Plug-Side Chat: Use Demand Fees for DC Fast Charger Pricing

I have used and showcased several of the more expensive public DC fast chargers recently, and the topic of pricing for DCFC keeps coming up. Right now, it appears the public charging providers are struggling to find a pricing structure that complies with regulations, works for a variety of EVs with a variety of charging profiles, and is sustainable from a business perspective.

I suggest that public charging providers investigate the use of “demand fees,” which would work similarly to the way utilities charge demand fees. Essentially, the EV owner would pay a rate based on their total demand (i.e., per kW of total charging capacity), which can be combined with a base per-minute or session fee. At the moment, a 10 cent per minute plus .25 cent per kW demand fee seems the most appropriate, as it would result in the following:
– A Bolt EV owner charging at 55 kW would pay: 24 cents per minute (or 26 cents/kWh)
– A Kona Electric owner charging at 70 kW would pay: 28 cents per minute (or 24 cents/kWh)
– An I-PACE owner charging at 85 kW would pay: 31 cents per minute (or 22 cents/kWh)
– An e-Tron owner charging at 150 kW would pay: 48 cents per minute (or 19 cents/kWh)

The biggest benefit to the charging providers beyond fairness is that they would be able to create a single, consistent fee structure across their entire network, and it would eliminate the need to set fees by region or charger. And that would, of course, also improve the customer experience.

The difference between the cheap and expensive unit is mostly in the USB connection & the software. The ability to control the power supply from the computer and view amperage/voltage is pretty useless unless you intend to use it for livestreaming with open broadcaster and want results to show up on the screen. For most you will want the cheaper version.
