EV Charger OEM, ODM and White Label: Which Route Fits Your Brand?
Putting your name on a charger changes more than the logo. It changes who answers for compliance. Use this guide to choose a route, decide which changes need new tests and set up your first order.
By HG Power. Published 6 November 2026. Technical review: Marvin Zhou.
Most OEM talks start with the logo and the minimum order. The harder question comes later: when a customer, an inspector or a bank asks who made this charger, whose name is on the paperwork?
That answer decides how much work your brand really takes on. We wrote this guide for distributors, installers and energy companies that want a charger under their own name. It covers what each route means, what EU rules and test marks ask of a brand owner, and which changes force new testing.
What is the difference between OEM, ODM and white label EV chargers?
The difference between OEM, ODM and white label EV chargers is who owns the design. White label puts your brand on an existing charger. ODM adapts the factory’s platform to your requirements. OEM builds to a design you own. Each step gives you more control, but costs more and takes longer.
| Route | Who owns the design | What you change | Your compliance work | Best for |
|---|---|---|---|---|
| White label | Factory | Logo, label, packaging, manual | Lowest, but your name creates duties | Testing a market |
| ODM | Factory owns the platform; contract sets who owns your changes | Enclosure, screen, software, options | Medium, because changes may need tests | Building a real brand |
| OEM | You | Almost everything | Highest, because you keep the full technical file yourself | Brands with engineers and volume |
Be careful with the words. Suppliers use them differently, and some call every rebrand “OEM”. So ask one plain question: “Who owns the design, the tooling and the test reports?” The answer tells you which route you are really buying.
Hardware white label or software white label?
Hardware white label and software white label are different purchases. Hardware white label is a physical charger under your brand. Software white label is a charging app and management platform under your brand. You can buy either alone, but they must work together, so test the exact pairing first.
When we searched “white label ev charger” in November 2026, most top results were software platforms, not hardware. So check what a supplier means before you compare prices.
The link between the two is usually OCPP. If you run your own platform, ask for a test with your backend before you order. Our OCPP 2.0.1 vs 1.6 guide lists what to ask.
Who is the manufacturer when your brand is on the charger?
In the EU, the company whose brand is on the charger is usually treated as the manufacturer, even if a factory in China built it. A supply contract can share the technical work. The EU rules still look at whose name is on the product when it reaches the market.
Article 10 of the Low Voltage Directive says an importer or distributor is considered a manufacturer when it places equipment on the market under its name or trade mark. The EU’s Blue Guide says the same applies to a company that labels ready-made products and sells them under its own name.
Other marks work differently, and rules outside the EU differ again. This table shows what to ask for in each case.
| Item | What a brand owner needs to know | What to ask your factory for |
|---|---|---|
| EU CE marking | Your name can make you the manufacturer | Access to the technical file, test reports and the declaration content |
| EU radio rules | Regulation (EU) 2022/30 has applied to certain radio equipment since August 2025. It will be repealed from 11 December 2027, when the main Cyber Resilience Act duties start | How the Wi-Fi or 4G version was assessed, and the plan for 2027 |
| UL Mark | Multiple Listing lets identical certified products carry different brand names | The original file number and permission to list |
| ETL Mark | Intertek says ETL certification supports private label programs | The listing holder and how your brand can be added |
| OCPP certificate | OCA issues White Label Certificates for re-branded products | The original certificate, its date and written consent |
The OCA rule is strict and worth reading. The product must be the same inside, in both hardware and firmware version. The original vendor must consent, both vendors must confirm the products are technically identical, and the original certificate must not be older than 12 months. A different housing or user interface is allowed. The original product must already hold a full OCPP certificate, so ask whether your exact model has one.
A certificate in your supplier’s name proves that one model passed one assessment. It does not prove your version matches it, and it does not show who holds the file. Our certifications page shows what we hold. Ask for the documents for your exact model, and check them with your test lab or lawyer. This guide is not legal advice.
The Re-Test Line: which changes need new testing?
Sort every requested change into three tiers: label, configure or re-test. Label changes touch only the outside identity. Configure changes use options the model already has. Re-test changes affect safety, heat, electrical performance or radio, so ask your test lab before you approve them or commit to a launch date.

OCPP, screen page

When a change could fall into two tiers, treat it as the higher one until your test lab says otherwise.
| Requested change | Usual tier | Why |
|---|---|---|
| Logo, carton, manual | Label | No electrical change, but the documents must match the brand |
| Nameplate | Label | It carries your name, so it must match the file and any listing rules |
| Colour | Label | Becomes a re-test item if the coating or material changes |
| Screen start page and language | Configure | A new firmware build can affect an OCPP certificate, so ask for the version |
| Listed connector | Configure | Ask for the report that covers that exact variant |
| Listed OCPP version | Configure | The firmware differs, so ask which version was tested |
| Wi-Fi or 4G option | Configure or re-test | Radio parts may make EU radio rules apply |
| Payment reader or RFID type | Configure or re-test | May add radio rules and separate payment approvals |
| Cable length or cable type | Re-test | Length and type can change heat and voltage drop |
| New enclosure or vents | Re-test | Can change cooling and the IP rating |
| Power module, relay or protection parts | Re-test | Directly affects the safety assessment |
| Control firmware | Re-test | Can change charging behaviour and any OCPP certificate |
What can HG Power customize?
HG Power offers OEM and ODM work on a range of more than 200 models, from AC wallboxes to megawatt DC systems. Listed options cover connector, OCPP version, network and access method. Branding and other custom work are agreed directly with our sales team, because they depend on the model and the change.
