As electric mobility and energy storage scale up in India, the lithium-ion battery has become a strategic product — and its efficiency, not just its capacity, increasingly matters. The Bureau of Energy Efficiency (BEE) has brought high-energy lithium-ion traction batteries and systems into its Standards & Labelling programme as a notified category (Schedule 29). A BEE star label lets a battery's energy performance be measured and compared on a common scale.
For cell makers, pack assemblers and importers, the label is an early credibility marker in a fast-growing, quality-sensitive supply chain. This guide explains where lithium-ion batteries sit in the scheme, what the rating measures, how to register, and the documents, timeline and pitfalls to plan for.
⚖ Is BEE Star Labelling Mandatory or Voluntary?
High-energy lithium-ion batteries and systems are covered under the voluntary phase of the BEE programme (Schedule 29). As a newer, technically specialised category, labelling is optional today, but the policy focus on EVs and storage makes it a strong candidate for wider adoption — so early registration is a sensible hedge.
📌 In supply chains where buyers cannot easily verify performance claims themselves, a government-backed efficiency band is a rare, trusted signal of quality.
🏷 What the BEE Star Label Displays
The label is designed so a buyer can compare two models in seconds. Every BEE star label carries the same core information:
Star Rating (1–5)
The headline energy-efficiency band, from 1 star (least efficient) to 5 stars (most efficient) in its category.
Energy / Performance Figure
The model's measured energy, fuel or thermal-performance figure under the standard test, so buyers can compare running cost at a glance.
Make, Model & Category
Brand, model designation and equipment category the star band applies to.
BEE Licence No. & QR
The registration/licence number and a QR code allowing anyone to verify the label on the BEE portal.
🔬 What the Battery Star Rating Measures
The star band for a lithium-ion battery or system is based on its energy performance — broadly its energy efficiency, such as how much of the energy put in during charging is recovered on discharge (round-trip efficiency), measured under the defined test method. Higher efficiency means less energy wasted as heat and a higher star band. The label presents this within the battery's category.
⭐ How the 1–5 Star Rating Works
The scale runs from 1 to 5 stars and the thresholds are relative and revised periodically. For a fast-moving category like batteries, expect the bands to tighten as the technology matures, so build re-rating into the product plan.
📋 Step-by-Step: Getting the BEE Star Label
The star label is granted on a test-and-register basis. The sequence is:
- Confirm the schedule and test methodVerify the current BEE schedule, star-band table and test method that apply to your product before testing.
- Test at an accredited laboratoryHave representative samples tested for energy performance at a BEE-recognised / NABL-accredited laboratory. The test report is the basis of the star rating.
- Prepare documents and the scheme agreementCompile company, brand and product documents and sign the standard label-use agreement on non-judicial stamp paper (INR 100).
- Register and apply on the BEE portalCreate the manufacturer account and file the model application with the test report on the BEE Star Label portal (beestarlabel.com).
- BEE scrutiny and model approvalBEE reviews the application, assigns the star band, and grants permission to use the label with a registration/licence number.
- Print and display the labelApply the approved star label with the correct rating, energy value, licence number and QR on the product and packaging.
- Maintain, check-test and re-rateKeep conformity under BEE check-testing and re-rate the model when star bands are periodically revised or the model changes.
📄 Documents Required
A complete file at the outset is the biggest single lever on approval speed. You will typically need:
- Certificate of Incorporation / business registration of the manufacturer, trader or seller
- Duly signed and stamped BEE application form
- Energy-performance test report from a BEE-recognised / NABL-accredited laboratory
- Product technical specifications and datasheet
- Brand / trademark ownership or authorisation documents
- Model list with photographs and rating-plate details
- Label artwork showing the star rating, energy value, licence number and QR code
- Signed label-use agreement on non-judicial stamp paper (INR 100)
- Authorised signatory details and declarations
⏱ Timeline, Validity & Re-Rating
Allow a few weeks for testing and a relatively quick approval once a complete application is on the BEE portal. The label permission is time-bound and tied to the scheme agreement, and must be refreshed at band revisions.
💰 Why the Voluntary Label Is Still Worth It
Even though the label is not compulsory for this category today, manufacturers increasingly choose to carry it for hard commercial reasons:
- A visible shelf and e-commerce advantage — the star label is what many buyers scan for when comparing models, and marketplaces surface it in filters and specifications.
- Credible, verifiable efficiency claims — a BEE band is a government-verified number, far stronger than a self-declared “energy-saving” claim.
- Readiness for a mandatory transition — BEE routinely moves categories from voluntary to mandatory; early adopters are already compliant when that happens.
- Access to tenders and green procurement — government and institutional buyers frequently specify a minimum star rating.
- A platform for premium positioning — a high star band supports a higher price point against unrated competition.
⚠ Common Mistakes That Delay a BEE Registration
- Treating the label as cosmetic — the printed star band must match a valid, current test report; mismatches are the first thing BEE check-testing catches.
- Using an outdated star-band table — bands are revised periodically, and a model that was 5-star can drop a star at the next revision.
- Label artwork errors — wrong performance figure, missing licence number, or a non-working QR code.
- Testing at a non-recognised lab — only reports from BEE-recognised / NABL-accredited laboratories are accepted.
- Not re-rating after a design change — changing a core component can alter the measured performance and the rating.
- Treating BEE as the only requirement — lithium-ion cells and batteries also fall under applicable BIS safety requirements; BEE labelling covers energy performance and does not replace safety certification.
❓ Frequently Asked Questions
Is BEE star labelling mandatory for lithium-ion batteries?
No. High-energy lithium-ion traction batteries and systems are in the voluntary phase of the BEE Standards & Labelling programme (Schedule 29). Registration is optional but valuable in the EV and storage supply chains.
What does the battery star rating measure?
It reflects the battery/system's energy performance — broadly its energy efficiency (such as round-trip efficiency) under the standard test — mapped to a 1-to-5 star band.
Does BEE labelling replace battery safety certification?
No. Lithium-ion cells and batteries also fall under applicable BIS safety requirements. BEE labelling covers energy performance; safety certification is a separate, distinct obligation.
Who typically wants a battery star label?
Manufacturers supplying EV makers, energy-storage integrators and institutional buyers, where a verified efficiency band supports quality and procurement claims.
How long does BEE registration take?
A few weeks for testing at a recognised laboratory, then relatively quick model approval on the BEE portal once a complete application is filed.
Can multiple battery systems be registered together?
Yes. Different models and systems can be registered under one manufacturer account, each with its own star band and licence number.
