As the State of Charge (SOC) increases, the battery charging current limit decreases in steps. Additionally, we observe that the battery voltage increases linearly with SOC. Here, Open Circuit Voltage (OCV) = V Terminal when no load is connected to the battery. Battery Maximum Voltage Limit = OCV at the 100% SOC (full charge) = 400 V.
The constant voltage charging method uses a fixed voltage source to charge batteries. Its advantages include a simple circuit structure and easy control circuit design. In this mode, the charging current decreases as the battery approaches full charge.
A high charging current from 15 percent to 80 percent SOC provides fast charging, butthe high current stresses the battery and can cause battery lattice collapse and pole breaking. The main challenge for CV charging is selecting a proper voltage value that will balance the charging speed, electrolyte decomposition, and capacity utilization.
Under and over discharge protection, setting of the battery voltage and current profiles, and implementing battery charging control techniques can be achieved by using an appropriate control system. Conventional configurations for battery charging circuits, explained before, can be used for the battery charger. Inductive contactless charger scheme
Charging is the process of replenishing the battery energy in a controlled manner. To charge a battery, a DC power source with a voltage higher than the battery, along with a current regulation mechanism, is required. To ensure the efficient and safe charging of batteries, it is crucial to understand the various charging modes.
In other words, charging Lithium-ion batteries requires a set current limit ranging until it is completely charged. The charge circuitry changes to the constant voltage mode when the battery reaches its final voltage.
