Check the exact car, not the badge. A model line can advertise bidirectional charging while the feature sits on one trim, in one market, or behind an adapter sold separately — and “V2H” in a brochure can mean anything from a working home-backup system to hardware that is merely ready for a future update. Four checks settle it before you sign: the spec sheet for your trim, the owner’s manual, the adapter question, and the dealer’s answer in writing.
Key Takeaways
- Verify the exact trim and market: bidirectional features vary within a single model range.
- The owner’s manual is the authority — no discharge section means no discharge feature.
- “Ready” is not “working”: adapters, matched chargers and software can all be separate.
- Get the dealer’s confirmation in writing, and price any promised update as absent.
First, Know Which Flavour You Are Checking For
The three features are different capabilities, and a car can have one without the others. Our overview of bidirectional charging: V2L, V2H and V2G explained defines each in full; in short, V2L powers devices from a socket or adapter, V2H feeds house circuits through a matched bidirectional charger, and V2G exports to the grid under a utility program. Our list of which EVs can do bidirectional charging is the starting point for what exists — this article is about verifying the specific car in front of you.
The Four Checks
| Where to check | What you are looking for | Warning sign |
|---|---|---|
| The spec sheet for your trim and market | V2L, V2H or V2G named for that trim — not just for the model range | The feature appears in launch publicity but not on your trim’s sheet |
| The owner’s manual | A discharge section: an outlet, a discharge limit setting, instructions for the adapter | No discharge section at all — the manual describes charging only |
| The boot and the price list | The discharge adapter included, or listed as a priced accessory | “Available” turns out to mean an adapter you must buy, possibly not yet on sale |
| The dealer, in writing | Confirmation the feature is enabled on cars sold here, now | “Coming by software update” with no date — treat that as not included today |
Words That Sound Alike but Are Not
- “Bidirectional ready” can mean the hardware could support discharge with the right charger or a future update. It is not the same as a working feature on delivery day.
- “V2L capable” says nothing about V2H. Powering a kettle at a campsite and powering house circuits are different systems with different equipment.
- “V2G ready” does not put you on a program. Export also needs a compatible bidirectional charger, utility approval and a scheme operating where you live — our status check on when vehicle-to-home will be available shows how patchy availability still is.
- A socket in the cabin is not automatically V2L at a useful rating. The manual’s stated output is the number that matters.
Questions to Ask Before You Sign
- Is the discharge adapter in the car, or an accessory — and what does it cost?
- For V2H: does home backup need the maker’s own bidirectional charger, and is that charger on sale in this market yet?
- Is the feature enabled on cars delivered here today, or promised by update?
- Does using discharge carry any conditions in the battery warranty wording?
And the Charger Side
Verifying the car is step one; the home side still has to match. Most wall chargers sold today, including the EVDANCE EV-ACT5006T 48A Level 2 wall charger, are one-way units for everyday charging — a bidirectional car uses its maker’s matched discharge equipment for backup power, not a standard wallbox. See the residential charging solutions page for the one-way home range that covers daily driving either way.
Frequently Asked Questions
The brochure says “bidirectional charging”. Which type does the car have?
The brochure alone cannot tell you. Ask which of V2L, V2H and V2G is fitted to your trim, and confirm it in the manual’s discharge section. Many cars offer V2L only.
Can a software update add V2H later?
Sometimes makers enable features this way, but an undated promise is not a feature. Price the car as it ships today, and get any update commitment in writing if it affects your decision.
Does a Tesla do V2H?
That depends on the model and market, and the answer changes — our dedicated check on whether a Tesla can do vehicle-to-home tracks it. Run the same four checks on any brand.
