EV Charger =  voltage + Charging standard + power (For example: 3-Phase + Type 2 + 11KW)

Before purchasing, you need to know these knowledge

1. Power Type

• 1 Phase: 230V
• 3 Phase: 380V

2. Car charging port type

• Type 1 / Type 2

3. Power

• 3.5KW —— 16A  1-phase
• 7KW —— 32A  1-phase
• 11KW —— 16A  3-phase
• 22KW —— 32A  3-phase

Note: Currently, AC charger only distinguishes 4 power types.

3. Charging time = car battery capacity / power

• 1 phase power=230*current
• 3 phase power=380*current*1.732

What do I need to consider before choose a charger?

• Whether your car charging port is Type1 or Type2

•  Does your car support 3-phase power supply?

• What is the maximum power and current supported by your car? Check car description or ask factory
• How long do you want to fully charge

Selection method

• Higher charging power, faster charging speed
• If your car supports 3-phase, you can choose 3-phase and 1-phase charger. If your car don't support 3-phase, you must choose 1-phase charger
• Car charging power ≥ charger power. For example, the charger maximum power is 11KW, and your car maximum charging power is 9KW. When charging, the maximum power will be 9KW.
•  Home current ≥ charger power. For example, home current is 10A, and charger current is 16A. When charging, its maximum current is 10A (not exceeding home current )
