10%-70% vs. 0%-100%: The Great EV Charging Metric War Unfolds Over BYD and Sodium-Ion Promises
The discussion centers on rapid charging technologies, citing BYD and Geely's advancements alongside the novel promise of Sodium-ion batteries, specifically calling out a potential mismatch between advertised 450km range and the smaller 45kWh pack size noted by 'halcyoncmdr'.
People argue intensely over how charging speed should be benchmarked. 'psycotica0' and 'FrederikNJS' argue for the 10%-70% window because charging curves flatten near full capacity. Conversely, 'Steve' demands a universal 0%-100% standard for fair comparison. Additionally, 'halcyoncmdr' strongly suggests drivers must plan for mandatory 'pit stops,' shifting the focus from pure maximum range to scheduled rest. Other takes covered general EV superiority over ICE ('ethos_builder') or the necessity of 350+ mile range for seamless travel ('gramie').
The raw take is that the travel mindset must change. While some debate the 0%-100% standard, the strongest operational consensus points away from clock-watching; users treat charging stops as planned downtime. The fault line remains the marketing standard: industry jargon favors 10%-70%, but purists demand full-cycle transparency.
Key Points
Charging stops are psychological pit stops, not refueling races.
The consensus view is that travelers should plan downtime for stretching or rest, not just maximizing miles.
The 10%-70% charging metric is functionally superior.
'FrederikNJS' notes charging curves taper off aggressively near 100%, making this metric more useful for real-world use.
All charging data must be reported for a full 0%-100% cycle.
'Steve' insists this full cycle standard is required for any true, non-cherry-picked industry comparison.
Sodium-ion range figures may be misleadingly compared to older pack sizes.
'halcyoncmdr' flagged that the 450km range estimate for Sodium-ion is tied to a much smaller 45kWh pack.
Comparing EV charging kW to ICE refueling power is a valid comparison.
'sparkyshocks' claims the comparison holds because both involve massive energy transfer, and the gap is closing.
