Grelinette wrote:Some sentences that seem interesting to me on the management of EV batteries,
from of the link article given by Petrus where it is advised to load at only 70% -80%)
"It has been shown that the battery models currently fitted to Elon Musk's vehicles were starting to suffer from a 5% load capacity degradation after the first 80 km path".
"We have to wait 240 km more (i.e. 320 km per kilometer) so that the battery tires a little more and drops to only 90% of its original capacity"
"the trick already known to save your li-ion battery is to daily charge the battery up to 90% rather than 100% - a total to reserve for long journeys, and thatElon Musk for his part advised an ideal load of 80%
"Jeff Dahn goes even further, he indeed advises for his part to stop at 70% of the capacity, especially for the Model X SUV, which is fully electric. "
"Tesla car can travel 320 km on full charge. A distance that falls to 240 km if you follow the advice by Jeff Dahn "
"in Finland, a taxi driver has just reached the 400 km distance traveled, for a only 7% battery damage"
"Tesloop ...: we just saw one of the Model S exceed 480 km by mileage [color = # FF0000] in just two years[/ color] "
“Toyota has used this for a long time on hybrid cars: the battery charge is managed in such a way that it never drops below 30% or 40% and never goes above 70/80%. When the ODB indicates that the charge is full, in fact it is at 70/80%.
We note in passing that Toyota would implement a gauge system which gives "false" information on the battery charge level in order to preserve its capacity. It is not yet a "Smart gauge" but it comes close!
A "smart gauge" would be for me a gauge that adapts to the driver's habits and indicates the best time to recharge the battery and calculates the optimal charge, for the same car, depending on whether you are:
- a housewife who makes small daily trips to go shopping
- a craftsman who will ride all day to go to his work sites
- an employee who will make a very regular trip morning and evening to come and go from work
- a salesperson who will make a long journey every 2 days
- a tourist on a ride
- Etc. ..

On the highway, consumption commonly reaches 30kWh / 100km
Currently, the kWh of battery has fallen below 200 € or 200 $ so a gross value of 12.000 $ for 60kWh
In 2009, it was worth over $ 1000
So we will have to wait a little longer for a car with a range of 300 km at € 8.000.
