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.
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.
Charge Voltage – The voltage that the battery is charged to when charged to full capacity. Charging schemes generally consist of a constant current charging until the battery voltage reaching the charge voltage, then constant voltage charging, allowing the charge current to taper until it is very small.
Opposite charges attract, and like charges repel (think of a magnet). Now let’s look at “charge” as it relates to a battery. When you connect a wire conductor between the positive (cathode) and negative (anode) terminals of a battery, one end of the wire is positively charged, and the other end of the wire gets negatively charged.
Charging voltage = OCV + (R I x Battery charging current limit) Here, R I is considered as 0.2 Ohm. Observing the below picture, it becomes evident that the DC power source regulates its charging voltage in accordance with the charging current limit.
(Recommended) Charge Current – The ideal current at which the battery is initially charged (to roughly 70 percent SOC) under constant charging scheme before transitioning into constant voltage charging. (Maximum) Internal Resistance – The resistance within the battery, generally different for charging and discharging.
