With Load Balancing, You Can Charge Several Electric Cars at a Time Whilst also Saving Money – even When the Connection Capacity is Limited.

Mehrere Elektroautos gleichzeitig laden mit einem Lastmanagement

Charge Multiple Electric Cars

Load balancing enables you to install multiple charging stations for electric cars with a consistent connection capacity1. In this process, the charging power is distributed equally across all electric cars to be charged.

Significant Cost Savings

Load balancing means you can avoid cost-intensive, one-off increases in connection capacity and prevent peak loads that result in a higher annual demand rate2.

Dynamisches Lastmanagement für Ladestationen ist flexibel erweiterbar

Flexible Extension Options

Dynamic load balancing enables you, at any time, to add additional electric car charging stations to your car park, and integrate them into the existing system at low cost.

Integriertes Lastmanagement in Ladestationen für Elektroautos

Integrated Load Balancing

A double charging station with integrated load balancing is able to distribute the total charging power equally between two electric cars. If only one electric car is plugged in, it charges with the full charging capacity (e.g. 22 kW). If two electric cars are plugged in, the charging power is halved accordingly (e.g. 11 kW per electric car).

Statisches Lastmanagement für Ladestationen

Static Load Balancing

With static load balancing, a reserved charging power that is fixed for all charging stations is distributed equally between several stations as soon as multiple electric cars are connected, and you can choose how many charging stations with the relevant output are integrated into the system.

Dynamisches Lastmanagement für Ladestationen

Dynamic Load Balancing

The total charging power available to the charging stations is dynamically adjusted to the current power consumption throughout the building, and distributed equally between the charging stations. As soon as you reach peak loads, the charging power is automatically reduced, and you choose how many charging stations with the relevant output are integrated into the system.

Take a Look at Our Practical Examples and Find Out How You Can Benefit from Dynamic Load Balancing

Hotel Alpenstern has 100 rooms and would like to provide its guests with ten charging stations, each with the charging power of up to 22 kW. The energy supplier/network operator warns the hotel management that it will have to pay significantly higher fees in future. Intelligently utilised load balancing means that this is not the case.

Without load balancing high costs originate with the charging of several electric cars

As a major consumer of electricity, the demand rate that Hotel Alpenstern pays does not depend on consumption. Instead, it depends on the peak load determined within one year. In our example, the peak load was previously 340 kW. On the evening that the hotel had the highest number of guests, the ten charging stations were all in use, increasing peak load to up to 560 kW, meaning that the demand rate per year increased by around €19,800 (demand rate of €903 * 220 kW of additional power).

The charging processes of electric cars are controlled through dynamic load balancing

Dynamic load balancing from The Mobility House means that the loading processes are intelligently distributed and shifted to periods in which there is load available for charging. This means that the previous peak load is not exceeded and the demand rate remains unchanged. The investment of around €4,000 (€400 per charging station) amortises in the first year alone and the high fees imposed by the energy supplier/network operator do not apply. The slightly longer charging process does not cause any inconvenience at all to the Hotel Alpenstern’s guests as they are staying overnight anyway.

The electric forklift truck manufacturer Birke would like to add 15 electric cars/plug-in hybrids to its vehicle stock for technical service employees. In order to charge the new fleet of electric cars, it procures 15 new charging stations with a charging power of up to 22 kW each. During checks on the electrical installation, it is found that the connection capacity for the building is insufficient and needs to be increased at great expense. Intelligently utilised load balancing means that this is not the case.

Without load balancing high costs originate with the charging of several electric cars

All 15 charging stations are installed and commissioned properly by a qualified electrical engineer. The connection capacity has been very low in the last year due to constant growth, but to date has been sufficient for normal operations. Now, Birke is considering increasing the connection capacity by approximately 330 kW. The company is expecting to pay around €25,000 for network connection costs and the construction cost subsidy.

The charging processes of electric cars are controlled through dynamic load balancing

Thanks to dynamic load balancing from The Mobility House, this expensive investment in infrastructure is not necessary. The fact that the charging stations are constantly balanced to the building’s current load ensures that the additional charging processes do not cause the available connection capacity to be exceeded. Fleet operation is not restricted by slower charging processes as the electric cars only reach the company site in the afternoon and can be conveniently charged overnight. As a result, it’s an easy decision for the company to invest €6,000 for costs (€400 per charging station) for load balancing.
