EV Charging and Infrastructure
A charger’s rating is a ceiling, not a promise. A 350 kW cabinet rarely delivers 350 kW for more than a few minutes, because the battery tapers its own current to avoid damage and because cabinets share power between stalls. The gap between the advertised number and the delivered one is the running theme of this section.
Around that sit the questions that decide whether a network is usable at all: reliability, payment, connector standards, and whether the grid connection behind the forecourt can supply what the plugs promise.
Battery Swap vs Flash Charging: the Peak-Week Test
Over China’s busiest travel week, Nio ran 1.19 million battery swaps and BYD 1.22 million flash charges – a dead heat that turns the viral ‘3x more efficient’ claim into an artefact of network size.
China’s Holiday EV Charging Hit a Record. So Did the Waits
China’s expressway EV charging hit 163 million kWh over the National Day holiday, up 51% year on year, with a record 28 million kWh on day one — and seven-hour waits at the worst service areas.
Why Fast EV Chargers Now Have Batteries Inside
A battery-buffered charger delivers far more power than its grid connection supplies – FreeWire’s Boost 200 does 200 kW on a 27 kW feed. Here’s how, why, and where it stops working.
The BrightVolt Take: The 750kW Charger No Car Can Use
EVgo just previewed a 750kW fast charger for 2027. The fastest EV sold in America peaks at 600kW, and most top out at 350 or less. The number on the pylon has left the cars behind.
The BrightVolt Take: Geely’s Nio Deal Won’t Fix Car Swapping
Geely is buying 30% of Nio’s battery-swap arm at a $2.2bn valuation. It looks like the standardisation breakthrough swapping needed. It is two loss-makers consolidating to survive.
Electric Trucks Solved Range. Charging Is the New Wall.
At IAA Transportation 2026, Europe’s electric trucks converged on 600-720 km – about one legal driving day. The race has moved to megawatt charging that refills in the mandatory 45-minute break.
BYD’s 9-Minute EV Charge Runs on a Battery, Not the Grid
BYD’s Denza N8L charges its 130 kWh pack to 97% in nine minutes — about 900 kW into one car. But the megawatt charger draws only 600 kW from the grid and makes up the rest from a 1.5 MWh on-site battery.
Lithium Plating: Why Fast Charging Degrades Batteries
Charge a battery too fast or too cold and lithium plates as metal on the anode instead of storing charge — stripping capacity and, at worst, growing dendrites that short the cell.
What C-Rate Tells You About How Fast an EV Charges
A battery’s C-rate is charge speed relative to its capacity: 1C fills in an hour, 10C in six minutes. BYD hit 10C in 2025. But no car holds its peak, which is why the charger is slower.
