Does DC destroy the battery's speed charge? Less than you think - with one exception

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.

The frequent charging of high DC power according to the updated study Geotab 2026 may be related to faster ageing. This does not mean that a single charge on the long distance will damage a particular car. When charging normally at home, use the power sufficient for your needs; on the route respect battery control and manual. Current primary source.

The one exception: frost

Quick charging cold batteries (below ~ 5-10 ° C) is actually harmful - there is a risk of lithium plating, irreversible elimination of metal lithium on the anode. Therefore: in winter always preheat (navigation on the charger or preheat function) and don't worry that the frozen car takes the first 10 minutes just 30-50 kW - BMS protects you.

Why on the route charge only up to 80 %

Charging power with increasing SOC decreases (protection of cells): the last 20 % often takes longer than the previous 50. Therefore, the highway is faster strategy 10 → 70-80 % and drive on - That's exactly how it counts. plannerwhich knows the charging curves of the car.

Paper vs. real station performance

The station "250 kW" gives you 250 kW only with low SOC, hot battery and when you don't share the performance with the neighbor. Really measured performance (car +% battery) - you will find them on the station detail on map.
