The distinction between slow and rapid (or fast/ultra-rapid) charging is primarily based on charging power and the time required to regain range.
Slow charging typically uses Alternating Current (AC) charging stations, offering moderate power that allows the vehicle to be recharged over several hours, often overnight or during extended periods. It’s ideal for home charging of light vehicles or in locations where charging time is not a constraint.
Conversely, rapid charging, which utilizes Direct Current (DC) charging stations, allows for significant range recovery in under an hour. This type of charging is particularly well-suited for heavy-duty vehicles, long-distance journeys, and urgent charging needs.
