    Anyone have recommendations for workplace EVSE units? Want 32 A charging at least, and a lock. The lock is important as we would get freeloaders otherwise.

    Reliable and cost effective. Don't need any fancy features.

    ClipperCreek offers an option called "ChargeGuard" which is a lock for the charger and can be ordered with any of their HCS models. It only costs an extra $78. The downside is you have to make a key for everyone that may need to use the station:

    For a higher-end unit, the JuiceBox Pro 40C is a great choice. It has authentication to eliminate unauthorized use, it has a tough aluminum outer casing (the only charger that has a metal case which is better for long-term outdoor use), and it can deliver up to 40 amps, which will be helpful for EVs like Tesla that can accept more than 32 amps. It also has WiFi connectivity with an app and you can see the daily, weekly and monthly usage. This is useful to see exactly how much energy you're using, and how much the EV charging is costing:

    Thanks, will look at those two. You don't have a rough idea of how much the service for JuiceBox Pro costs to have an authorized user list, it sounds like that feature is part of a monthly subscription package? The office is small and only starting with two chargers. I am the only one driving an EV now, but 2 or 3 others will switch soon.

    Might just break down and skip the lock and see if it becomes a problem. They are marked private parking, but want to avoid nearby hotel guests camping on them overnight.

    Thanks again. We decided to go cheap and go with the base JuiceBox Pro (non commercial). We figured 2 of those would save about $7,000 vs the commercial ChargePoint unit we were looking at. Someone would have to steal about 100,000 kWh of electricity before we were even negative in that situation, so just trust the private parking signs for now ;) If that fails we might just install a switch in the building to shut it off.

    In many instances you don't need a networked station, expecially with workplace applications. You could also set the circiut on a timer so it only goes on during working hours when you can monitor it. Or, allow the ocassional EV driver to plug in if they need a little juice. It really doesn't cost much to let people charge a bit and the EV community appreciates it. Unless you see abuse and then you can limit the use.

    Another good thing about getting the JuiceBox is with the app, you can see exactly when the station is being used, and how much it's costing you. Therefore, you'll see if people are abusing it.

    This is my first JuiceBox 40 Pro in an alley behind Propst and Pratt Ave:
    • located in alley to minimize ICE car parking conflicts
    • Propst is in a small shopping center with two restaurants, neighborhood grocery store, two cleaners, a pet store, music instrument shop and others
    • configured to operate between 6AM to 11PM, business hours
    • 10 miles from home, a 'free' charge of ~$0.25 pays for the drive
    So far, I've had no luck setting a timed or kWh, charge time limit, say 1 hour or ~7 kWh. This would inhibit 'charger leeches' and encourage sharing. Also, this early version has no lights indicating charging state.

    There have been some server changes that may allow users to track the charger operation. This would make it easier for others to track charge progress while shopping.

    The ideal location is centered at two or four, EV charging spots so owners can swap the J1772 between cars. In an ideal configuration, an external light visible from a building could color code or icon display: OK; charging, and; charge done. ChargePoint may have a multi-J1772 configuration that can load-share or switch between cars.

    Timer is the cheapest solution.

    Build a connector holder and lock the connector. $100 solution.

    Fancy solution: badge authentication with timer. Scan badge and set charging limit to 4-8 hrs.

  13. Thanks! Additionally, we do offer models that allow for private-only access, or the ability for both private and public access. Here's more on the models available for workplaces so you can get a better idea of other features you might want in addition to access control. Good luck with your search, and don't hesitate to send me a private message if I can help answer any additional questions you might have! - Rochelle
