For example, if your electric car has a 50 kWh battery and is 30% dead, it will require 15 kWh of energy (50 kWh * 0.3) to fully charge. This indicator may depend on the electric vehicle model, its battery, temperature conditions and other factors. Typically, electric vehicle manufacturers list charging efficiency as a percentage.
The answer to the question of how many kilowatts you need directly depends on the car model, its battery capacity and charging technology. The larger the capacity, the more electricity is required to fully charge. For example, an electric car with a 60 kWh battery will require more energy than one with a 40 kWh battery.
It’s generally recommended to avoid charging to 100%, except for long trips. For everyday use, keeping the battery charge between 20% and 80% helps preserve its lifespan. ↪️ Read more about:
This capacity directly determines the vehicle’s range, meaning the distance it can travel on a full charge. For example, an electric car with a 52kWh battery can cover approximately 400 kilometres, depending on its energy efficiency (average consumption in kWh/100km). However, this range is influenced by several factors ⬇️.
For everyday use, keeping the battery charge between 20% and 80% helps preserve its lifespan. ↪️ Read more about: Should you charge your electric car every day? Do fast charges affect the lifespan of an EV battery?
To charge a car battery, the required kilowatts depend on its capacity. For instance, a 100 kWh battery needs about 100 kW to fully charge in one hour. Factors like charging time and energy consumption can also affect the total kilowatts needed for the charging process.
