The energy produced by braking the Madrid Metro trains can be used to recharge electric car charging stations on surface, by means of the baptized as 'Metrolineras'.
The first of these charging points has been placed next to the metro station Sainz de Baranda, in the Citroën facilities in the capital.
A "Metrolinera" in Madrid
The project, called Train2Car, is developed by Metro de Madrid, Universidad Pontificia de Comillas, the company Computer Systems and Automatic General System (SICA) and the Centre for Energy, Environment and Technology (CIEMAT), under the Ministry of Economy.
Metro systems are normally designed to take longer and manage the most efficient way possible electricity flowing through its facilities, including trains generated during braking, is stored for later use.
Now, the project Train2Car aims allocate part of the 'excess' energy to recharge electric cars.
To maximize the efficiency of the system, Train2Car must consider and manage all the features of the built components from the supply needs for the metro as the train traffic and the times for loading demand for electric cars.
To this end Train2Car project currently is under development, during which it is possible to use the 'Metrolinera' for free 20-minute loads.
Available for electric car charging energy is not obtained directly from the metro, but proceeds from the batteries currently, that are used to store energy generated during braking trains to return later as a traction energy, when the vehicle starts to move.
For Train2Car project has been necessary to specifically modify these batteries manufactured by the multinational Siemens.
The charging post for electric cars installed by Siemens is manufactured by GH Group company based in Valencia. The Post delivers 50 kW of power and uses the protocol load quickly and safely CHAdeMO, compatible with most electric cars on the market.
The project seems to be interesting, although I think it is still soon, to get used to the electric car.
Till soon, kind regards,
Luis.
