I've been getting about the same peak rate (63 kw, but takes 5-10 mins to get up to that) in cold temps (< 40 F) on 2023 ID.4 (SK battery) at two different EA chargers and a Volta. If it's anywhere near freezing or below (like 12F today!) you are
going to get slower charging speeds. The question is how much slower? This is not spelled out on the VW website at all but mentioned in the footnotes:
"Based on charging at a 170kW or higher charger. Charging times will vary and depend on a variety of factors, including ambient temperature
, charger type, battery condition and initial state of charge, vehicle condition and others. Frequent and consecutive fast charging can permanently decrease battery capacity. Vehicles equipped with cells and modules supplied by SK On charge in about 30 min. Vehicles equipped with cells and modules supplied by LG charge in about 36 min. See Monroney Label (window sticker) for cell and module manufacturer. "
However, it's hard to find any real numbers about what to expect. Here's a few references to suggest it should go higher
than 60-65 kW:
- How Fast Does The Volkswagen ID.4 Charge? Our DC Fast Charge Test Finds Out (insideevs.com) (claims went to 120 kW in low 40s F)
- Review: VW ID.4 gives drivers what they need - heat pump, power, range in winter - without paying extra - The Globe and Mail - this reviewer only recorded a < 20% rate drop in winter
Here are the Electrify America Terms and Conditions: 2023 VWID4 Charging Plan Disclosure | Electrify America
. These specifically say "Subject to the waiting period and other restrictions described below, there is no limit on the number of eligible charging sessions or the kWh amount of charging available
in each session during the Plan.'
So, what I'm going to do is call EA next time during a slow charge session and ask them why it's not charging at a higher rate. I would directly ask them if EA limits the speed (and record it) and see what they say.
Hope we'll get some answers soon.
