How Does Dynamic Charging Work?

Dynamic charging automatically adjusts the EV charger's power based on the home's real-time energy usage. As household devices consume more power, the Tap sends messages to decrease the charger speed to avoid exceeding the total electrical capacity. When energy demand drops, the charger ramps up again. This ensures safe, efficient charging without overloading the system.

At low household power usage (about 20% of the home’s maximum capacity), the EV charger can use the max available energy. This allows it to operate at or near full speed since most of the capacity is unused by other appliances.

With medium energy usage (around 50% of the home’s total power capacity), more appliances are drawing power. The charger automatically slows down slightly to ensure the home doesn't exceed its total power limit, balancing energy distribution.

When the house is using more than 80% of its total energy capacity, there’s very little left for the charger. To prevent overloading the system, the charger reduces its speed significantly or may even pause temporarily. This automatic adjustment protects the home's electrical system.
