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.
When the battery is charged below then 80% you can use 20% of the battery's capacity (Ah) to recharge the battery but when the battery reached 80% State of charge gradually decrease the amps and voltage will stay the same between 12-12.7V (Depends on different manufacturers)
When the battery reaches its full charge cut-off voltage, constant voltage mode takes over, and there is a drop in the charging current. The charging current keeps coming down until it reaches below 0.05C. The battery reaches full charge voltage some time after the CV mode starts (as soon as one of the cells reaches its full charge voltage).
The battery reaches full charge voltage some time after the CV mode starts (as soon as one of the cells reaches its full charge voltage). At this stage, estimating SoC (state of charge) based on the battery voltage would mean that the battery is fully charged.
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.
(More on the other main lithium battery chemistry type, LFP, later). For longevity of EV batteries, it is considered best not to stress them unnecessarily by charging to 100% every time you plug-in. For today’s EV battery sizes, it is also completely unnecessary to charge to 100% on a regular basis.
