Answers to your questions about our technology

Yes. The SmartCable is compatible with charging infrastructure of other providers. Start the charging transaction with the respective provider’s access token and charge with the respective tariff. As an alternative, you can use the ubitricity eRoaming option to gain access to more than 60,000 charging spots across Europe.
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.
Nowadays, most vehicles are equipped with a vehicle-side locking mechanism. In this case, the cable is locked both into the vehicle and the socket during the charging process. Nobody can pull the cable out of the socket or from the car. You can end the charging process by unlocking the vehicle - then, the cable is unlocked both from the socket and the car as well. Before opting for a SmartCable, we would therefore encourage you to check whether your car offers this function. If your car should not offer a vehicle-side locking function or if it requires a Type-1 plug on the vehicle side, please refer to your car retailer in order to discuss the necessary measures for protecting the cable against theft. Should the cable be stolen out of the car or should you lose your SmartCable, please call our Support Team immediately - then, the cable needs to be deactivated to make sure no charging transactions are billed to your account. Once deactivated, the old SmartCable can no longer be used.
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 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. And in the future, this balance will shift even more 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.

At the charge point

That can happen if your SmartCable hasn’t connected with the mobile network for a while. Please bring your SmartCable to a location where it can establish a mobile connection and press the buttons „1“ und „Checkmark“ at the same time for six seconds. The SmartCable reboots and you can start to charge as usual immediately.
On the one hand, your car could already be completely charged. Also, some vehicle-sided settings might prevent your car from charging – so please check your vehicle settings for such obstacles. Generally, ubitricity technology is conform with all EVs licensed in the EU and nothing should keep your EV from charging in this respect.
Please use the form “Report a problem” of the respective SimpleSocket in the charge point search of the ubitricity app. The SimpleSocket will be repaired as soon as possible. In urgent cases, please contact support: +49 30 364 288 300.
Not to worry – that can happen sometimes. Plug your SmartCable into the SimpleSocket once more with more pressure and into the car on the other side – just like when you charge normally. Now, pay close attention to the SmartCable’s display and try to finish the charging transaction again as usual. Normally, the SmartCable should disconnect normally from the SimpleSocket now. If this should not be the case, please contact support: +49 30 364 288 300.
Not to worry – that can happen sometimes. In this case, please plug your SmartCable into the SimpleSocket and press the two buttons „1“ und „Checkmark“ at the same time for six seconds. Your SmartCable reboots and you can start to charge as usual directly afterwards.
Your SmartCable saves the charging data and transmits them automatically once a mobile connection is available. This way, you can also charge at locations without a mobile connection (such as underground car parks). However, your SmartCable does need to connect to the network at least once a week. That’s why it’s best to always keep your SmartCable with you in your car.
Yes. The SmartCable is compatible with charging infrastructure of other providers. Start the charging transaction with the respective provider’s access token and charge with the respective tariff. As an alternative, you can use the ubitricity eRoaming option to gain access to more than 60,000 charging spots across Europe.
If you want to finish the charging transaction, unlock the plug on the vehicle side by opening your car. Always pull the plug from the car first. As soon as the SimpleSocket’s LED is orange, the plug is unlocked at the charge point as well and can easily be pulled off. This finishes the charging transaction.
It’s quite simple: The SimpleSocket’s LED flashes blue if it’s ready for use. You can now plug your SmartCable in the SimpleSocket and your vehicle. The charging session starts automatically once your car is ready. When charging, both plugs are locked and the charge point’s LED pulsates green.
