thereby increasing efficiency. The closed-loop control allows four different power flows: PV EV, EV grid, grid EV, and PV grid. Therefore, the converter operates as a PV inverter, a bidirectional EV charger, and a combination of both. The primary purpose of the control for the PV IBC, EV IBFC, and grid inverter is MPPT, control of EV charging, and power balance, respectively. This system should abide by at least one DC charging standard.
