EV charging for staff can be both either free or pay-to-use. This is up to your business and how you want to handle the costs. Either option however can be controlled by backend software to monitor access and monetise if you choose.
AC charging at the workplace is ideal because:
Cars tend to be parked for many hours enabling a full charge
AC chargers are relatively cheap and you can add to your charging fleet easily over time
Smart chargers can manage load and allocate energy to the car with the least energy
One smart AC charger with communications can manage up to 20 less advanced chargers, reducing costs
These are the key considerations for workplace charging for staff:
Cables: we recommended socketed chargers (no cable attached) because these chargers can charge every EV on the market and into the future. Chargers with attached cables limit you to one type of vehicle.
Communications: we recommend smart chargers with communications capability (modem/ethernet/WIFI) and OCPP. These chargers can be remotely supported and managed and have a wide range of features dumb chargers don't.
Monetisation: we recommend chargers with the ability to be monetised, even if you don't turn this on today. When 2% of staff vehicles are EV's it's a novelty when 50% are EVs it can become a large cost.
If there is sufficient demand you could think about putting a staff DC charger in place. The considerations for this technology are:
Cost: DC chargers are relatively expensive compared to AC chargers
Time to charge: DC chargers are for fast turnaround (30-40 minutes) charges to 80% from near empty. Most staff won't drive that far to work so an AC top-up could be sufficient.
Charging etiquette: staff will have to pop out and move their car or there will be conflict.
