EV Planner Compared

Explainer

Why two planners give the same car a different answer

Same car, same route, same day. One says three stops and six hours, the other says two stops and five. Neither is lying — they disagree about things that are genuinely uncertain.

They assume different speeds

Aerodynamic drag rises with the square of speed, and the power needed to overcome it with the cube. The gap between 110 km/h and 130 km/h is therefore not a twenty percent difference in consumption; it is much larger. A planner assuming you will sit at the limit and one assuming you will drift below it are modelling two different journeys.

Most tools let you set this and most people never do. If two planners disagree and you can only check one thing, check the assumed speed.

They model the charging curve differently, or not at all

A lithium-ion pack accepts high power at low state of charge and tapers steeply as it fills [3]. The practical consequence is that the last twenty percent of a charge can take as long as the first fifty, so the optimal strategy is usually more stops, each shorter, rather than fewer and longer.

A planner that models this properly will produce an itinerary that looks inefficient — four stops instead of two — and will nevertheless get you there sooner. A planner that treats charging as a flat rate produces a tidier plan that is wrong.

They disagree about the weather

Cold reduces usable range and simultaneously slows the rate at which the pack will accept charge [4]. Both effects push in the same direction, and a plan built on mild-weather consumption can fail in a way that a small error margin does not cover.

This is the row where the difference between planners is most consequential, and it is why the capability table treats weather modelling as a first-class feature rather than a nicety.

They disagree about how frightened you should be

Arrival buffer — how much charge a planner insists you have left when you reach a stop — is not a physical quantity. It is a policy. A tool set to arrive at 10% and one set to arrive at 20% will produce materially different itineraries from identical inputs, and neither is incorrect.

Range anxiety is a well-documented influence on how drivers actually behave, distinct from what the car can do [5]. A planner that lets you set this is letting you price your own nerves, which is the right place for that decision to sit.

What to do about it

  • Set the speed assumption to what you actually drive, not what you intend to.
  • On a cold day, plan with the pessimistic tool and treat the optimistic one as a best case.
  • Trust a planner that gives you more, shorter stops over one that gives you fewer, longer ones.
  • Re-plan mid-journey rather than at the start. Every input has drifted by then.
