Colder Weather Battery Endurance

[ssilverman21]

This will be the first Winter driving my Taycan. I’m already noticing a slight drop in the mileage Range when charging to 85% due to the colder temps. Is there an approximation (%)of how much the battery range is reduced in colder temps? And is the reduction in range simply bc the actual battery itself is cold, but as you drive the car and all of its components warm, including the battery, you will see the range normalize? I’m also always surprised by how much the range is reduced while heating or cooling the car.

It all depends. This past winter in the north east was very mild. In 30* weather, I was seeing 220ish miles at 100%(2.7-3.0mi/kwh). It was a bit better than this in the morning with a fresh charge and a warm battery. In the evening when the car is cold soaked sitting in a parking lot, expect less.

You can adjust for temperature on the range calculator:

The battery has less capacity when cold and acceleration feels worse to me too, so both a range and performance hit.
There is a 1 hour pre-heat function you can select from the app which warms the cabin and, I believe, battery which will help both range and performance.
The timer function prepares the car for use by getting the battery to a suitable temperature if it is cold. I believe this was added as a solution to the problem found in cold weather testing.

Heating and cooling the cabin are the only other functions that use non-neglibible amounts of power.

Battery temperature is one of the dash displays I keep an eye on.

I haven't done a definitive test on the Taycan but I lose about 20% of the hybrid range in our PHEV car in our relatively mild winter.

from post #8 of this thread - https://www.taycanforum.com/forum/threads/range-in-cold-temperature-weather.13561/#post-203486

range in the cold is affected by a number of factors that all add up to significant range reductions:

• cold air is denser increased drag - this increase is significant in terms of aero drag - speed being V^2 for drag will not help matters
• cold batteries have less power to give than warm batteries - your LiON battery is less efficient when it's cold - lowering your range
• cold weather tends to also have worse road conditions - increasing rolling resistances - it's more expensive power-wise to drive around on crappy roads…
• cold weather tires have more rolling resistance
• the vehicles will direct extra power power to warming the battery - taking that power from range
• more power will be used to keep the pesky occupants warm - heating the cabin is more expensive than cooling in mild/hot temperatures
• Fast Charging will be "less fast" - both the charging hardware/stalls will be slower and the Batterie's ability to accept fast charging will be reduced due to lower overall battery temperatures - expect longer fast charging stops.

given the factors above - 30% reduction is an expected outcome - until proven otherwise.

Many good things said here, just want to add:

You can largely mitigate cold weather by charging just until you leave.
The battery is then warm from the charging process and range normalizes, especially if you have a heat pump.
Use a charging timer setting for this.

Thanks for your response. Interesting ... a heat pump as in a heater in the garage where the car is being charged?

Negative. It's an actual heat pump in your car. It is required in some markets. U.S-yes. Check your build sheet.
