With a new battery! What mileage can it achieve on a single

Lots of people here rabbiting on with zero knowledge. My car
is 2012, any battery deterioration is undetectable.

Well well Harry, perhaps you've e found a way to reverse
chemical ageing you might get a Nobel prize for that!!....

Well ****-fer-brains, you don't suppose electric cars are not
fitted with range remaining and battery charge condition
instruments? If so you must be really brain dead.

All I have to go on is the instruments fitted to the car. The
battery "fullness" indicator hasn't changed much on the regular
journeys I make. The "pips" disappear at the same places on a
journey that they always have.

I always charge the battery at optimum time/conditions.

You might find it informative to see if there is a smart phone app
for talking directly to the car's diagnostics. My friend with the
Leaf found that there is a world of difference between what the in
car displays tell him, and what the sensors are actually recording
before "processing" by the car.


T The cars instrumentation displays as much as it measures. So
interpretation of the sensors won't tell you anything more.

On the leaf they clearly don't... For example, the real time readout
from the diagnostics show that the in care display speed is both
averaged, and also scaled so as to over-read. The unprocessed speed is
accurate when measured against a GPS, and shows far more small variations.

The physical condition of any battery can only be determined by
completely charging and discharging the battery and measuring
voltages and currents.

Again the diagnostic readout will allow you to read a battery health
figured based on recent full discharge results. It provides for more
detail than the much cruder limited number of "steps" shown by the car.
FWIW, on my mate's car it has dropped from around 92% capacity when he
got it, to about 87% now.

I don't know the operational principle of the panel instrumentation,
ie instantaneous charge/discharge current, power remaining in the
battery and range remaining. It seems to be unconventional.

The instantaneous power is not calibrated and I don't know if it's
linear or not. But gives a good indication of what's happening and
(un)economic driving.

The range remaining computer is useless.

The power remaining in the battery seems to be spot on AFAICT.
