Does the Battery Brand Help Sell an Electric Car?

Battery suppliers can become part of the buying decision. The evidence is strongest when we ask exactly what consumers were choosing—or asking to know.

Imagine two electric cars with similar prices, range, and equipment. Would knowing the battery supplier change your shortlist? Would it change how much you would pay?

Those questions matter to automakers deciding what to put in a sales brochure and to battery companies trying to become recognizable consumer brands. For suppliers, the opportunity is to understand when recognition becomes a reason to choose a car.

Consumer studies in China and Europe, together with NIQ's international brand results, help explain where battery suppliers enter the buying decision. Each provides a different view of how a component manufacturer's identity can become relevant to the person choosing a car.

In China, battery-brand trust enters the buying decision

McKinsey's 2025 China Auto Consumer Insights report found that 42% of EV respondents selected a trusted battery brand as a buying factor. For context, 60% selected range and charging time, 48% a trusted car brand, and 46% advanced battery technology. These are selected factors from a longer list, not a complete ranking. McKinsey, Exhibit 19.

Original visualization of Exhibit 19. The full survey covered 2,498 automotive consumers in 19 Chinese cities, including ICE and EV consumers; the EV subgroup size is not separately disclosed. Fieldwork: Q4 2024–Q1 2025. Percentages are reported buying factors and need not sum to 100%.

This gives battery suppliers a reason to investigate consumer branding. Their identity appears in the same buying-factor framework as the vehicle brand and product attributes.

The finding still leaves important commercial questions open. It does not identify which supplier a respondent trusts, whether that trust changed the vehicle eventually purchased, or what the buyer would sacrifice to obtain a preferred battery. A supplier could be a welcome reassurance without being decisive when price, availability, or range changes.

For an automaker, the useful next question is specific: does disclosing the supplier help a customer choose between the configurations actually available?

NIQ adds an international view of named suppliers

NIQ's 2026 Global NEV Consumer Research Report contributes a comparison of named battery suppliers across nine reporting markets and regional groups. It surveyed 10,090 NEV owners and prospective buyers aged 20–55 in 22 countries. NIQ publication and methodology.

Original visualization of NIQ's complete table. These are reported intentions, not market shares or actual purchases. Regional groupings follow the report. North America combines 450 US and 457 Canadian respondents; Japan and South Korea are also combined. Sample composition.

NIQ reports 37.1% for CATL in China, compared with 18.4% for BYD and 8.0% for LG Energy Solution. In its North American results, CATL and LG Energy Solution recorded 17.0% and 16.6%, respectively.

The commercial value of the comparison is the question it raises for local sales and marketing: which supplier names help a vehicle gain consideration in the market where it will be sold? An automaker can use these findings to choose what to investigate with its own prospective customers.

McKinsey and NIQ examine related parts of this question. The former measures battery-brand trust among buying factors; the latter reports stated intentions associated with named suppliers. Their results can inform the same strategy.

European research asks what buyers want to know

A peer-reviewed study by Popowicz and colleagues examined battery-passport information using 211 valid responses, predominantly from Germany and Austria. Of those participants, 196 owned EVs. Published in 2025, the study used a survey launched in December 2022 and recruited through EV forums. Original study.

Expected lifetime and warranty received higher overall median scores than manufacturer and supplier information. Each respondent's score multiplied interest by importance, both rated from one to six. The resulting scores describe information priorities, not purchase probabilities.

Original visualization of three selected attributes from the study's 22; values come from Popowicz et al., Figure 4. This purposive sample is not representative of European buyers. The manufacturer/supplier attribute also includes production location and date. Scores cannot be compared numerically with the percentages in the China chart.

The finding offers a useful question for sales teams: what is the buyer trying to establish by asking about the battery?

A supplier's name may be part of the answer. The customer may also want to understand expected life, warranty coverage, or what happens if a problem develops. Research should distinguish these needs before a company decides that putting a larger supplier logo in its advertising will help.

For automakers, this raises a practical question: alongside identifying the supplier, how clearly do sales materials explain expected lifetime and warranty coverage? A vehicle-choice study could examine how these details work together when a buyer compares offers.

Measure the decision a brand is supposed to change

The next useful research step is a choice experiment: vary the disclosed supplier while holding the vehicle's other attributes constant, then separately introduce changes in price, warranty, or delivery time. That would test whether the name itself affects stated choice and what trade-offs buyers are willing to make.

Observed behavior would strengthen the evidence further. Shortlist selection, test-drive requests, deposits, and completed purchases should be measured separately.

For now, an automaker can make battery information easier to use: identify the supplier accurately, explain the relevant warranty, and make clear which configuration the information describes. A battery company can investigate which associations customers attach to its name and whether those associations survive a realistic vehicle comparison.

That is the commercial question worth pursuing: when the buyer reaches the order page, what does the battery brand actually change?
