There is a price to be paid by not charging the S-10EV to full, and outweighs the benefit of not charging to full. I'll explain. Each of the 26 NiMH battery modules exhibit a slightly different impedance and parasitic discharge rate. Differing module temperatures occur due to...

I am thinking about selling my S10E and would like to get the list's input on what price it should sell for. This is a 1997 S10E with the EVBones NiMH upgrade. I got the truck in March 2006 with 12600 miles on the truck with the recently installed NiMH pack. The truck now has...

I don't have the data to back up my opinion, but I think full 100% charging does shorten battery life. On the Toyota Prius, the NMH batteries are cycled between 40% and I think 85% SOC. They could get the most life out of their batteries in this range. This makes sense to me....

Well said about the regen. Regening up to a stop light is *never* more efficient than if you had just been patient and timed your driving right to wait for the light to turn green. The most efficient driving involves never losing your momentum, which results in your right foot...

As far as I know, charging the battery to full does not reduce the service life of the batteries. I don't think that is what Don was talking about. I think Don was referring to the fact that if you charge your pack to full and then let it set for a few hours then it will have...

As far as I remember, it has always been recommended to never drive past 50% SOC. If you have the EV1Dash software, you can use your judgement which 50% SOC you care to heed, but they are relatively close enough to each other that you should hopefully be close to a charger whe...

Batt Life will light for a few different reasons, though the most common is triggered through too aggressive of driving style for the given state of charge. A timer is started within the BPCM on the first low volt event (usually acceleration), and accumulates until the volume...

Interesting. Most RV parks do have separate meters for each space. It's certainly true that some RV parks are not at all EV-friendly, but many RV parks are EV-friendly. Not all RV parks have 240V service. Some of the smaller and older parks have 120V service only. In RV park d...

I have found early morning charging (cool temps.) and only charging to 3/4 capacity will keep the A/C from going on. You might be able to use conductive charging and not worry about temperature issues if you follows these rules. However, you still have the "state of charge" in...

Hi, Joshua-- RPM means Reduced Power Mode. It'll go no faster than 25 on the level and it won't climb a decent hill. Quite a bother when it happens on the freeway, as it used to do often with our truck's old PbA batteries. Back then I had to go the long way around to get home...

Gentlemen, the S-10EV utilizes a sealed battery box with active refrigeration for pack cooling. Whereas the Rav utilizes passive cooling only. During charge, the S-10EV pack temperature is limited to 87 degrees F in order to maximize charge energy, efficiency, and battery cycl...

A quick telephone call to the manufacturer disclosed that their product probably *will not* work with the S-10EV. But you're welcome to buy it, and try it, and possibly eat it. Not likely they'll accept a return. That's why they want you to check the compatibility list first....
