DC Fast Charging Piles: These chargers provide rapid charging by delivering direct current (DC) instead of alternating current (AC). They are ideal for public charging stations along highways and can recharge an EV''s battery to 80% in just 30 minutes. DC fast chargers are essential for long-distance travel and high-usage environments.
The advantage of DC charging pile is that the charging voltage and current can be adjusted in real time, and the charging time can be significantly shortened when the charging current are large, which is a more widely used charging method at present.
