EV route planner

Use the Zap-Map route planner to plan suitable charge stops on your electric journey. Default to the standard settings for a ‘quick plan’ or adjust the driver and charger search options to create a customised route plan.

The route planner is currently available on the Android app (4.0) on Google Play and will be available on the iOS app on the Apple App store later in the summer. We welcome feedback or questions on any aspect of the route planner.

Below is a step by step guide to the Zap-Map Route Planner v1, showing selection options and methodology, with a step-by-step video at the bottom of the page.

Step 1 – Enter Route

april 10 2017

Use the search box to add your starting position and destination and any waypoints required.

You can select your current location, Zap-Home or Zap-Work point if available, and you can also see recent search history.

Step 2 – Quick plan options

april 10 2017

Create a ‘quick plan’ based on your EV model and system defaults. Alternatively edit battery, charger search and filter options to create a customised route plan.

EV Model: it is mandatory to have an EV Model set-up to use the Route Planner, so if you haven’t already, you will need to add it here. You can change or update the EV model and it will save to your account.

EV range figures: the official NEDC and estimated real-world range for your EV model is shown. You can edit the real-world range to reflect your experience. This will be used as an input into your estimated drive range.

Rapid only (default): this will filter your charger selection to only show rapid chargers compatible with your selected EV Model. If your EV Model cannot rapid charge the selection will change to “Fast only”. Deselect to select all connectors compatible with your EV; select specific connectors within Driver Options.

Suggest chargers = Y (default for BEV): the system will suggest chargers closest to your estimated drive range based on your Charger Search criteria and Filters. You can edit criteria in Driver Options; if no changes made, the default values will be selected.

If Suggest chargers = N (default for PHEV): then the system will show you all the chargers along the route based on your Charger Search criteria and Filters. You can edit criteria in Driver Options; if no changes are made, the default values will be selected.

Step 2 – Battery charge & charger search options:

april 10 2017

Edit battery charge and charger search area options as required to reflect your situation.

Battery charge:
% charge at start: this is the percentage to which the battery is charged at the beginning of the journey. The default value is 100% for the initial leg, the minimum value is 5%. For subsequent legs, the system defaults to 100% charge.

% charge at end: this is the level of charge that you do not want to go below before you charge your car – your safety buffer. The default value is 20%. This value must always be 5% below the % charge at start.

Charger search options:
Distance from route: this is the distance that the system will search for chargers. The default is 1 mile, but can be set to 10 miles from route.

Distance from max drive range: this is the distance back along the route from your estimated drive range that the system will search for chargers. The default is 20 miles, but it can be set to up to 50 miles. Due to differences between marker distance, the actual search area may vary from input.

Number of suggested locations: this is the maximum number of chargers which fit the search criteria that will be shown on the route for each leg. You can then select the most appropriate. The default value is 3 and the maximum chargers shown is 10.

Step 2 – Filters

april 10 2017

Filters: Use the system defaults or select connector and network filter options.

Connector type filters: this shows all the connectors which are compatible with your selected EV model. Default is set to Rapid Only or Fast Only.

Network filters: this shows a list of all networks. Select the networks which you would like to include on your route plan. Default shows all networks.

Drive Range: This is the estimated maximum distance that you can drive for each leg. It is estimated from your EV real world range, battery charge options with some adjustments for average speed (for each leg) and route elevation (across whole route).

Average speed: This is one of the most important factors which determine EV range. We make adjustments to the drive range for average speed on a particular leg over 50 mph. As range is seen to drop significantly at higher speeds, the route planner is based on an expectation of max speeds of 60-65 miles.

Elevation: This is a factor which impacts drive range. An elevation factor for the whole route has been included in the route planner. As this is not based on a specific leg, if there is a steep incline within one leg, you should adjust your range expectations.

Step 3 – Select Route

april 10 2017

Select your preferred route; if the route you would like is not shown, go back to Enter Route and add a waypoint. The system will suggest up to two alternative routes and show distance, time, average speed and estimated energy use for each option.

Time: this is the expected journey time excluding charge stops based on driving at the UK speed limit.

Distance: this is the total route distance in miles taken from Google API.

Average speed: this is calculated from Time and Distance.

Energy use: this is estimated from the EV Model real world energy use figure, with adjustment for average speed and route elevation. No energy use figure is shown for PHEVs, as only a proportion of the journey will be made in electric mode.

Step 4 – Add charge stop

april 10 2017

From charging locations shown, choose which charge stop(s) to add to your plan.

Suggest Chargers = Y: a cluster of charge points nearest to your estimated drive range, based on real world range, battery charge with some adjustment for elevation and average speed will be shown. See ‘i’ tab to review estimated drive range for each journey leg.

Suggest Chargers = N: all chargers along the route that fit charger search and filter options will be shown.

Add a charge stop: Click on a marker to see information about the charge point on the charge point placecard.

View drive range Click on the ‘i’ button to see estimated drive range for this journey leg.

No chargers available: if there are no chargers on your route based on your selections, the system will give you the option to expand the charge search area, and then if still no chargers it will suggest you edit your Driver Options.

No charge stops needed if the estimated drive range is longer than the journey distance, the system will let you know and give you the option to show all chargers on the route or go back and edit Driver Options.

Step 4 – Placecard:

april 10 2017

Click on marker to view charge stop information and add to route as necessary.

Distance: shows the distance from starting point or beginning of that journey leg.

Arrive % charge: shows the expected amount of charge remaining when reaching the charge stop.

Charge point details: shows the charge point name, postcode, network, devices and connectors, location status. Time indicates last time the status was updated.

Add to route plan: the charge stop will be added to the route plan and then, if needed, the cluster of suggested charge points for the next leg will be shown.

Remove from route plan: the charge stop will be removed from the route plan, and the cluster of suggested charge points for that leg will be shown.

Step 5 – Route plan

april 10 2017

Check, view, and/or edit your route plan in map or list mode. When you are satisfied with your plan, save the plan using default or chosen name.

Viewing route plan: the route plan can be viewed as a list or on the map.

Editing route plan: If you select edit you can go back to Step 4 and edit the charger selections and use the back buttons to edit Select Route, Driver Options, and Enter Route.

Saving route plan: Your route plans will be saved within the Account section under “Your route plans”. You can save a maximum of 3 routes.

Step 6 – Retrieving route plan

april 10 2017

You can retrieve, view and edit route plans from the Your route plans area in the Account section. When you retrieve a route plan it will update route and charge stop status information.

Navigating to charge stop: You can navigate to the next Charge Stop by clicking on the navigate arrow and it will punch out to Google Maps / Apple Maps.

Deleting route plans: You can delete routes by swiping left in the “Your route plans” section in the Account menu.

This is v1.0 of the Zap-Map Route Planner, the next version will incorporate more features. We welcome any feedback or questions. Please email us on contact@zap-map.com.


While we have worked hard to ensure the Route Planner selects suitably located chargers along your route, many factors impact drive range and charger availability, some of which are outside our and the driver’s control.

As a result, we advise that the figures provided by the Route Planner should not be relied on in isolation but rather be used as a helpful guide and used in conjunction with other available driving information.
