Current obstacles
- Grid capacity for megawatt chargingMegawatt chargers need heavy grid connections or on-site batteries, which makes stations costly.
Physics limits
- Heat grows with current squaredResistive heat is current squared times resistance: doubling charging current quadruples heat in cells and cables. Megawatt charging needs liquid-cooled cables and very low-resistance cells.
- Lithium plating caps charge speedCharged too fast, especially cold or nearly full, lithium deposits as metal on the anode instead of entering it. That ages cells and can cause shorts, so charge rates taper.
- LFP stores less per kilogramLFP cells hold roughly 160–200 Wh/kg versus about 250–300 for nickel-rich cells, so long range needs a heavier pack.
How it works
1,000 volts
Higher voltage, less current
Power is voltage times current. At 1,000 V, 1 MW needs 1,000 A; at 400 V it would need 2,500 A, far beyond practical cables.
Battery
Fast-charging Blade cells
Long, flat LFP 'Blade' cells with low internal resistance take charge at up to 10C, a full charge in about six minutes, without overheating.
Chargers
Megawatt stations
BYD's own 1,000 kW chargers, some with on-site batteries to cushion the grid, add about 400 km of range in five minutes.
