概述
As an energy storage and grid interaction terminal, new energy charging piles are highly susceptible to DC leakage and mains over/under voltage faults due to their mixed AC/DC power supply circuits. They also require timed start/stop charging management, necessitating stringent safety protection standards.
Rynova has developed a complete set of protection and control chips specifically for charging pile scenarios. Its fluxgate-type Type B leakage protection solution accurately captures residual AC/DC current, its over/under voltage chip monitors the grid voltage in real time, and its timing IC enables scheduled charging. Fully compliant with IEC61851 and GB/T40820 charging pile standards, these chips eliminate equipment and personal safety risks caused by leakage and voltage anomalies.
