300 km of autonomy corresponds to a battery of 60 kWh in mixed use (excluding motorways), i.e. less than 20 kWh / 100km. On the motorway, consumption commonly reaches 30kWh / 100km Currently, the kWh of battery has fallen below 200 € or $ 200, therefore a gross value of $ 12.000 for 60kWh In 2009, ...

"Since 2015, all batteries are guaranteed for 8 years unlimited mileage." It's already better than Kia, and I'm not talking about BMW, PSA, Renault etc ... which are satisfied with the legal warranty of 2 years (except special conditions ...) All this makes you want to look on the You're here...

You have to consider the entire system and its long-term reliability. To supply 250kW for 1 minute, you need a minimum of a 25kWh battery pack providing 10C for one minute PLUS a 250kW inverter. We can consider a smaller pack by increasing the number of Cs by taking ...

I belatedly the technical proposal of Dirk pitt. 8) Economically, it is unstoppable. Technically it is quite defensible. The wear of the motor brushes in intensive use is the only weak point of this technical choice with a lower efficiency. All of this is largely ...
