We now know our vehicle needs 70kW to achieve a full charge and our charger, is charging at the rate of 7kWh.
Now it’s just some simple maths. 7 (kWh) x 10 (hours) = 70kWh, it really is that simple!
Now you know it takes around 10 hours to charge a 70kWh battery, you know it will take over 10 hours to charge any battery higher than 70kWh and less than 10hours to charge any battery lower than 70kWh.
Want the excruciating details and minutes?
70kWh is easy to work out! Let’s assume your battery is 54kWh which is a figure we’ve concluded as a rough average across 40 of the best selling EV’s.
The maths is the same! Find the nearest whole number, 7 (kWh) x 7 (hours) = 49kW of charge. At this point, we know this particular vehicle would take over 7hrs, though less than 8hr’s, to achieve a full 100% charge.
Not accurate enough? If you would like to know the extended minutes. Take the remaining 5kW required to hit (54kWh), divide by 7kWh and times by 60 minutes (5 ÷ 7 x 60) which equals 42 minutes.
There we have it, to charge a 54kW battery it would take around 7hr’s 42 minutes!
Voila! the average time to charge an EV is around 7 hours 42 minutes!
