A charger quotation is a price in a stated currency that holds for a stated window — nothing more. When the window closes, or the rate moves beyond what both sides agreed to absorb, the supplier may re-quote. The buyer’s protection is not a currency prediction: it is writing window, currency and re-quote trigger into the order before money moves.
Key Takeaways
- A quote is a price, a currency and a validity window; if the window is not written down, ask for it.
- Currency movement reaches the contract because factory costs and export quotes sit in different currencies.
- Choose deliberately who carries a move: fixed window, fix-at-deposit, a shared band, or paying in the supplier’s currency.
- A specification change re-opens the price at any point; lock the spec first.
What “Price Validity” on a Quote Actually Means
The validity window is how long the supplier will honour the quoted price for an order on the quoted specification. Three details decide what that promise is worth:
- When the clock starts. Usually the quote date — confirm it; a quote sat on for a week has less life than you think.
- What stops the clock. Some suppliers hold the price once a deposit lands; others only until the window expires. Get the rule in writing.
- What voids it. A change to model, specification, branding or quantity is a new quote, not an amendment.
Validity exists because the supplier’s costs move — see our breakdown of what drives the unit cost of an OEM EV charger for the components behind the price.

Why Exchange Rates Reach Into the Contract
An export quote is written in dollars or euros, while the factory’s costs — labour, components, rent — sit in its home currency. If the rate moves between quote and payment, one side’s margin absorbs it. Charger margins rarely leave room to absorb a large move silently, so it surfaces as a re-quote, a shorter window or a currency clause.
Nobody can forecast the rate. Decide in advance who carries which part of a move:
| Clause option | How it works | What it trades |
|---|---|---|
| Fixed price, fixed window | The quoted price holds until the window closes; after that, a fresh quote | Simple, but slow decisions cost the price |
| Price fixed at deposit | The price locks when the deposit is received, whatever the window says | Rewards fast commitment; needs the rule written on the quote |
| Shared-movement band | Price holds while the rate stays inside an agreed band; outside it, the difference is shared or re-quoted | Both sides carry part of a large move; the band has to be defined precisely |
| Quote in the supplier’s currency | The buyer pays in the factory’s home currency and carries the movement | A cleaner factory price in exchange for the buyer’s own currency risk |
Treat such wording as an example to negotiate with your supplier and advisers — not a market norm.
Before You Rely on a Quoted Price
- Confirm the quote’s currency matches what you will actually pay in.
- Confirm the validity window and what stops it — deposit, signed order, or the date alone.
- Ask what happens if the rate moves sharply before the balance falls due — get the answer on the document.
- Lock the specification; a change re-opens the price even inside the window.
- Align the window with your own approval process; a price you cannot accept in time is not a price.

Frequently Asked Questions
How long is a charger quote usually valid?
It varies by supplier and by how fast its component costs move; no general figure is safe. The window on your quote is the only real one; if none is printed, ask.
Can a supplier raise the price after we pay a deposit?
It depends on the written terms — why the fixing rule belongs on the quote. A deposit recorded as fixing the price is a different position from one paid against an expired quote.
Should we pay in dollars or in the supplier’s currency?
Either can be right. Paying in your own currency pushes the movement risk to the supplier, who prices it into validity and bands; paying in theirs can sharpen the price but leaves the movement with you. Decide with your finance adviser.
