  3. CHARGING STATION: PLACE We need to find a place in our High School without the possibility of thefts, considering the weather, the long discharges and the easiness to park. 3/12

  4. CHARGING STATION: PLACE • Limit the place • Set a bike rack and anti-theft system. 4/12

  5. CHARGING STATION: PLACE • The place is very dark and it is illuminated permanently by artificial light. We want to improve the illumination conditions by photovoltaic panels. 5/12

  6. CHARGING STATION: PLACE • Students from 1ºESO (12-13 years old) made the wall lamps in Technology class. 6/12

  7. CHARGING STATION: PLACE • On of the requirements was: wires and circuits mustn´t be seen. 7/12

  8. CHARGING STATION: PLACE • Examples of other solutions. 8/12

  9. CHARGING STATION: SPACE • Students of 4ºESO (15-16 years old) made the electronical controllers. These controllers change the tension from 12-20V DC in the solar panels to 12V DC in the wall lamps. • We don´t need batteries since it´s a direct load, we take electricity directly from the Sun. • Students made also a solar • switch which cut the conventional • electricity. 9/12

  10. CHARGING STATION: LIMITATIONS • The battery load current must not be over 10% of maximum I and it depends on the capacity of the battery. • The type of batteries (Pb, NiCd, ions Li…) have different individual cell voltage. • Commercial battery chargers do special “tasks” in the battery cells, such as equalizing and getting rid of sulphates. • We design the charging station as a place which avoids the long discharges and which complementates the charging station the user has at home. 10/12

  11. CHARGING STATION ~/= NiCd __ ¯ NiCd ~/= Li, I1 __ ¯ Li, I1 ~/= Li, I2 __ ¯ Li, I2 CHARGING STATION: LIMITATIONS • An universal charging station means having as many different types of chargers as the different types of batteries we use. • The price of chargers is not expensive. 11/12

  12. CHARGING STATION ~/= NiCd =/~ Inverter __ ¯ NiCd CONTROLLER ~/= Li, I1 __ ¯ Li, I1 __ ¯ ACCUMULATOR ~/= Li, I2 __ ¯ Li, I2 SELF-SUFFICIENT CHARGING STATION • There is an energetic loss in the electrical conversion DC/AC/DC we must be aware of when the universal charging station. • The photovoltaic generating system complementates with an inverter.
