The high level of load balancing on our charging systems is unique and makes Ecotap distinctive in the market. An Ecotap charger can be of service in almost any situation and prevents unnecessary, expensive and time-consuming grid expansions. Moreover, we believe that effective division (balancing) can lead to optimal multiplication (expansion). The installation of additional Ecotap charging stations can therefore often be made possible in a very price-efficient way.
Below we explain which levels of balancing are possible. Are you curious about how we can install the best charging infrastructure for your specific situation? Then contact one of our sellers. Using the balancing software is free.
All Ecotap charging systems are suitable to deliver 22 kW per charging point. However, this amount of power is not always present and it is necessary to distribute power. For example, if only 22 kW (32A) is available and 2 cars want to charge, then we divide the 22 kW over 2 cars so that they can both charge at 11 kW (16A). As soon as 1 car leaves or is full, the available power is automatically returned to the other car, which can then continue charging at maximum power.
When several charging points (for example 3 charging systems with 6 charging points) are connected to the same installation group, we can distribute this fixed power of, for example, 66 kW (± 100A) over the charging cars. If 6 cars are charging at the same time, the power is divided between these 6 cars and they all receive 11 kW. When 3 cars leave or are full, all cars can recharge at maximum power.
Finally, we can also combine the previous balancing method with a fluctuating amount of available energy. If in the previous example the total available energy of 100A is also intended for other appliances / buildings, it will not always be fully available to the cars. The combined capacity of the charging stations is limited to 100A. By placing an extra meter (Loadbalancer) at the main power supply that measures the consumption in the building, it is calculated 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 it. When no energy is consumed in the building, the charging stations can distribute 100A, as explained above.
When the building itself also needs power (for example 20A), only 80A (± 55 kW) is distributed over the charging systems, so that 13A (± 9 kW) can be used for 6 charging cars.
Finally, we also incorporate a phase shift in the Ecotap Duo charging systems, which means that two single phase charging vehicles never use the same phase. In that case, cars do not need to be balanced, because detection takes place in the system.
An additional advantage is that your car charges faster.
