AC or DC chargers for a fleet?
For vehicles parked overnight, AC is usually enough. An 11 kW AC charger adds about 110 kWh over 10 hours, which is more than most vans use in a day.
How they compare
| AC charger | DC fast charger | |
|---|---|---|
| Typical size | 7 to 22 kW | 50 kW and up |
| Indicative cost, installed | About $5,000 each | $25,000 to $30,000 each |
| Best for | Overnight charging | Top-ups during a shift, and large trucks |
| Usual setup | One per vehicle | Shared between several vehicles |
Costs depend heavily on your site, so treat these as a guide.
How many chargers?
One AC charger per vehicle is simplest. Nobody has to move vehicles during the night, and load management can share the available power.
DC chargers are usually shared. Our calculators assume four vehicles to each DC charger. Someone then has to move vehicles between chargers overnight, unless the charger has several plugs.
What is load management?
Load management shares the available power between chargers, so your site stays under its limit. It can often avoid or delay a supply upgrade. See it at work. Check your site.
