Power Sonic and the E-C02Tainer: A Mobile Charging Station for Electric Cars

Electric driving is sustainable. But generating your own green electricity on location is even more sustainable. That is the idea behind the new e-CO2tainer from Mobilis. The first copy of this green mini-power plant was commissioned in mid-November.

Solar panels, wind turbines and biofuel installation

The e-CO2tainer (pronounced: Ecotainer) is a mobile unit where drivers can charge their electric cars at project locations. The required electricity is generated with solar panels and wind turbines placed on the unit and a generator placed in the unit that works exclusively on biofuel (not on biodiesel). An off-grid solution in technical terms.

The e-CO2tainer is a private development of TBI company Mobilis, done in close collaboration with Power Sonic EMEA from Nijkerk, specialized in energy storage via battery systems.

Significantly reduce CO2 footprint

Jeroen Ritzer-van Dinther, sustainability coordinator at Mobilis: “In order to significantly reduce our CO2 footprint, we want Mobilis to have an almost entirely electric fleet by 2025 at the latest. That transition started in 2018. My management asked me to investigate how we can also involve our project locations. A suitable grid connection is not arranged there from day 1, sometimes not even possible at all. Or it is far too expensive to install a fixed loading facility for a limited period. ”

Mobile, fast and not fossil

Jeroen Ritzer-van Dinther consulted various market parties with these important conditions. He was often told “yes,” “but,” or “we can’t.” Except for the energy storage specialists from Power Sonic EMEA, which took up the challenge enthusiastically. René Assies, managing director of the Nijkerk company: “As a supplier of batteries, we think along with us about smart applications and customized solutions. We have a lot of experience with storage applications for, for example, the telecom sector and data centers. The Mobilis initiative appealed to us. Together we have further developed the idea. ”

Power Sonic EMEA is an American company that also has branches in Mexico, Great Britain, France, Israel and the Netherlands. The first e-CO2tainer was built at a production site of the company in England. The unit was delivered in mid-October on the site of Voorbij Funderingstechniek in the Port of Amsterdam, which, just like Mobilis, is also part of TBI Infra.

Six electric cars at the same time

Six cars can charge at the same time per mobile container. The e-CO2 container stores the self-generated power in redundant batteries; If one battery has to be charged, the other battery will take over the delivery. René Assies: “We have implemented the unit for the future. Lead batteries have now been chosen because lead is the most recycled metal in the world. But once the nickel-zinc battery, the most durable, is suitable for this application, we can start using it immediately. The generator is also already prepared for hydrogen.”

Also electricity for site office

The now-developed e-CO2 container is a 1.0 version, emphasizes Jeroen Ritzer-van Dinther. “We now focus primarily on charging electric cars. But the principle is so simple that the e-CO2 container can also be connected to a building site to supply electricity there. There are already 32 Amp. 3 phase connections on the e-CO2 container. A mains connection of 3×125 amp. may then be lowered to 3×80 amp. or even 3×60 amp. This immediately results in a cost reduction. An on-grid solution in technical terms.”

As mentioned, a connection to the electricity grid is also possible. Then power is supplied to the grid connection if it has a peak demand and power can be supplied to the unit if the demand on the grid is lower. The e-CO2tainer can thus, for example, serve as a permanent unit for tunnel installations and generate income.

Only organic residual products from the immediate vicinity

The solar panels and the wind turbines are the primary energy sources. The biofuel installation acts as a backup in the event of insufficient capacity. Jeroen: “We only use organic residual products, preferably products from the immediate vicinity of our project locations.” In the near future, the sustainability coordinator for Mobilis will provide applications where electricity is also extracted from the e-CO2tainer from, for example, pile driving. Furthermore, a smaller version of e-CO2tainer is possible. These can then be placed modularly and in series, depending on the demand of the customer.
