This device is critical for protecting batteries from overcharging and over-discharging, thereby extending their service life and maintaining vehicle performance.

Converter: A converter is a device that converts alternating current (AC) to direct current (DC). In electric vehicles, converters are essential for adapting the form of energy available to power various electronic components. Since many devices, including batteries, operate on direct current, the converter ensures that energy from the power grid or other sources can be used effectively. Converters can also operate in the opposite direction, converting direct current generated by batteries into alternating current to power vehicle systems. Their efficiency and reliability are crucial to the optimal operation of electric vehicles.

Alternating Current (AC): Alternating current is a type of electric current in which the direction of electron flow changes periodically. It is the most commonly used type of current for power transmission and distribution in domestic and industrial networks because of its ability to be easily transformed into different voltages. Alternating current can be transported over long distances with minimal losses, making it ideal for power transmission. In buildings and homes, alternating current is used to power most electrical appliances. In the context of electric mobility, alternating current is generally delivered by charging infrastructure with a power rating of 22 kW or less.

Direct Current (DC): DC is a type of electric current in which the flow of electrons occurs in a constant direction. It is mainly used in electronic systems and batteries because it provides a stable and uniform flow of electricity. In electric vehicles, direct current is used to charge batteries and power the electric motor. It is delivered, generally, by charging infrastructures with a power rating greater than 22 kW. Unlike alternating current, direct current cannot be transported effectively over long distances without incurring significant energy losses. However, its stability makes it essential for powering sensitive devices such as computers and cell phones.