Start with what the model already offers. These options come from our 2026 product selection manual, and they differ by model.
| Option | AC chargers | DC chargers |
|---|---|---|
| Output interface | Type 1, Type 2, GB/T, NACS | CCS1, NACS, CCS2, CHAdeMO, GB/T |
| Backend protocol | OCPP 1.6 or 2.0.1 (optional) | OCPP 1.6 or 2.0.1 (optional) |
| Network | Ethernet; 3G, 4G and Wi-Fi on listed models | Ethernet, 3G, 4G, Wi-Fi (optional) |
| User access | QR code, RFID card, password | QR code, password; card on listed models |
| Screen | 4.3 or 7 inches, by model | 4.3, 7 or 12.1 inches, by model; 43-inch advertising model |
A market version is more than a different plug. Our 2025 overseas product list shows a 240 kW dual-gun charger at 250 A with CCS2 and 200 A with CHAdeMO. The ETL version for the US is listed at 300 A with 480 V input. So the same cabinet can carry different ratings, and you should check the rating and report for your exact version.
Behind this sits a plant of 30,000 m², more than 100 R&D engineers and more than 100 patents, with annual capacity above 100,000 units. HG Power was founded in 2016 and has more than 200 employees. These figures show we can do the work. They do not show that one change is approved for one market, so confirm each change in writing.
How much does custom work add per unit?
Divide the one-off cost by the units you will really sell. A US$10,000 customization adds US$200 per unit on 50 units but only US$10 on 1,000 units. So the right route depends on your honest first-year volume, not your best forecast, and on how much of the cost is repeatable.
| One-off cost (example) | 50 units | 200 units | 1,000 units |
|---|---|---|---|
| US$10,000 | US$200 each | US$50 each | US$10 each |
| US$100,000 | US$2,000 each | US$500 each | US$100 each |
These are worked examples, not HG Power prices. For a market view, one Chinese supplier’s guide gives US$3,000–15,000 and 6–12 weeks for ODM, and US$50,000–200,000 and 18–36 months for full OEM. In November 2026, published minimums we reviewed from Chinese suppliers ran from about 50 to 500 AC units per order. Treat these as one-off examples, because scope changes the number.
Stock units start from one unit, so you can test before you commit. Custom minimums and samples are agreed with our sales team.
Which route should you choose?
Most new brands should test one stock unit, launch with white label, then move to ODM when sales justify it. Choose OEM only if you have your own engineers, a clear reason a standard platform cannot work, and enough volume to carry the design, tooling and testing costs alone.
| Your situation | Start with | Why |
|---|---|---|
| New to chargers, testing one market | Stock unit, then white label | Lowest risk and quickest feedback |
| Selling steadily, losing deals on price | ODM | You need something competitors cannot buy |
| Own platform and app already | White label or ODM with OCPP testing | Your value sits in software |
| Tender needs a set specification | Configured model first | Listed options may already meet it |
| Own hardware and firmware engineers | OEM | You can review and own the design |
White label has one clear weakness: a competitor can buy the same charger. So plan what will make your offer different, such as service, software, local stock or installation. If you plan to resell without your own brand, see our distributor program instead.
How do you run an EV charger OEM project?
Run it in six steps: set the market, pick a base model, sort each change with the Re-Test Line, order a test unit, agree terms in writing, then start production. The order matters, because changes found after production starts cost far more than changes found on paper.
- Set the market. List your country, vehicles, supply voltage, connector and required marks.
- Pick a base model. Start from our AC chargers or DC chargers.
- Sort your changes. Use the Re-Test Line, and ask your test lab about anything above the line.
- Test a unit. Check your backend, your payment flow and your installation steps.
- Agree the terms. Write down ownership, documents and timing.
- Start production. Our standard lead time is 30–35 days after full payment, and custom timing is agreed with our sales team.
Check the factory as well. Our manufacturer verification guide shows how to check any Chinese supplier, including us.
What should an OEM contract cover?
Cover seven things: tooling, test reports, firmware, component changes, exclusivity, warranty and exit. Write down who owns each item and what happens if you change factories. These terms decide how hard it is to leave later, and they matter more than the first unit price.
| Term | Question to settle | What can go wrong |
|---|---|---|
| Tooling | Who owns the molds you paid for? | You cannot move them later |
| Test reports | In whose name, and do you receive a full copy? | You cannot answer an inspector |
| Firmware | Who may update units in the field? | A change breaks your backend |
| Component changes | How much notice do you get? | A part changes and your file no longer matches |
| Exclusivity | Which design, which market and for how long? | A competitor sells your version |
| Warranty | Who handles claims on units under your brand? Our standard term is 2 years | Your customer calls you, not the factory |
| Exit | What can you take if you leave? | You restart from zero |
Five questions buyers ask
What is the minimum order for an EV charger OEM project?
At HG Power, stock units start from one unit, so you can test a model first. Minimums for custom configurations and samples are agreed directly with our sales team, because they depend on the changes you need and the model you choose.
Can I sell HG Power chargers under my own brand?
Branding and custom configurations are agreed directly with our sales team. Tell us the model, the market and what you want to change. Remember that your name on the charger can bring legal duties in your market.
Will other companies sell the same charger?
On a white label product, usually yes, because the design stays with the factory. If exclusivity matters, ask for it early and write down the design, market and period. Differences in service, software and local stock also protect your offer.
Do I need new certificates for my brand?
Often you need some new paperwork, even if the hardware is identical. The EU treats you as the manufacturer under your own name, and UL and OCA have their own routes for re-branded products. Check each market with your test lab early.
Can you connect the charger to my own platform?
OCPP 1.6 and 2.0.1 are optional on our listed models. Tell us your platform before you order, and test it on a stock unit first. Compatibility should be proven on your backend, not assumed from a data sheet.
Send us your brand plan
Tell us your market, target model, the changes you want and your realistic first-year volume. We will sort the changes with you and confirm what can be done. Request an OEM discussion, or start with our distributor program.
