Charging Information
See also Zero Aftermarket Chargers
Start with David Herron's article What charging networks exist? ChargePoint? Plugshare? and the Wikipedia article on Charging Networks
- Finding Stations
- Benswing Rich has a lot of experience with finding charging at RV parks- see his videos on Youtube about his rides across the USA.
- With regards to finding reliable J1772 "J-Plug" stations, he says:
- ChargePoint is definitely my favorite. In large part because I can track charging via their app. That way I know when my charge is done or has been interrupted.
- I rely on PlugShare reviews to inform me which stations are unreliable and that has worked well for me.
- I also like ClipperCreek, Inc. chargers and SemaCharge because they sometimes are higher powered (7.2kW).
- Problem stations (for Elcons) were old style GE Wattstations (the new ones work fine) and Eaton. But I think both work with the Supercharger v2.
- Blink stations have a 50% success rate over 4 years of long distance journeys, so I avoid them like the plague. Also, they are underpowered even when they work.
- Chargepoint, Volta, and Semaconnect are networks that show you whether a station is in use or available before you get there.
- Semacharge/Semaconnect: https://network.semaconnect.com/mobile/#map
- Volta does not show status on the web, just the app.
- Chargepoint shows its own, Blink, SemaConnect, and eVgo stations https://na.chargepoint.com/charge_point
ChargePoint RFID tags are worth having; they let you activate free non-networked stations (many owners decline to renew with chargepoint) https://na.chargepoint.com/register
E-Touring meta-map
Togo has started a Google MyMaps collaborative with links to plugshare. The goal is to include the best 2-3 locations in each area. Unless they are the only stations in town, omit the car dealers, the onesie stations, the poorly maintained ones, the limited hour locations. Contact via EMF for collaborator status to add the stations in the areas you know.
PlugShare (US/Canada) is an information-sharing service/website/app for EV owners, EV Networks, and those making their home EV chargers available to the public or on a request basis.
Their service is very good for cross-service discoverability and a certain amount of basic route/travel planning.
The filter feature is good at pulling out the good vs the bad, for example, showing just the J-plugs (if you have rapid charging) or just the Wall outlets (if you are have slow charging and are looking for a destination to be a while).
A particularly useful feature of PlugShare is its ability to Check-In and to see whether other EVs have had success or failure charging recently.
ChargeMap
ChargeMap is a service similar to ChargePoint for finding stations on various charging networks, especially in Europe.
Their service is very good for cross-service discoverability and a certain amount of basic route/travel planning and their Pass which does payment for several charging networks.
EV-Charging
EV-Charging is a site and an app focusing on Europe. It shows very few stations in some countries, like Italy and Greece.
RV Parks and Campgrounds
Various apps exist (for the US), such as RV Parky.
- Fee Rate Problems
- RV park owners are accustomed to renting their spaces to large vehicles for days at a time with high but variable power demands.
- Typically, they'll charge between $15 and $25 USD for an overnight stay.
- Most owners approach the EV charging question as a variation on this fee schedule.
- If you walk into an RV park office and ask to charge, they'll quote a figure like $10 or higher.
- For an electric motorcycle, this is an absurd figure, a markup of usually 1000% over the cost of electricity.
- Negotiating Problem
- The RV park community is generally not aware of some basic facts we live with:
- Electric motorcycles exist.
- How small the battery is compared to any electric car.
- You'll be able to charge in less than an hour.
- Explaining all of this wastes precious charging time and might irritate them.
- Suggested Approach
- Don't call ahead unless absolutely necessary; this allows them to frame the discussion in terms of their by-the-book rates.
- When walking up to the owner or employee, the only phrase out of your mouth should refer only be:
- I'd like to plug in for less than an hour and use maybe 8-10kWh of electricity.
- Pause to let that sink in and let them look at your vehicle while they grasp how small the request is, and how they aren't risking losing a larger customer.
- This sidesteps a lot of negotiation and let's them feel like they're being generous by asking for a smaller fee or waiving it entirely.
