6 FAQs about [Current Voltage Battery Charging Principle]

How do you charge a battery?

There are three common methods of charging a battery: constant voltage, constant current and a combination of constant voltage/constant current with or without a smart charging circuit. Constant voltage allows the full current of the charger to flow into the battery until the power supply reaches its pre-set voltage.

What is the difference between constant current charging and constant voltage charging?

Constant current charging is a method of continuously charging a rechargeable battery at a constant current to prevent overcurrent charge conditions. Constant voltage charging is a method of charging at a constant voltage to prevent overcharging. The charging current is initially high then gradually decreases.

How many volts does a battery charger run?

The charger has its constant current set to 30 A. When first turned on, the battery pack voltage will typically be under 60 V, below the constant voltage setting, so the charger will run in constant current mode and deliver a steady 30 A to the battery pack.

How does a battery charge work?

During the charging process, an external power source is connected to the battery, and a voltage higher than the battery’s current state of charge (SoC) is applied. The charging circuitry controls the flow of current into the battery, regulating the voltage and current levels.

How does a battery charge cycle work?

The constant voltage portion of the charge cycle begins when the battery voltage sensed by the charger reaches 4.20V. At this point, the charger reduces the charging current as required to hold the sensed voltage constant at 4.2V, resulting in a current waveform that is shaped like an exponential decay.

What is the constant voltage setting in a battery charger?

The constant voltage setting in the charger is set to this voltage. The cell groups have a capacity of 60 Ah, and can charge at up to 5C, but I limit the charge current to 0.5C, just to keep the size and weight of the charger reasonable. The charger has its constant current set to 30 A.
