Many other EVs have active thermal management... Bolt does but its DC FCing isn't that fast (from what I hear). In the case of https://electricrevs.com/2018/07/17/wat ... -to-55-kw/, it may start slowing down after 55% SoC. And, I hear it's quite slow if the battery's cold, until it warms up enough.
In a race with the Bolt, 30 kwh LEAF and 40 kwh LEAF, who would win?
Winner; 30 kwh LEAF simply because of its ability to charge at full speed to 80% SOC. Test based on 5 mins plus charge time for each QC stop. There were parameters for trip length with Bolt and 40 having advantage in shorter distances due to higher range which was GREATLY mitigated if all cars started race at 50% SOC.
FYI; The 30 wins barely if the race is long enough BUT the 40 loses badly in anything over 300 miles or so.
But the main advantage of having a bigger pack is simply more charging options convenient to personal needs (which often do not follow a schedule) and the ability to charge the lower 2/3rds of the pack (something Bolt excels) which helps to slow temperature rise.
You think so?
With a sufficiently powerful DC FC. I think the Bolt would win if you only started charging the Bolt when nearly empty and cut it off at when it starts throttling down or starts becoming slower than that 30 kWh Leaf. In https://electricrevs.com/2018/07/17/wat ... -to-55-kw/, during his testing, it dropped below 54 kW charging rate once he passed 54% SoC. Was full power up until that point.
Also, if you started with a full charge on each, the Bolt would go about 2x as far as the 30 kWh Leaf on the initial charge. And, if you did multiple DC FCs in a day, I bet that 30 kWh battery would overheat and throttling might begin sooner whereas Bolt has battery thermal management.
edit: In Jeff's test, from about 54% to about 70%, he was maintaining 38+ kW charging rate. Then it sharply dropped off to about 23 to 24-ish kW.
