Models the charging curve: which EV planners do it

Does it know your car charges slower as the battery fills?

Why this one matters

A car that takes 18 minutes from 10% to 50% can take another 25 to reach 80%. A planner that ignores this sends you to fewer, longer stops and gets the arrival time wrong in a way that compounds over a day.

The gaps in this row

We could not confirm models the charging curve for Apple Maps, Chargemap, Drive Charge Eat, Zapmap from their own documentation on 2026-08-19. That is a gap in our checking, not proof the feature is missing, and it is marked rather than filled in.

What to do with this

If you need charging-time estimates that hold up, the shortlist is A Better Routeplanner and Tesla in-car navigation. If you do not, ignore this page — a capability you have no use for is not an advantage.
