Charging of electrical vehicles

Energy storage interacting with chargers for electrical vehicles

Massive rollout of EV chargers have an impact on both the maximum incoming power capacity and the electricity bill. Introducing energy storage and smart interaction with the chargers, can limit this.

Modular and scalable energy storage solutions to meet any requirement

Minimize your electricity bill and maximize the return on PV investment while helping DSO's.

When a number of chargers for electrical vehicles are installed in parking lots/garages or office buildings, there are often challenges.

The increased peak power will often exceed what the grid connection to the building or location was designed for. In order to address this the feed to the building may have to be upgraded. In the simplest case, by changing the rating on the incoming fuse, but more commonly the incoming cabling or even upstream transformers have to be upgraded. This has a significant cost for the DSO, which they have to pass on to the consumers.

This maximum peak power will also have an impact on the demand charge for the building. This is a monthly charge which is based upon the highest average power over a short time period (typically 15-30 minutes). The demand charge can have a significant impact on the electricity bill.

In addition, charging of electrical vehicles have a tendency to happen at the time of day where the grid is heavily loaded, and the electricity price is high.

An energy storage system, communicating and interacting with the EV chargers in a smart way, can address all off the above issues.

With the ability to keep the peak power down, the grid investment may be avoided and the impact of demand charges will be limited.

The energy storage system will also make it possible to buy the power when it is cheap, during low peak hours, and use it in the evening when everyone returns from work.

Finally the energy storage provides an excellent way to also utilize any excess solar energy. Rather than selling this back to the grid for a low price (or no payment at all), it can be saved and utilized when the price is peaking.

Case studies

Research and development is at the core of our business idea – together with our clients we are deploying solutions that reduce power cost without reducing power consumption.

Distribution grids

Energy storage for power quality support and decongestion of distribution networks

Distributed energy storage solutions can help DSO's in meeting challenges due to increasing power peak demands and intermittent power production.


Using energy storage to generate revenue on lazy assets in telecom networks

Telecom networks possess a significant energy storage capacity. This can be utilized for "ancillary services" without having any impact on the reliability for the telecom network.
