There is no correct universal stock number for an EV charger distributor. The right holding for each line is a calculation the distributor runs from their own records: how fast that exact model sells, how long replenishment takes under the supplier’s written terms, and how strong a same-day promise they have chosen to make. Any other number is someone else’s business wearing your capital.
Key Takeaways
- There is no universal stock number: decide per model and variant, from your own records.
- Demand during the replenishment window, plus a buffer tied to your service promise, sets the holding.
- Watch slow lines separately — asleep capital is usually the expensive error.
- Fix a review rhythm and written trigger per line.
The Per-Line Calculation
Run the decision separately for every model and variant. Averaging a weekly portable and a monthly wallbox hides both problems.
| Input | Where it comes from | What it decides |
|---|---|---|
| Demand rate | Your own sales log for that exact model and variant — units actually invoiced, not enquiries | How many units the shelf must feed between orders |
| Lead-time exposure | The supplier’s written lead time for that line, plus freight and clearance time to your warehouse | How much demand arrives while a replenishment is still travelling |
| Service promise | The fulfilment promise you chose to make to installers — for example, same-day dispatch on core lines | How much buffer above expected demand you deliberately fund |
| Spares position | Your installed base of that model and its repair history | How many spare units and parts sit beside the sale stock, for first repairs |
In plain terms: expected sales during the replenishment window, plus a buffer sized against your service promise and your cost of a stock-out, is the holding for that line. Our guide to spare parts and the RMA process for distributors covers spares in full, and the distributor warranty and after-sales checklist covers the promises that buffer must honour.
The Slow-Line Problem
The expensive mistake is rarely running out of a fast line. It is capital asleep in slow lines: variants bought for breadth, models kept after buyers moved on, and versions that fit another market better than yours. Sleeping stock costs shelf space and attention, and a unit held too long can be superseded before it sells.
- Name the slow lines. Review movement per line, not per warehouse. A healthy total can hide five lines that have not moved.
- Separate core from catalogue. Core lines earn depth because demand is proven. Catalogue lines can be shallow, ordered in against a confirmed lead time you quote honestly.
- Decide the exit when you buy. For a new or seasonal line, write down what evidence would make you deepen it — and what would make you stop reordering.
Review Rhythm and the Reorder Trigger
Fix a review rhythm — the same day each cycle — where each line’s sales log, open orders and holding are read together and the holding rebuilt if inputs moved. The reorder trigger sits in the same record: the shelf level at which replenishment must be placed so stock arrives before the promise breaks, given the written lead time. When that lead time changes, the trigger changes with it, in writing, the same week.
Keep the record per line: demand rate used, lead time used, buffer chosen and why, trigger level, and next review date. That page turns a stock argument into a stock decision.
Stocking EVDANCE Lines
Apply the calculation per EVDANCE model. The EV-ACS4005T portable charger (9.6 kW, 16/24/32/40 A adjustable, NEMA 14-50P, IP66, 25 or 28 ft cable) and the EV-ACS3210T portable charger (about 7.7 kW, 10–32 A in six steps, NEMA 14-50P, IP66; the listing states no cable length, so confirm it in writing before quoting it) move at different rates in the same warehouse. Browse the full product range, then set each line’s holding from your own log. Supply routes and terms are on the reseller and distributor program page.
Frequently Asked Questions
Is there a standard weeks-of-cover figure distributors should hold?
No sourced standard exists for EV chargers, and this article does not offer one. Cover is the output of your demand rate, your replenishment lead time and the service promise you chose. Two distributors selling the same model can correctly hold very different stock.
Should spares be counted inside the sale-stock figure?
No. Keep them as separate lines with separate logic. Sale stock is sized from sales; spares are sized from the installed base of that model and its repair history. Mixing them makes both numbers wrong and hides a spares shortage until a failed unit arrives.
What is the first sign a line is overstocked?
Movement slowing while the holding stays flat. If invoiced units fall across successive reviews and the trigger has not been revisited, the shelf funds a demand rate that no longer exists. Cut the trigger first, then the next order.
