The Hills has among the highest rates of electric vehicle ownership in Sydney, and Kellyville is now well past the point where a household's second car is electric too. That creates a situation almost nothing written about EV batteries accounts for: two vehicles and one charger.
Sharing a charger is usually good for both batteries
When a household has one wallbox and two electric cars, charging becomes a rotation. Each vehicle gets plugged in every second or third night rather than every night, and each therefore spends less time sitting at a high state of charge.
That is, unexpectedly, kind to both packs. A cell held near full ages faster than one held mid-range, permanently — so a vehicle that spends most of its life somewhere between 40% and 80% is ageing more slowly than one topped up to 100% every single night.
The other consequence is that neither vehicle ever needs a fast charge, because there is always a full one available for the longer trip. Households with two EVs typically use DC fast charging less than households with one, and DC charging is the thing that generates heat and accelerates capacity loss.
What to ask when buying from a two-EV household
It is a genuinely useful question: "Was this the main car or the second one?"
The main vehicle will have the kilometres and the deeper daily cycles. The second one will often have low kilometres and — because it sat plugged in less — may be in better condition than its age implies rather than worse.
That runs against the usual instinct, which is to assume a second car has been neglected.
The rest of the Hills picture
Garaging is close to universal on this housing stock, and rooftop solar is common, which means a lot of daytime AC charging at modest current — the gentlest charging profile there is.
Against that, commutes from here are long, typically to the city, North Sydney or Macquarie Park, or a drive to the Metro and a long park. Real distance means real cycling, and the odometer on a Hills commuter understates the work.
