Tune adds 20% more battery on 2014 Volts, thank the French

In any event they claim to be able to modify 2014/15 volts to have 20% more battery capacity
And 130kw peak power as well

Any Canadian here willing to blow $500 Cad and do a Kilowatt meter before and after the enhancement?
And hopefully describe what they did as well.

I'm hoping these guys team up with the Volterado guys to make a reversible all in one tune

Ideas?

 

[jayoldschool]

Ok, so... how do they do it? We all know that GM has built in extra capacity that we can't use, so how do these guys access it?

 

[rmay635703]

A caveman would make an intercept device

A software elite would access the EV canbus and reprogram the modules
My guess is they are somewhere in the middle

Not clear what the web site means by "module"...however one way or the other it's a virtual certainty that it's really a bit of re-programming.

Doubtful they're adding battery capacity. Just playing with the operational parameters. There goes your Voltec warranty and conservatively treated battery life, even if it does work. Is it worth it?

Beware of this snake oil, sounds similar to all the other energy and mpg devices that have been proven to do nothing more than take your money.

This is how you tune any modern car - find and reverse engineer the engine operation parameter table. GM is especially conservative to reduce warranty costs so there's usually about a reasonably safe 20% increase in various operating parameters. In the case of the Volt I would look at the ICE engine's HP output, overall torque to the drive train, and battery reserve capacity.

The description seems to suggest a ~20% increase in the size of the usable power window, not an increase in the size of the battery capacity, i.e., the 2014 might get ~12.3 kWh usable instead of 10.3 kWh for a full depletion, the 2015 ~13.1 instead of 10.7. To quote the English translation of the article:

"The number of kilometers of autonomy will be increased by about 20%.
So, if you are used to 75 km in summer, you will add 15 km for a total of 90 km."

So, for $500 and a chance you will void your warranty if something goes wrong with the system while the module is installed, you may get an additional 15 km of range... and you may choose to have the module removed for $75... and reinstalled for another $75...

The section on recharge time and regeneration seems to suggest this is accomplished by getting your battery to overcharge itself, filling the overflow buffer at the top and eliminating the ability to do any regenerative braking until that battery power has been used. To quote the article:

"RECHARGE TIME AND REGENERATION

Charging (240V) will take about 45 more minutes (for approximately 2kWh more).
When the battery is full, there is no regenerative braking on the first kilometers traveled."

 

[frith01]

This sounds like the perfect thing to do AFTER the 100k battery warranty expires.

 

[viking79]

EREVs use less max charge in the battery to prevent damage to the battery while the generator is running. I wouldn't reduce that significantly.

 

[lexcyn]

I'd be all over this if 2013 was compatible... but it's not

 

[GTPprix]

We can do that here in the states and have for some time for a few friends. If people are really interested I'll revisit this conversation with our liability insurance carrier (had some issues with us when we were doing OEM hold mode retrofits on 2012's).

 

[Barry]

Personally, I like the fact that my battery health will be preserved for many, many years, and I would not want a mod that changes that.

I m interested!could be done with the aux can port?

 

[Coppersnowboarder]

Sometimes, you need to look a gift horse in the mouth. Drawing-down the full charge of the battery pack does not sound like prudent practice. I let my Hotronics footbed heater battery packs drain from one winter season to the next and the system failed, could not be brought back to life with a re-charge. Volt battery pack may have similar limits.

What kind of issues did you have with hold on 2012's? I'd still drive to Motor City for that update.

None, our insurance carrier didn't like us modifying propulsion systems on electric vehicles for some reason. Not sure if that's changed or not.

Chris, I just tried to PM you, but your mailbox is full.

To prevent breaking the "warranty", you could use a safer method...The driver and passenger WEIGHT loss method, 4 people at 200 pounds , or 4 individual at 175 pounds...over 100 pounds weight improvement, more then the tires, more the a full gas tank, 1/4 of the battery weight !!!..In short , good for your health, good for EV range, and no warranty issues...LOL
