What are the different types of chargers?
A. Fast chargers are founded on three base power technologies: ferroresonant, SCR (silicium controlled rectifier) and IGBT (insulated gate bipolar transistor). Conventional chargers are primarily based on ferroresonant and SCR technologies, each with their own limitations. A ferroresonant charger can usually only charge one battery voltage at a time which is a major concern in operating environments where there are vehicles with various voltages. SCR chargers can be multi-voltage, however, the wider the range of vehicle battery voltages, the poorer the power factor for the lower battery voltages. In comparison, the most recent IGBT chargers can safely charge at higher currents while still maintaining the control to respond to any abrupt reduction of power. AccelRate’s patented technologies can be integrated to work with any of the above.
