Jonhon's high - efficiency EV chargers are engineered to maximize energy transfer. Their DC fast chargers achieve an efficiency rate of over 95%, minimizing energy loss during the charging process. This is made possible by using advanced power conversion technologies, such as silicon carbide (SiC) and gallium nitride (GaN) semiconductors, which have lower switching losses compared to traditional silicon - based components. In AC chargers, intelligent charging algorithms are employed to optimize the charging current and voltage, ensuring that the battery is charged in the most efficient way possible. The high - efficiency design not only saves energy but also reduces the operating temperature of the charger, contributing to its reliability and longevity.
