Electro-mobile in winter: what frost does to the battery and how to outsmart it

Part of the Guide Electro-mobile batteriesAre you choosing a car? The battery chemistry of specific models can be found in catalogue of electric cars.

In the cold the battery does not lose capacity - loses willingness to publish itChemical reactions in the article run at -10 ° C laziness, with you drowning the cabin. Result: real range typically 60-75 % summer, at -15 ° C and short routes even less.

Preheat is 80 % success

1. Preheat the car before driving. connected to cable - you're drowning from the net, not the battery. 2. Before charging always Activate the preheat of the battery (the navigation on the charger triggers it automatically) - the cold battery takes 30-50 kW instead of 150 +. 3. The heat pump makes the difference in winter 10-20 % range - when choosing the car look at it.

LFP in freezing cold

LFP is more sensitive to the cold than NMC: more down in power and regeneration and less preheating charges significantly slower. It does not mean that LFP does not belong in winter - only more depends on preheating and planning. planner has a riding style / winter supplement consumption for it.

Winter Nineteen

Park in the garage or at least charge right after driving (the hot battery takes more). Do not leave the car in freezing on low SOC. Regeneration is initially limited - count the longer brake distance "on the pedal." And most importantly: plan the winter run with reserve 25-30 %, not 10.
