The cost of charging at County owned EV charging stations is $0.24 per kilowatt-hour (kWh) for all users. 

  1. All County EV charging stations and transactions are managed through the ChargePoint network. To use the EV charging stations, you will need to register and join the ChargePoint network.
  2. Once you are registered, you will receive a ChargePoint card in the mail, which you will need to activate. Detailed instructions to activate your card can be found on the ChargePoint website
  3. Once your card is activated, you can start a charging session by one of three methods:
    • Tapping your ChargePoint access card on the start screen of the charging station;
    • Using the free ChargePoint mobile app
    • Calling driver support at the toll-free number listed on each ChargePoint station and on the back of your ChargePoint card.
  4. If you are a County Employee, please visit this pdf to access to employee only stations. Employees are also welcome to join the conversation on our Yammer Page.

Please note, when you activate your ChargePoint account with your credit card, you will be automatically charged $25 by ChargePoint. When you start using the ChargePoint chargers, the charge fees start getting deducted from the $25 fund that is in your account. When your account runs low (under $10), ChargePoint will charge another $25 to your credit card. This way, your ChargePoint account will always maintain a balance. If you cancel your account, you will be refunded the remainder of your deposit.

You can find charging spots and check their availability using your mobile phone through the ChargePoint mobile app.

For more information on how to register for a ChargePoint card, please call the 24 x 7 technical ChargePoint support line at 1-888-758-4389 or visit

Safety First: Practice safe charging by properly managing the cord during and after charging. Avoid overstretching the cord, and ensure that the cord does not come in contact with other vehicles while charging. While your car is plugged in, make sure the way the charging cord is oriented so others do not accidentally trip or drive over it. If you have a plug-in-hybrid vehicle, make sure it’s not touching your exhaust pipe, which could be hot. Once your car has finished charging, remember to place the charging cord back into its holder.

Active EV Charging Only: An EV can only occupy a charging station while the vehicle is actively charging. Internal combustion cars are prohibited from parking in charge spots. As soon as the charging session is completed (i.e., your battery is full or when you have enough range to reach your destination), please unplug your EV and move it to an appropriate non-EV designated space to allow charging access for another driver.

Use Only When Needed: Please refrain from charging your EV if you don’t need a charge to get your next destination.

Unplugging Other EVs: Please do not unplug other EVs as it may disrupt charging or cause damage.
