Increase selfconsumption through smart charging

AI Quick Summary

As electric mobility and renewable energy system find more and more adoption, often technical interfaces are hindering a smart communication and control. Through an Energy Management System that monitors PV-System, the building energy consumption and controls the charging infrastructure, CLEMAP plans to increase by high percentages the selfconsumption degree of commercial building infrastructure and improving the economic viability of EV- and PV-systems. With a strong adoption of Electric Vehicle and PV-System, a rather low feed-in tarif of PV produced electricity and high electricity prices, commercial building owners are gaining in interest to increase their selfconsumption possibilities and lower expenditures. Nevertheless, they are challenged with the technical infrastructure, on one side, Smart Meter are not designed to function as Energy Management System, on the other side EV-Charging Stations and PV-System have different connectivity system not permitting a seamless integration. Commercial adoption is hindered through technical complexity and costs. Modern charging stations can becontrolled dynamically and allow to set multiple charging power levels. A typical PV-System can not be controlled and as the sun shines the energy should be used as much as possible within the existing building. Thanks to an Energy Management System based on the CLEMAP Load Management the charging infrastructure can be controlled according to the electricity use in the building and to the available renewable energy. This will allow to increase the level of selfconsumption and improve the economical payback time of the EV andPV-System.The project is planned to be implemented in collaboration with Otto Fischer in an existing commercial building in Switzerland, where EV- and PV-System are currently installed. First data provide indication that the selfconsumption of a commercial building can be improved by 10-30% depending on the configuration. Within the considered case where a PV-System of 257kWp is installed we expect an improvement of selfconsumption by 30’000kWh per year, therefore a CO2 saving of 4.5tonnes per year (considering that electricity is not needed from the grid and saving 0.15 kgCO2eq/kWh).Thanks to the high compatibility of the system, the proposed solution can then be scaled to the commercial building in Switzerland and Europe. Through the network of Otto Fischer we can access thousands of commercial buildings in Switzerland. Over similar electric distributor channels a further expansion can be driven in Europe.Within the project following people will be involved: Dominic Steiner as lead engineer from CLEMAP and Melanie Fischlin as Marketing Manager. Dominic will improve the existing CLEMAP Load Management System and Melanie will be responsible to generate the necessary document for scaling the solution on our platforms. Further project participants are willing to join to support the implementation.

Project Idea Description

With a strong adoption of Electric Vehicle and PV-System, a rather low feed-in tarif of PV produced electricity and high electricity prices, commercial building owners are gaining in interest to increase their selfconsumption possibilities and lower expenditures. Nevertheless, they are challenged with the technical infrastructure, on one side, Smart Meter are not designed to function as Energy Management System, on the other side EV-Charging Stations and PV-System have different connectivity system not permitting a seamless integration. Commercial adoption is hindered through technical complexity and costs.

Modern charging stations can be

controlled dynamically and allow to set multiple charging power levels. A typical PV-System can not be controlled and as the sun shines the energy should be used as much as possible within the existing building. Thanks to an Energy Management System based on the CLEMAP Load Management the charging infrastructure can be controlled according to the electricity use in the building and to the available renewable energy. This will allow to increase the level of selfconsumption and improve the economical payback time of the EV and

PV-System.
