Flex­i­ble overnight: sup­ply­ing elec­tric vehi­cles with ener­gy at home with­out grid overloading

In the research trans­fer project ismartC, sci­en­tists at BTU Cot­tbus-Sen­ften­berg are work­ing on an inte­grat­ed charg­ing man­age­ment sys­tem that enables the intel­li­gent inte­gra­tion of charg­ing process­es into the pow­er grids.

The planned phase-out of nuclear pow­er in 2022 and of coal-fired pow­er gen­er­a­tion in the 2030s, as well as the fur­ther expan­sion of renew­able ener­gies, jeop­ar­dise the secu­ri­ty of sup­ply of the elec­tric­i­ty sys­tem. “Due to the enor­mous increase in elec­tric vehi­cles and charg­ing points, the chal­lenges in pow­er grid man­age­ment are inten­si­fy­ing,” says Mark Kuprat, research asso­ciate, Depart­ment of Ener­gy Dis­tri­b­u­tion and High Volt­age Tech­nol­o­gy. “Oper­at­ing costs and grid man­age­ment require­ments are increas­ing. Com­pa­nies are increas­ing­ly ask­ing us for local load man­age­ment to pre­vent over­load­ing of elec­tri­cal equipment.”

The goal of the researchers in the trans­fer project ismartC is an indi­vid­u­al­ized charg­ing man­age­ment sys­tem that inte­grates pri­vate house­holds. “Peo­ple come home from work and load their vehi­cles after work at about the same time. The result is that the pow­er grids are over­loaded,” says Saman Aman­pour, co-founder in the project. “Our process allows us to adjust load­ing times so that they can be auto­mat­ed to, for exam­ple, evening, night or ear­ly morning.”

The Inte­grat­ed Smart Charg­ing (ISC) sys­tem pro­vides the flex­i­bil­i­ty need­ed for secure oper­a­tion of pow­er grids, reduc­ing pow­er pur­chase costs by up to 50 per­cent with­out lim­it­ing the mobil­i­ty needs of elec­tric vehi­cle users. The sci­en­tists Mark Kuprat, Saman Aman­pour, Mikhail Ashkerov and Bas­t­ian Gar­nitz are devel­op­ing a pow­er­ful IT infra­struc­ture, a data­base man­age­ment sys­tem, a smart­phone appli­ca­tion and the asso­ci­at­ed inter­faces and serv­er environments.

The project ismartC is fund­ed by the Fed­er­al Min­istry for Eco­nom­ic Affairs and Ener­gy (BMWi) with­in the EXIST Research Trans­fer (EFT) with 700,000 Euros. The project is locat­ed at the BTU Depart­ment of Ener­gy Dis­tri­b­u­tion and High Volt­age Tech­nol­o­gy for the dura­tion from July 1, 2021 to Decem­ber 31, 2022 and is super­vised by the Project Man­age­ment Organ­i­sa­tion Jülich (PTJ).

The com­pa­ny ePHANT, which is cur­rent­ly in the process of being found­ed, is a spin-off of the BTU Cot­tbus-Sen­ften­berg, which will trans­fer the many years of research work in the field of grid-serv­ing and elec­tric­i­ty mar­ket-based inte­gra­tion of the charg­ing process­es of elec­tric vehi­cles into a com­mer­cial prod­uct. The spin-off emerged from the EXIST research trans­fer project Inte­grat­ed Smart Charg­ing (ISC). Founders Mark Kuprat, Saman Aman­pour, Mikhail Ashkerov and Bas­t­ian Gar­nitz plan to launch ePHANT Mobil­i­ty Solu­tions in ear­ly 2023.
