Charging Networks

Start with David Herron's article What charging networks exist? ChargePoint? Plugshare?

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 (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.

If you're traveling, ChargePoint should be the first mobile app to check while planning your next trip leg.


PlugShare is not a charging network, but an information-sharing service for EV owners and those making their 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.

EVgo (US)

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.

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.

David Herron's Charging Etiquette covers a great deal of the issues involved with EV charging as a social problem.

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."

Other EVs

Here are some scrounged notes on how to deal with other EVs by model.

Generally, you want a field guide for whether the vehicle is actively charging or done charging, so that you don't interrupt a charge, but can also get a charge without inconveniencing a stranger.

Some stations share capacity, so knowing the default charging rate of the other vehicle at a station helps determine whether pairing will work.
