Loadbalancing
High-level load balancing on all our systems.The high level of load balancing on our charging systems is unique and sets Ecotap apart in the market. An Ecotap charger can serve you in almost any situation and prevents unnecessary, expensive and time-consuming grid extensions. Using the balancing software free of charge. Below, we explain which levels of balancing are possible. Curious about the possibilities for your location?
Load balancing between two charge points
(on 1 charging system)
All Ecotap charging systems are capable of delivering 22 kW per charging station. However, this amount of power is not always available and it is necessary to distribute power. For example, if only 22 kW (32A) is available and 2 cars want to charge, we divide the 22 kW between 2 cars so that they can both charge on 11 kW (16A). As soon as 1 car leaves or 1 is full, the available power is automatically returned to the other car, which can then continue charging at maximum power.
Load balancing between multiple charging stations
(multiple charging systems)
When multiple charging stations (e.g. 3 charging systems with 6 charging stations) are connected to the same installation group, we can distribute this fixed power of, say, 66 kW (± 100A) over the charging cars. If 6 cars are charging at the same time, the power will be divided among these 6 cars and they will all get 11 kW. When 3 cars leave or are full, all cars can charge at maximum power again.
Dynamic load balancing
Furthermore, we can also combine the previous balancing method with a fluctuating amount of available energy. In the previous example, if the total available energy of 100A is also meant for other devices/buildings, it will not always be fully available to the cars. The combined capacity of the charging stations will be capped at 100A. Placing an additional meter (Load balancer) at the main power supply that measures the consumption in the building will calculate how much power is available for the charging stations. For example, a building has a 100A network connection and 3 charging systems are connected to this. At the time when no energy is consumed in the building, the charging stations can distribute 100A, as explained above.
The moment the building itself also needs power (e.g. 20A), only 80A (±55 kW) is distributed among the charging systems, which means that, with 6 charging cars, 13A (±9 kW) may be used each.
Phase rotation
The Ecotap Duo charging systems also work with phase rotation. Which means that two single-phase charging vehicles never use the same phase. In this case, cars do not need to be balanced because detection takes place in the system. An additional advantage is that your car charges faster.
