Nissan and Endesa to Develop CHAdeMO Quick Charging Network in Spain

Nissan Motor Co., Ltd., and Endesa, Spain’s largest electricity supply company, are developing a Quick Charging network for electric vehicles.

Under a Memorandum of Understanding signed by both parties, Nissan and Endesa have agreed to advance the technical progress and deployment of Direct Current (DC) quick charging technology throughout Spain. This is in parallel to the work started earlier this year between Endesa’s parent company, Italy’s ENEL and Nissan’s Alliance partner Renault on Alternative Current (AC) quick charging technology.

The DC technology will be based on the CHAdeMo standard (earlier post) for electric vehicle charging stations. The network will be compatible with the Nissan LEAF electric vehicle, which is expected to go on sale in Spain in June 2011.

In addition, Endesa will invite Nissan to take part in the SmartCity Project in Malaga and its Quick Charging Demonstrator Project in Catalonia. For its part, Nissan will support the certification process ensuring that Nissan LEAF and Endesa’s Quick Charge device are compatible and the Japanese car maker will share energy supply knowledge and ideas learned during the development of the Nissan LEAF and other EV projects with Endesa.

Endesa has pledged to develop a sustainable transport policy based on the EV as a key element in combating climate change, a cornerstone of its Sustainability Strategic Plan 2008-2012.

The CHAdeMO—or Charge to Move—standard was originally determined and agreed by a coalition of Japanese companies including Nissan, Toyota, Mitsubishi and Fuji Heavy Industries working closely with the Tokyo Electric Power Company. Today the association includes representatives from more than 150 Japanese and foreign companies, as well as local governments. Endesa is a regular member of CHAdeMo. Together with Enel, they represent two of the three companies from the European power industry in the coalition.

EVs with Solar power make sense.

Banks of used EV lithium batteries could be used in solar charge stations for another 4/8 years. DC to DC charges are more efficient and quicker.

If quick charges are to be done during the day, a good grid will be required. They make no mention of a battery bank per charger, just AC or DC. Day usage is usually 2x night and 3x on summer days. If you don't want peak plants with natural gas turbines, then those big solar towers will have to get cooking.

Even with a battery bank, the charger would be out of commission when it is recharging, otherwise there is no point. So if a car gets 30kWh in ten minutes, the next person may have to wait an hour or more for the charging station to recharge. That is not a problem if you have more charge stations than customers, but there is obviously a point where that may not be the case.

The next person would just have to charge at grid rates; there is no sense in charging a battery just to discharge it into another battery when the second one is waiting the whole time.

More to the point, the extra battery would let the charger maintain the charging rate when grid conditions require the immediate demand to be cut back. This could go on until the stationary battery is depleted. Grid regulation services are another possibility.

We are talking about QUICK charging, without mention of any battery banks. We come back to the same scenario where 1000s of cars ALL want to quick charge off the grid. I will not try to decode your cryptic response.

Sorry if I'm presuming too much knowledge of e.g. AC Propulsion's white papers.

Until Harvey D introduced it in the first comment.

You presume too much knowledge all the time, nothing new here :)