Charging Networks
ChargePoint (US)
ChargePoint is a large EV charging network with good reliability, and particularly an excellent software service for knowing whether a station is working and taken before you arrive, queuing to use a station, and for monitoring a charge remotely while your EV is using a station.
ChargePoint stations are often found in rows at major shopping centers, which is convenient for those who have dual-J-plug rapid-charging capability.
Prices for ChargePoint stations are set by location, and vary widely, and may be priced per hour, per KWh, or both.
SemaConnect
SemaConnect seems to be common in smaller towns, such as Watsonville, Seaside, Carmel Valley. Prices for electricity are often as much as 3X the retail price (e.g. Gilroy) but are sometimes free (downtown Watsonville).
EVgo (US)
NRG EVgo highlights their DC fast charging which is inaccessible to Zero owners for now. Their AC charging is relatively reliable, but as a second tier service, it does not get the attention that the DC charging gets, so your experience may vary. Usually the AC charging stations are at opposite ends of the row, making Dub-J charging difficult.
Blink (US)
Blink is an early EV charging network startup company that had reliability and rollout troubles. Their chargers often work serviceably but with low power capacity in the 3kW range with a mis-calibrated J1772 signal.
SunCountry Highway
Southern Canada coast to coast, and scattered high-amp J-plugs and T-plugs in other places.
Primary website does not seem to have a station locator, but mobile site does: [[1]]
Greenlots
Mostly remote towns, e.g. [Fortuna]. Can activate by swiping a credit card, or get an account. There's an app too.
Regional Networks
coastal Oregon and Washington: West Coast Electric Highway aka Aerovironment aka AV aka evsolutions-
$19.99/month gives you unlimited charging, or you can pay $4/session, a pricing scheme that results in station-hogging by large-battery vehicles.

Mobile Apps
- Cellular Access Notes
- Cellular connections on the road can be poor, and cell batteries run down rapidly in poor-connectivity areas.
- It is wise to locate and mark potential charging sites before you depart, while you have a good connection, and to carry phone-charging equipment along, such as 12V SAE-to-USB or SAE-to-cigarette-lighter-to-USB adapters.
- Charging on the motorcycle uses very little power in comparison to riding: charging a phone will hurt your range much much less than other factors such as speed, riding position, and tire pressure
- Offline Maps
- Google Maps
- Allows rectangular areas of your choice to be downloaded in advance of the trip, and allows .
- HERE WeGo
- Allows pre-downloads for offline use by whole states or countries.
- Has offline routing capability if the map has been preloaded.
- Planning Apps
- Apps that tell you if a station is in use before you get there:
- ChargePoint
- Volta
- SemaConnect
Apps that find stations on various networks with some or no indication of availability:
- PlugShare (shows availability for a very few networks) (also offers activation and payment for some networks)
- PlugSurfing (Europe)
- ChargePoint shows their own stations, but also Blink, SemaCharge, eVgo, and AV stations
In addition to the apps mentioned above, please see David Herron's excellent article on the subject.
Etiquette
- Overview
- David Herron's Charging Etiquette covers a great deal of the issues involved with EV charging as a social problem.
Charging Tags
- Take Charge And Go Hangers
- "Take Charge and Go EV Charging Hangers are an excellent way to indicate to other Electric Vehicle drivers know how long you will be charging and to share proper etiquette. Simply plug your car in with the hanger on the charging port or dashboard of your car and let others know when you can share the spot."
- Take Charge And Go Etsy shop with bundled packs of tags
- EV Frisbee
- Put this on your "dash" to give contact info and basic charging estimates for others to notice.

Equipment
Review various EVSEs by manufacturer and model...
Troubleshooting
Typical EVSE safeguards include RCD and GFCI.
A typical J1772 station will trigger a fault at 30mA of imbalance between L1/L2. Sometimes this applies to a ChargePoint-built station with a level-1 charging outlet when connecting both the level 1 and level 2 outlets to the same EV, but this is an EVSE implementation problem with the wiring, not inherent to such designs.
