Check your vehicle's specifications or owner's manual for the official efficiency rating (Wh/km or km/kWh). You can also calculate it by dividing energy used by distance traveled over several trips.
Extreme temperatures reduce battery efficiency and require more energy for climate control. Cold weather can reduce range by 20-40%, while hot weather increases air conditioning usage.
A 20% safety buffer is recommended to account for battery degradation over time, unexpected trips, and to avoid range anxiety. Conservative drivers may prefer 30-40%.
Aggressive driving with rapid acceleration and high speeds can increase energy consumption by 20-40%. Efficient driving techniques can reduce consumption by 10-20%.
Yes, EV batteries typically lose 2-3% capacity per year. The safety buffer helps account for this, but consider your long-term needs when sizing your battery.
Yes, additional weight increases energy consumption. Every 100kg of extra weight typically increases consumption by 1-3%, so factor in regular cargo when calculating battery size.
