[Oeva-list] Liv wise Yaris 211 mile range.

[Ray Blackburn]

Hi all,

Here is an article on the Yaris and the company that built my EV.

EV Innovations’ research and development engineers critically analyzed all factors that affect the total mileage of the electric vehicle powered by lithium ion polymer batteries.
Using 29.6 kWh of lithium ion battery energy and the same urban and highway route, the cutting edge research team of EV Innovation closely working with Superlattice Power Inc., USA, achieved an increase in mileage from 120 miles to 211 miles. The cell voltage range was from 4.2V to 3.3V and driving tests are performed on roads and highways with real traffic situations using experienced drivers.
The development work emphasized on electrical regenerative power, modification of charging algorithm and cell voltage balancing using new version of battery management system.
 
My battery pack is 35 kWh so they would be running it down to over 90% to get 29.4 kWh out of it.  Perhaps they can put another 10 kWh in and then it would run down to less than 80% and go 170 - 200 miles.  The cell voltage range on my car charges to 4.09 not 4.2.  At a 100 - 110 mile range my car is very useful.  Still it would be more useful at 170 mile range.  50 mile range would not allow me to put over 6,500 miles on it as I have done since the middle of January.  Since my car is being shipped back to repair a gear box leak I will ask them about this.  Ray.
