This is a calculation example, not a claim about a particular car. Assume 60 kWh of current usable capacity and ask what a 20–80% charge adds before electricity prices and losses are considered.
EVVerity explains
The charge interval is 60 percentage points. Multiplying 60 kWh by 0.60 gives an estimated 36 kWh added to the battery. Use current usable capacity if known, and recognise that displayed charge percentages and capacity estimates introduce uncertainty.
At an illustrative 90% charging efficiency, the estimated input is 36 ÷ 0.90 = 40 kWh. This is not a universal efficiency assumption. A receipt or dedicated meter can give you the actual billed energy, which is the better starting point for the cost of that session.
At an example price of 0.25 currency units per kWh, 40 kWh costs 10 currency units before additional fees. Replace the example price with your tariff and include parking, connection or idle charges where applicable.
