Technical Requirements for EV Charging Stations

Technical Design Checklist for EV Charging

Building a charging station requires rigorous compliance with electrical engineering standards.

Key Electrical Components:

• Dedicated Transformer: Required if total station capacity exceeds 50-100 kW.
• Earthing System: Neutral-earth voltage must be strictly under 1-2V to prevent damage to EV chargers and car onboard electronics.
• Protective Switchgear: Surge protection devices, over-current, under-voltage, and residual current devices (RCD Type B).
