Home charger
Which home charger suits the BYD Seal U?
The BYD Seal U charges at home at up to 11 kW three-phase. A 11 kW (3 phases, 16 A) charger is enough: it charges from 20 to 80% in about 4 h 15 min. A 22 kW charger does not make it faster.

- Fast charging (DC), max.
- 115 kW
The Design version has an 87 kWh battery and 140 kW DC; both charge at 11 kW three-phase.
For ERE the charger matters, not the car: home charging only earns ERE with a MID meter built into the charger. Do the charger check

Bidirectional charging
Can the BYD Seal U supply power back?
V2L according to BYD: the car works as a mobile power bank for household devices. BYD does not state the power or the adapter. No V2H or V2G offer is known.

Earning ERE with your BYD Seal U
For every kWh you charge at home you can have emission reduction units (ERE) registered and sold, through an ERE provider. Public charging does not count for you.
A charger with a built-in MID meter
Since 1 January 2026, only a MID meter built into the charger itself counts for private users. A separate MID meter in the meter cupboard, or only a smart meter, is not enough. Of the 110 charger models we researched, 53 have a built-in MID meter.
An ERE provider
The provider books your charging sessions with the NEa and sells the EREs. Commissions range from 10% to 28%; above we use the median of 20%.
Compare ERE providersCheaper at home and on the road
With a dynamic contract and smart charging you pay the least per kWh at home; on the road a suitable charging card makes a difference.
