It's always good to keep your battery as cool as possible. Ideally, you would keep it at around 72F. Anecdotally, it's easy to "see" that the batteries don't last as long in the extremes - Texas, SoCal, Arizona, while they tend to last the longest in the northern latitudes. But individually, you still have packs that have lasted 14 years in AZ and packs that only lasted 3 years in Maine. There are a lot of variables, but given a big enough sample size, that's the trend.What can you say about the negative affects of heat on the battery? I have so far been able to keep it under 100. When does heat become an issue?
It sounds like you have this much more under control than most people. If you can keep your battery at under 100F during summer, that's a good thing.
The Ford Escape Hybrid implemented an AC System for the battery, and I have no doubt this has greatly contributed to their on-going excellent lifespans.
Hmm. I've always taken advantage of the manual nature to regen more than the car would at any given moment. I guess I've never thought too deeply about the potential side effects of this, mostly just focusing on that it allows you to maintain a higher SoC - even in the face of higher assist utilization.Also when using IMAC&C for Regen is there an amp range to stay under. I’m worry about hitting it with more than 30-40 amps for more than a few seconds. I try to mimic patterns I see the car naturally doing.
How you use the battery is all cumulative, it all matters and definitely has an effect on things.. ie: cycling a battery with a square waveform will cause different wear than a triangle, etc.
It's hard to weigh these miniscule effects though. From my point of view based on what I know right now, higher regen is good because that's when you get equalization. Imagine each burst of 50A of regen as a mini pack equalization, if you're at high SoC. If you're at low SoC, it's basically all absorbed.
