Solar photovoltaic (PV) charging of batteries was tested by using high efficiency crystalline and amorphous silicon PV modules to recharge lithium-ion battery modules. This testing was performed as a proof of concept for solar PV charging of batteries for electrically powered vehicles.
It is mainly used in manufacturing during production of the battery. Battery test equipment can also be used in R&D departments to study battery performance. One typical application of a BTS is to charge and discharge a one-cell lithium-ion battery. Considering the voltage drop in the cable, the voltage required to do this is 0V to 5V.
This testing was performed as a proof of concept for solar PV charging of batteries for electrically powered vehicles. The iron phosphate type lithium-ion batteries were safely charged to their maximum capacity and the thermal hazards associated with overcharging were avoided by the self-regulating design of the solar charging system.
The anode material/metal lithium button battery and the lithium-free positive material (such as MnO2, etc.)/ metal lithium button battery are first discharged to the lowest voltage window during the test, and then charged.
This high system efficiency was achieved by directly charging the battery from the PV system with no intervening electronics, and matching the PV maximum power point voltage to the battery charging voltage at the desired maximum state of charge for the battery.
The coupling of the PV and battery systems was optimized by matching the maximum power point voltage output of the PV system at the PV operating conditions to the maximum charge voltage of the battery. This maximized the solar energy to battery charge efficiency.
