How to use ChargeWindow

ChargeWindow is for the planning moment before departure, when you want a calmer answer than “we will probably find a charger”. Enter the trip facts you know, tell the tool how defensive you want to be, and use the result as a practical pre-drive brief.

What to enter

  1. Trip distance: use the real door-to-door distance for the leg you are planning.
  2. Real-world range at 100%: use the number you genuinely trust in current conditions, not the most optimistic brochure value.
  3. Starting battery and arrival reserve: tell ChargeWindow how much battery you expect at departure and how much cushion you want on arrival.
  4. Weather, speed, and terrain: these are the three biggest practical range-shrinkers for normal drivers.
  5. Charger spacing and confidence: this is how the tool decides whether one charger is enough or if the day needs more buffer.

How to read the result

  • Recommended posture is the overall travel style that best protects the trip.
  • Estimated safe reach is the planned battery window after weather, speed, terrain, and arrival reserve are applied.
  • Stop windows tell you roughly where a charging pause should happen if the plan needs one.
  • Reserve guardrails explain what behaviour keeps the plan calm once the trip starts.
  • Copyable road brief is there so you can paste the plan into a message or keep it in your notes.

Best use cases

  • Weekend drives where one unreliable motorway charger could make the whole family anxious
  • Business or airport runs where you need to know whether one stop is enough
  • Winter or rain-heavy trips where your usual range assumptions feel shaky
  • Any drive where a calmer plan is more useful than over-confident optimism

Important limits

ChargeWindow does not know live charger occupancy, broken plugs, live traffic, trailer load, or tyre pressure. Treat it as a planning brief, then verify the actual route and charger status before departure.
