How to calculate the charging time of electric vehicles?
When you are thinking about purchasing an electric vehicle for your business or personal use, one of the doubts that arise is about charging and the time it takes to reach 100%. In fact, the charging time varies according to the battery capacity and the energy source. Therefore, in this article we will show you how to calculate the approximate charging time of electric vehicles.
To calculate the approximate charging time you just need to do a simple mathematical operation and for that you need to know the battery capacity in kWh and the power of the energy source in kW:
Charging time = Battery capacity / charging power.
For example:
If the battery capacity is 70 kwh and the charger charging power is 7.4 kW the time to charge from 0% to 100% would be between 9 to 10 hours approximately.
Currently there are fast, medium and low speed chargers. These can range from 7.4 kW to 50 kW, even in some cities are already being implemented fast chargers that can reach 100 kW.
Remember that battery life depends on the use you make of the vehicle: the use of air conditioning, connected devices, use of the entertainment center and engine stress may influence it. However, the recommendation to take care of the state of the battery is to maintain the charge at no less than 20%.
Another point to keep in mind is that you do not need to have the battery at 100% to use the vehicle. The autonomy of electric vehicles can vary from 300 km to 500 km with a full charge and they have a dashboard that shows the approximate range according to the charge level, which calculates the kilometers you can travel before the battery runs out. Therefore, the charge also depends on the type of use you want to give to your electric vehicle.
