The optimal charging strategy for your EV

Kern-Prinzip: Intelligente Ladeplanung statt blindem Laden

The perfect charging strategy is based on three factors: vehicle model, charging column, and current battery temperature. LadeGuide automates this calculation for you.

1. The 80-percent rule explained

Most EVs reach their maximum charging power up to about 80%. Beyond that, the process slows down significantly due to the decreasing charging curve of the battery.

Batteriestand Ladeleistung Geschwindigkeit
0–50% Voll (100%) Schnellphase
50–80% Slightly reduced power Effizienter Bereich
80–100% Stark reduziert Inefficient – only when needed

2. Fahrzeugspezifisches Laden

Every EV has a different charging curve and a different optimal charging range:

🔋

Lithium-Eisenphosphat (LFP)

Valid for: Tesla Model 3 RWD, BYD Atto 3, NIO ES6

Range: Chargeable to 100% – no degradation.

⚡

Lithium-Ion (NMC/NCA)

Valid for: Most premium EVs (VW ID.4, BMW iX, etc.)

Range: Ideal 20–80% – easy on the cell chemistry.

🌡️

Kaltwetter-Modus

Valid for: all models at temperatures < 5°C

Range: Avoid range loss from cold: when needed preheat, ideally while charging.

🔥

Preheat the car

Valid for: all models in cold weather

Tipp: When the car is hanging at the charging column, preheat — the energy comes from the grid, the range stays intact.

3. Charging times in practical comparison (AC charging)

Charging point Leistung Dauer (10–80%) Typischer Einsatzort
At home (Wallbox) 3,7 – 11 kW (AC) 4–8 Stunden Eigenheim, Garage, Tiefgarage
Public AC column 3,7 – 22 kW 1,5–6 Stunden Einkaufszentren, Hotels
Tesla Supercharger (LFP) 150 – 250 kW (DC) 10–20 Minuten* Hauptverkehrsachsen
HPC Charger 250 – 400+ kW (DC) 10–20 Minuten* Autobahnkorridore
Megawatt (MCS) 1 – 3,75 MW (DC) 25–40 Minuten² Autobahnkorridore (E-LKW)

*Measured at optimal battery temperature and available grid power. ²Megawatt charging (MCS) today is primarily for large electric trucks designed.
