Good call. Save yourself the stress and focus on enjoying your awesome ride. The best way to begin doing so is by changing the display so that it shows percent instead of miles. Everyone should do this now and just forget about what the Guess O Meter thinks it has available in terms of...

That's a confusing way to think about it from my perspective, after all, a 1C charge rate takes longer than an hour because you're referring to the peak rate only.. The time it takes to refill the batteries' full capacity is dependent on the size of the top buffer. The C rate is purely how fast...

C-rating is used to describe the charging/discharging profile of a battery, where C is the capacity (usually in amp-hours, but it is often described in kWh as well). So if you refer to a 1C charge rate, and you're dealing with a 100kWh battery capacity, your charge rate will be 100kW. 2C would...

+1 From my experience, this is due to the effect that temperature has on the SoC. For example, after completing a charge at 10kW, the pack will have an increased temp which raises the SoC from the BMS’s perspective, and there‘s probably a delay in the max pack temp after the charge stops due...

‘Reassuring’ is better, but even that still implies that this number holds some weight when evaluating range, which I argue it does not. Lithium batteries simply do not degrade at this rate, unless exposed to some outside influence (extended high temp exposure, extreme deep discharge without...

It makes me cringe when we refer to this number as being 'really good.' Suggesting that this number is either good or bad is very misleading as it is almost meaningless and should never be used to evaluate.. anything.

The range reported on the dash is just a guess and does not represent what you can expect after considering how you drive, weather conditions, etc. As mentioned already, the best way to understand how much range you can expect is by factoring in your average rate of consumption and do the math...

Whenever I‘m away from my Tesla for a longer period of time, my main concern is the possibility of depleting the battery if it’s unable to charge. This would be devastating to the battery if left depleted for more than a few hours. This is why it should be left plugged in, with a charge set...

I‘ve definitely thought about swapping the 12v out for a lithium solution, but they’re still quite expensive and, as others have mentioned, are not yet refined enough to survive all of the extreme conditions that the car and lead acid battery can. Lithium batteries have been available for...

Good call. Climate certainly plays a factor in how long they last. The point is, change it as a preventative maintenance item at whatever interval makes sense for your usage/climate, do not wait for the EV to tell you that it needs replacement as it will always be too late when this occurs.

Having gone through this before with my i3, I can confirm that it was quite scary with my entire family in the car. Unfortunately, until this happens to you, you won't understand just how impactful it is when the 12v battery fails in an EV, especially while driving and without any warning. The...

The goal should be to cycle the pack around 50% SoC. Depending on how much you drive the car will determine where your charge setpoint should be. For example, I only drive about 25 miles round trip every day, so I've got the charge setpoint set to 60-65% generally. I would then plug it in once...

I’m not disagreeing at all with that. I guess you’re not understanding how I choose to explain it. From my perspective, you’re basically repeating/reinforcing what I already said about voltage. Feel free to try and explain it better if you get what I’m saying.

Agreed. Each unit of measurement is intended for different types of circumstances/applications. Voltage is obviously important to know in order to have a holistic understanding of a battery or power system. The confusion begins by not recognizing when it's appropriate, and when it isn't, to use...

If anyone is not familiar with who Bjorn is, you should take a second to watch some of his videos on YouTube. He does a great job evaluating various EV‘s from all manufacturers and he is not shy about getting into the details. He has multiple videos that go over degradation tests, the process...
