Selecting the right EV charging solution with Jonhon involves evaluating power needs (AC vs. DC, kW rating), installation environment (indoor/outdoor, public/residential), and compatibility (vehicle charging standards). Key factors include charging speed, safety certifications (UL, CE, GB/T), network connectivity (for smart charging), and after-sales support. For fleets, high-power DC chargers with multiple ports are ideal, while homes may need compact AC wall boxes. Consider future scalability (e.g., 1000V readiness) and energy management features for long-term value.
