Charge from battery to battery

The features of the battery described in the Ogron patent makes at fast charging a economic transfer from battery to battery possible.

How looks a 840 kW grid connection like?

This was until now the killing question for fast charging an electric car with big batteries. When somebody tells to charge 70 kWh batteries in 5 minutes, does he mean obvious a 840 kW grid connection?

Solar duty and the buffer battery

No! At a serious extension of solar electric power, day/night balancing by batteries will be urgent necessary. Out of this reason, my planned plus-energy house has an 50 kWh battery for 16,5 kW peak photovoltaic.

Buffer battery supplies fast charger in the garage

This buffer battery for the solar electric power can be also used to supply a fast charger. Not with 840 kW, because a 50 kWh battery can not charge full a 70 kWh battery, but maybe with 100 kW. A 100 kW charger would mean at a medium sized car 666 km/h charge speed. Really enough for domestic use, when coming home nearly empty and it's necessary to drive soon to an other location. Alon would be a 100 kW charger in the garage a total luxus, the requirements of a power supply based on sun and wind makes the buffer battery necessary in the house. Let's see how much will be 2030 a 100 kW fast charger. I have seen the first notebooks 1988 for $10,000. 20 years later is a OLPC (One Laptop per Child) far better than the first notebooks, but costs only $100, a single percent from the old price.
