With the rise of electric vehicles, the right EV charger boosts charging speed and battery lifespan. Yet, many are overwhelmed by "current," "voltage," and "power" specs. Understanding these three core parameters helps match chargers to your needs. This article breaks down the basics, recommends products by usage, and simplifies EV charger selection.
📚Understand Core Parameters: Current, Voltage & Power
The efficiency of an EV charger is determined by current, voltage, and power. The relationship among them is P = U × I. However, it is limited by the battery protection system, so the power cannot exceed the vehicle's maximum withstand power. For example, a 120kW charger theoretically outputs 120kWh per hour. But when the vehicle only supports 60kW, the actual charging power can only reach 60kW.
🧑🏭Classify by Parameter Requirements to Match Your Vehicle Usage Scenario
EV chargers can be categorized into three levels based on voltage, current, and power combinations, catering to different usage scenarios and vehicle needs:
🏠Level 1: Household Slow Charging
📒Working Principle:
Uses single-phase AC, with on-board charger converting it to DC. Suitable for low-load home use, gentle on the battery.
Solar chargers use MPPT for optimized power conversion, with energy storage integration.

III. Guide to Avoiding Pitfalls in Purchase: 3 Key Reminders
🧑🔧Match Charger to Vehicle: Check your vehicle's "maximum acceptable power" and charging port type before purchasing a charger. Mismatching power can lead to wasted costs or slow charging. 🤔Consider Installation Voltage: Opt for 220V single-phase power for home use and 380V three-phase power for commercial settings. Ensure your wiring can handle the load; a 7kW home charger typically requires 4mm² or thicker wires. 🔐Seek Smart Safety Features: Select chargers with over-temperature, leakage, and lightning protection to safeguard your equipment and ensure safe charging.
In short, prioritize matching EV charger voltage, current, and power to your vehicle's specs, usage scenarios, and habits, rather than chasing higher power.
