Why is average charging power more useful than peak power?
Two cars advertise different maximum DC charging rates. What additional information is needed to compare how long a useful stop will take?
EVVerity explains
A closer look
Calculate from the whole session
If an illustrative session delivers 42 kWh in 30 minutes, its average delivered power is 84 kW. A brief peak above that does not change the half-hour stop. Compare an equivalent charge interval under comparable conditions rather than comparing only the highest number.
Keep test conditions attached
Starting charge, battery temperature and charger capability can change a charging session. Ask whether the comparison uses the same start and target charge and whether the battery was prepared. A peak specification alone is not a full charging curve.
Include time off the road
For journey planning, add the detour, possible queue, connection and payment time. A faster energy transfer does not always make the shorter overall stop. Keep those practical assumptions explicit instead of hiding them inside an optimistic charging-time figure.
