Why is my EV charger not charging at full power?

It's perfectly normal for EV chargers to start off slow and then ramp up to their maximum power output. This is to protect the vehicle batteries. Once they reach about 80% charged, they'll slow down a bit. 

Some vehicles have their own limits on how much power they can take in. For specific details, check out your vehicle's manual. 

The health and capacity of your battery can also influence charging speed. For more details, refer to your vehicle’s manual. 

Hybrid vehicles have their own charging limits, typically up to 3kW. Some models may not hit the full 3kW. Your vehicle's manual will have all the specifics. 

If there's high demand for power in your property, the EV charger will alter its output to protect your home. This is called load balancing.
