What I forgot to mention is that I make my own biodiesel from waste vegetable
oil.
Still, diesel has the highest energy density of common liquid fuels, and can be
burned very cleanly, especially in external com
Regen can provide a substantial amount of energy back into the battery pack.
On my Volt, the dashboard displays the kW for both discharge and regen
charging.Regen can reach about 60 kW. The Volt battery is about 360
volts, so the regen current would be around 167 amps.

Hello, I am trying to find the settings for a 2008 Aixam Mega City with a
Curtis 1244 sepex controller. Some of the regen settings seem to be wrong. I
can provide a list of these settings I am looking for if it would be easier.
Thanks in advance for any help.

My statement that it seems the Tesla S may get up to around 70% back was
based on the data from the Drag Times article. The mass of the S is around
2150 kg, so calculate its kinetic energy at 114 mph, or about 51 m/sec, and
take the ratio of the regen energy they reported, 0.6kWh, to that expresse

Paul,
It looks like the confusion is about... two different things.
On the average, over a whole trip, all the braking that you do
might return 5 or 10% of your total energy invested in the trip, so
regenerative braking can extend your range by that percentage on average
over a whole trip.
The ~5

There are multiple benefits to regen that are not obvious: Battery
discharge voltage is higher and battery is thus more efficient after a

Hello all,
I own a 2012 iMiev in Montreal Quebec.
For reference the car has a 16 KWH battery and a 5KW heater.
The first winter I owned it I was on L1 charging only and it was a chilly
winter in the car. I had to use the heat sparingly because of the long recharge
times.
The second winter I

I've measured 50 - 55% of the vehicle kinetic energy back into the pack
during braking with only regen a number of times. The Tesla S seems to do a
bit better, with up to 70% back - the more aggressively you use it the more
you get back, but its not a huge effect. Dropping down from a summit I

Amen. Mount it in the EV so you can flip it around.

Nit picking here. But 50% is not quite "mostly".
And "recovered" is one thing, but storing it chemically in
