CLEMAP - Swiss intelligence for charging with solar power without unnecessary grid expansion

To achieve the net-zero climate target by 2050, we need more electricity. For charging electric vehicles, for example. This electricity can be produced with photovoltaic systems on the building. However, this rapidly increases the feed-in and feed-out of a property, meaning that the connection to the electricity grid has to be expanded at great expense. To avoid this, what is needed above all is more intelligence in the building. The innovative load management system developed by CLEMAP AG in close cooperation with Otto Fischer AG does just that. The algorithms of the CLEMAP technology coordinate the charging of charging stations from different manufacturers around the building, prioritizing or dynamically limiting the charging power depending on the electricity production of the photovoltaic system on the roof. The load management system can even adjust the charging current so that charging is carried out exclusively with solar power. The solution is 100% "Swiss Made", developed in Zurich and produced in Ticino.

The CLEMAP solution consists of a compact measuring device including a local control function, which is installed in the building's distribution board or fuse box. The inconspicuous device contains a concentrated load of intelligent algorithms and interfaces for power monitoring: the energy flows in the building are analyzed and the loads are optimized on this basis. Additional measurements are not required. Software enables remote control of the charging stations, monitoring via a dashboard and, if required, billing.

CLEMAP AG was founded six years ago by five engineers from ETH and SUPSI, including the current CEO Gino Agbomemewa and COO Pascal Kienast, who have known each other since their childhood days in Ticino. "The demand for energy monitoring systems for buildings was growing rapidly at the time. That's where we started, with the aim of developing networked modular energy platforms for monitoring and optimizing energy flows," says Gino Agbomemewa, looking back. The founders quickly realized that there were still few practical, manufacturer-independent load management solutions, especially for electromobility. The challenge: manufacturers of charging stations and photovoltaic systems have their own, non-standardized interfaces. Otto Fischer AG was one of the first customers and sales partners of CLEMAP AG. It needed load management solutions for its customers. A photovoltaic system with 257 kWp is installed on the company building of Otto Fischer AG. This system was integrated into the system. "Our powerful device controls over 30 AC and DC charging stations from different manufacturers. It can be easily put into operation by electricians without pre-configuration, has low investment costs and is scalable from two to fifty charging stations," explains Pascal Kienast. Otto Fischer AG is very satisfied. "Thanks to the solution from CLEMAP , we can take all user groups at Otto Fischer AG into account: The freight forwarder with the electric van, the employees with their private vehicles and the visitors. And we were able to significantly increase the self-consumption of our photovoltaic system," says Alessandro Buriola, Head of Product Range Development at Otto Fischer AG.

Today, 10 people work at CLEMAP AG in Zurich. It is well established on the market and is already active in other countries. It is constantly developing its solutions and expertise in various customer and research projects. The CLEMAP energy management solutions help to contain the costs of grid expansion. For example, the CLEMAP device is already ready for grid-supporting measures such as flexible tariffs or vehicle-to-grid. "Charging stations always want to charge as quickly as possible and are usually stupid. Thanks to CLEMAP , they become a key element of a cost-efficient energy transition," adds Gino Agbomemewa.
