5 kWh Battery Backup for Cars: Is It Worth It?
A typical electric vehicle's energy consumption varies significantly depending on the model and driving conditions, usually ranging between 15 kWh/100 km and 25 kWh/100 km.
For this analysis, we assume a moderate energy consumption rate of 20 kWh per 100 kilometers. Using a 5kwh battery as a supplemental power source, we can calculate its potential range extension. The formula to calculate the required energy for driving 40 kilometers is:
● Required Energy = (Energy Consumption per km) × Distance = (20 kWh / 100) × 40 = 8 kWh
In summary, if your electric vehicle consumes 20 kWh/100 km, you would need approximately two 5kwh solar battery units to cover a daily 40 km commute. A single 5kwh battery alone would not meet the full energy demand for this distance.
