EV Route Planner

How to use the EV Route Planner

It estimates how much battery your trip will use, shows chargers and road types along the way, and how long the driving takes. Everything is an estimate, so use it as a guide.

Quick start

1. Choose From and To. Type a place and pick it from the list, or tap Pick and then tap the map, or choose Use my location, or type coordinates like 28.2058,83.9734. Swap From / To reverses the trip. You can also paste a Google Maps directions link in the link box under them to fill From, To and any stops in one go. Use the long link from the browser address bar (it starts with https://www.google.com/maps/dir/); the route is then calculated again here, so the distance can differ a little from Google.
2. Stops in between (optional). If the route takes a different road from the one you use, open this and add towns it should pass through, one per line.
3. Set your battery. Start battery is how full you leave. Reserve is the lowest level you are comfortable reaching; you get a warning if the trip goes below it.
4. Plus codes. Google Maps plus codes work in From, To and Stops. Use the full code (8 characters before the +, like 7MW56X5P+R6) or a short one with a town after it (like 6X5P+R6 Pokhara). The result shows the plus code of each end.
5. Choose what to include: Return trip, Chargers, Road types, the chart and climb table, and Adjust driving time. Turn Road types off if you want a faster result.
6. Tap Plan trip and wait a few seconds. Long routes take longer.

Reading the results

• Outbound / Return tabs. The return trip is planned separately, on the way back. It starts with the battery you arrived with, unless you type a Return start % (for example 100 if you charge at the destination).
• Summary boxes. Distance, driving time (this does not include charging stops), total climb and descent, start and arrival battery, and the lowest battery point.
• Orange warning. The battery drops below your reserve at about a certain km, with the nearby place name and time when it can be found. The last charger before that point is shown. If there is none, charge earlier or start fuller.
• Chargers table. Distance along the route, driving time from the start, estimated battery when you get there, and the station name. (plug unverified) means the listing does not say which plug it has, so check before relying on it.
• Chart. Green line = battery, grey line = elevation, dashed red line = your reserve, pink band = unpaved road. Short black marks along the bottom are chargers.
• Climb and descent stretches. A table of the long ups and downs (30 m or smaller changes are hidden): where they are, the height change, steepness, driving time, energy used or recovered, and the battery at each end. A total of energy used is shown under it.
• Map. The route is coloured by road type or surface (change it with Colour route by). Tap a charger marker for details.
• Downloads. KML opens in Google Earth or Google My Maps. CSV opens in Excel or Google Sheets.

Road types explained

These come from OpenStreetMap and show how important a road is, not how good it is.

Surface. Paved or unpaved comes from the map. Where the map does not say, main roads are assumed paved and tracks unpaved, and the page tells you how many km were assumed. Tertiary and smaller roads are where unpaved or rough stretches are most likely, so read Check before you go.

Settings you can change

• Charger plugs. Fits + unknown shows chargers with a compatible plug (CCS2 or Type 2) plus those with no plug listed. Fits only hides the unknown ones. All plugs shows everything.
• Car and model settings. Battery size, energy use per km, how much energy you get back downhill, and vehicle weight. The defaults suit a Tata Punch.ev; change them for your car. A higher Wh/km makes the battery drain faster in the estimate.
• Adjust driving time. The routing service often gives a time that is too short on hill roads. When this is on, the time grows for climbs (about 1.5 min per 100 m climbed), for unpaved and rough roads, for traffic (Light, Typical or Busy) and, if you choose, for rest breaks. These are rough rules of thumb, not measurements. Turn it off to see the routing service's own time.
• Sample every km. How often the route is checked for height. 2 km is a good balance.

Good to know

• Real range depends on speed, load, air conditioning, temperature, tyre pressure and traffic. Keep a safety margin.
• Chargers come from chargingstationsnepal.com. A station may be offline, busy or closed, so check before you rely on it. Only chargers within 1 km of the route are shown.
• Driving time is for driving only. Add the time you need to charge.
• Long routes take longer to plan, mostly because of road types: about 10 seconds per 100 km of route. The return trip reuses the same route, elevation and road data in reverse, so it adds almost no time. The page tells you the expected wait for long routes.
• Your last settings are remembered on this device.

If something goes wrong

• "Place not found." Try another spelling, use Pick on the map, or type coordinates.
• "Short links cannot be opened here." Open the Google Maps link in your browser first, then copy the long address from the address bar and paste that.
• The route uses a different road. Add towns under Stops in between.
• "Elevation service busy" or a slow result. The free map services can be busy. Wait a minute or two, or try again.
• Road types unavailable. The road data service did not answer. The rest of the plan still works; try again later.
• No chargers shown. There may be none within 1 km of the route, or the plug setting is hiding them. Try All plugs.
