Answers to your questions about our technology

Users’ and data’s security are our top priorities when developing the systems. We’re using a so-called end-to-end security which employs an authenticated authorization using a PKI (Public Key Infrastructure) between the components. Additionally, communication is encrypted. Our security concept has been developed in cooperation with the Security Working Group of the National Metrology Institute of Germany.
The SmartCable contains technology for monitoring the whole charging transaction – starting with authorization and consumption metering and including the transfer of consumption data and billing process.
The SmartCable with integrated electricity meter reduces the charging spots to lean SimpleSockets. They are technically compact and nearly free of running costs, making ubiquitous intelligent charging infrastructure reality. Drivers take their mobile electricity contracts along with them to the charging spot and receive one bill for all charging transactions. Charging and billing data are shown live in the user portal – for the SmartCable as well as the SimpleSocket.
During the transaction, the technology is locked on both the vehicle and the infrastructural side. Nobody can pull the cable out of the charging spot or the car and it’s protected from robbery. Drivers can end charging transactions by simply unlocking the car.
The SmartCable is compatible with other charging infrastructure, but drivers then charge to the conditions of the respective provider, not their own tariffs.
Theoretically, EVs could be charged at normal sockets – but then, drivers can’t use separate (ecological) tariffs. For smart grid integration, it’s better to address the respective consumer (i.e. the EV) separately.  Also, everyone in the household would have to pay for the electricity used by the car because the electricity would be metered by the normal household meter, not the individual user’s meter.
Our SimpleSocket’s current maximum workload amounts to 4.6 kW (20 A 1ph). As we’re complementing conventional charging infrastructure by a “low power, low cost”-solution, this is what suits most of our use cases.
ubitricity takes all usual protection measures such as lockable plug connectors in order to prevent thievery or unauthorized charging interruptions as well as resilient hardware cases.
In this case, a subsequent data transaction enables charging by using an expiring certificate that actualizes itself when reconnecting online.
In order to charge EVs as flexibly as possible, two to three charging spots per EV are required. Conventional wall-boxes and charging stations contain metering and communication technology, resulting in high capital and running costs. In Mobile Metering, one single meter is integrated into the vehicle, which means there is only one meter per vehicle or SmartCable. This reduces the charging spot to a lean SimpleSocket – without expensive stationary technology and with next to no very low running costs. Ubiquitous smart charging infrastructure is made possible.

Answers to your questions about electric mobility

No, electric power is no free give away. But driving on electricity is much cheaper than driving on conventional fuels! A gas fired combustion engine consuming 7 l/100km Driving with electricity is already much cheaper than driving with conventional fuels. A normal gasoline car uses roughly 7l/100km and thus costs 9€ per 100km. In contrast, a normal EV runs this distance on 20 kWh, amounting to only 7€ for the same distance. In the future, driving with renewable energies will get even cheaper as they’re not limited – as opposed to crude oil or other fossil fuels. The growing demand for crude oil is facing ever scarcer resources and thus petrol prices will be rising on the long run. This does not affect EV drivers.costs you some 9€ for these 100 kilometers today. An electric car using 20kWh on the same distance only costs you some 3€. And in the future, this balance will further shift in favour of electric vehicles. Increasing global demand for crude oil and diminishing supplies will translate into higher gas prices in the long run. If you are driving an EV, this does not affect you.
As of now, no car, not even an EV, is totally CO2-neutral when taking into account its whole life-span. But renewable energies produce no emissions in the actual production process – which means that your EV drives practically free of emissions if you charge renewable energies. Also, driving EVs reduces greenhouse gas and particulates emissions. It’s crucial to charge renewable energies – otherwise, greenhouse gas emissions are not reduced but only shifted. Also, EVs emit next to no heat or noises, making them friendly to their direct environment and, overall, to the climate.
In the first step, EVs are actually nothing more than another consumer that needs to be connected to the grid in order to be of use. But making use of smart grid integration and ubiquitous charging infrastructure, EVs could be much more than that. Their batteries become a distributed saving network, balancing energy shortages by giving a little of their charged electricity back into the grid or absorbing overproduction. Those grid services are summed up under the term “Vehicle to Grid”.
Germany’s Federal Government is looking to put one million EVs on German roads by 2020. The German power grid would already be able to handle this number of vehicles – no need to worry about charging EVs causing a blackout in the near future. As the number of EVs is rising slowly, grid operators have sufficient time to enhance the grid’s capacities as required.
