iDNES explored our mobile hydrogen electric car charger H2BOT

The Czech company DEVINN has introduced a mobile charger for electric vehicles. A remotely operated vehicle will drive up to a discharged battery car and refill it with energy produced on site from hydrogen.

The mobile hydrogen gas power generator produces electricity and heat energy. The mobile hydrogen power generator was introduced by the Jablonec company in 2020, a year later it powered a stage at the Rock for People music festival and helped a school and two houses in tornado-hit Moravia.

Now the company from Jablonec nad Nisou has come up with another novelty - a remotely controlled charging station for electric vehicles H2BOT using hydrogen. DEVINN will present the device tomorrow (Wednesday 19 October 2022) at the Hydrogen Technology Expo in Bremen. It will also be seen a week later at European Hydrogen Week in Brussels.

The remote-controlled vehicle takes up a third of the parking space and includes an integrated fast charger. The H2BOT generates electricity for charging on site using a hydrogen fuel cell. It combines hydrogen from a pressurized storage tank with oxygen, which the device obtains by drawing in ambient air. This generates electrical and thermal energy. The only emissions from the process are water vapour and water.

So the electric car driver does not have to go to the charger. "On the contrary, he comes to it. The user orders the charging via the CAREN mobile app, which sends instructions to an operator who remotely guides the vehicle to the charging point. Thanks to the installed cameras, the driver has a 360° overview of the situation around the vehicle at all times, and the safety of the traffic is ensured by multiple security systems," says Luboš Hajský, head of DEVINN. 

"The H2BOT then automatically opens the charging socket using the robotic arm and connects the device to the electric car. The operator can be on the other side of the world at that moment, and the device works on site without any additional operator." 

H2BOTu has a DC/DC charger on board, i.e. fast DC charging. "The H2BOT can charge a 60kWh Skoda Enyaq in 45 minutes, charging five to seven cars per hydrogen tank," Schwarz explains.

"At the moment, we see parking lots at shopping centres and areas on the outskirts of big cities where it is not possible to fit all parking spaces with a charger as the ideal place to use our device." says Luboš Hajský. Thanks to their low noise level, H2BOTs could also cruise parking lots at night without any problems. 

"It should be noted that for the system to be truly green, the hydrogen that H2BOT consumes must also be of green origin. Hydrogen is suitable for storing energy from renewable sources and will play a significant role in the energy mix in the future," adds Luboš Hajský.
