Charging speed? Why is it so slow?

I've found this, a load of new 180kw chargers and I'm stuck between 40 and 50 KW, an ID buzz pulls in next to me and starts drawing 177kw, it did drop to about 122 after a bit but still, annoying born isn't charging faster when it's rated to.

My average on long trips has been a very disappointing, even shockimg, 45kW/hr when :
- the average temperature has been well over 10°C
- the chargers used have been rated variously at 120- 250kW (mainly the latter with no significant difference)
- the charging window has been almost exclusively 20-80%
- the battery protection option has been OFF
- other EVs are clearly getting top up charges of 50% (30kW+) in 15-20 minutes AT THE SAME CHARGERS

Given an advertised (even vaunted) maximum charge rate of 125kW it would seem reasonable in the UK's hospitable climate to expect a minimum of 70kW/hr and at least 100kW+ on a good day. Right now I'd settle for 60-80kW/hr because the highest I've touched briefly is 61kW/hr

On the plus side I think the Born is justifiably electric car of the year. In all other respects it's a FANTASTIC bit of kit and worth putting up with maybe 4-6 longer than expected trips a year. After all the research I did I was confident I'd like it and it has exceeded my high expectations

PS I'd recommend hand washing at least once to fully appreciate the design genius

PPS Those who are "not so experienced with public charging" should probably not be waxing lyrically about charging curves. True, there are "so many variables" but nowhere near enough to justify on average of around 45kW/hr

I got 123kW on a recent trip in ideal conditions. But the curve quickly went down after that, averaging around 72kW from 15-80%.

I've done 2 public charges so far. The first was Ionity in Sheffield and got 138kW. Then the other day Instavolt in Newbury got 80kW. Both times I prewarmed the battery for 10 mins.

How did you pre-warm the battery? On my Born there is no way to explicitly do this.

Is it a VZ / 2025 thing? In the battery menu I've got Battery Condition and can press to prewarm the battery in prep for a fast charge.

Oh nice! I'm still hoping that that feature will be added in the 3.7 software update for older models, but it seems increasingly less likely.
