The future of E-Mobility: A Conversation with ChargeX

How a Bavarian startup may force you to rethink the concept of urban charging

13. March 2019 München

Germany has set itself the goal of becoming the lead market and provider for electric mobility by 2020 as part of its long-term zero emission mobility vision. Drive electrification reduces dependence on oil, slashes CO2 emissions and allows the vehicles of tomorrow to be fully integrated into new multimodal traffic system models.

The charging infrastructure is an essential part for the expansion of electric mobility. However, the charging infrastructure is expensive to install and is still in the developing process. Meet ChargeX – a Bavarian startup on a mission to improve existing charging infrastructure and reduce installation costs.

ChargeX has designed a modular system that allows users to charge multiple electric vehicles at one single charging station. The first idea for system came up while the founders Tobias Wagner and Michael Masnitza were observing a garage of their previous employer. “We had five charging stations for five electric cars, all arriving in the morning and plugging into their individual charger,” Michael explains. “Then, after about an hour, all cars where fully charged. The five charging stations and all grid infrastructure installed was therefore not used for the rest of the day. We thought that we can make a way more efficient charging system by distributing the charging from one charger over the day and save costs by doing so.”

The modular charging solution for electric cars by ChargeX can electrify multiple parking lots cost-effectively and with little installation effort. The modular concept gives operators of fleet parking lots and underground garages a flexible and futureproof solution to develop charging infrastructure.

With ChargeX hardware based sequential load management system, the hardware costs can be reduced by 50% compared to the cheapest competitor. The plug & play connector system can ChargeX charging station to up to seven additional sockets. Because of modular nature of the charge points, additional sockets do not require an upgrade of grid connection and allow an easy and flexible scale-up.

The intelligent system uses an integrated load management feature that switches between cars to ensure that the connected load remains consistent at all times. An intelligent charging algorithm then decides when the electric car to be charged based on the user’s mobility behavior.

ChargeX charging system is certified and can be installed like any other charging station. The next goal for the team is to ramp up their production in order to deliver more chargers faster and gain a foothold in the market. Their charging system is currently being tested at the E.ON test lab. Once the tests are successfully completed, both ChargeX team and E.ON intend to set up the first pilots together. “By setting up new pilot projects, we are able to improve the user experience with direct feedback from the user and refine our algorithm with the charging data we collect during the projects,” Michael says. “Aside from that, we continue growing our team and looking for investors for our series A financing round.”
