Why EV Infrastructure May Need an Independent Decision Layer
What independent technology reviews, information asymmetry, and the economics of “credence goods” reveal about how electric vehicle (EV) charging decisions can be structured
As EV charging infrastructure moves from an emerging technology discussion toward actual commercial deployment, one question becomes increasingly important:
Who helps a Property Owner determine what charging infrastructure actually makes sense for the property before a deployment solution is selected?
Research into consumer technology reviews, information economics, and professional advisory services points to a common mechanism: when buyers cannot easily evaluate a complex product or service themselves, credible independent information can reduce uncertainty and improve the quality of the decision.
This is the principle behind ZEEE Green's developing role as an independent decision layer for EV infrastructure.
The concept does not require Providers to be viewed as the problem. Providers remain essential to the ecosystem because they bring the technology, engineering expertise, deployment capability, and operating models required to build and operate charging infrastructure.
The question is different:
Should the decision about what a property needs be made separately from the decision about what solution will ultimately be deployed?
There is a substantial body of economic research suggesting that, in certain markets, there is value in doing exactly that.
The technology-review example
Consider how consumers purchase smartphones and laptops.
When Samsung introduces a new Galaxy device, Samsung can explain the product's specifications, capabilities, improvements, and intended benefits.
That information is valuable because the manufacturer knows its product better than anyone.
Yet consumers frequently seek information outside the manufacturer's own channels.
They read reviews. They watch independent testing. They compare products. They look for people who have evaluated the device and can explain not only what the product does, but where it performs well, where it has limitations, and whether it makes sense for a particular use case.
The distinction is important.
The manufacturer's role is to explain its product.
The independent reviewer's role is to evaluate it from the buyer's perspective.
Research supports the importance of this information intermediary function.
A 2024 meta-analysis by Keda Qiu and Liyi Zhang, covering 156 studies, 214 effect sizes and 69,006 observations, found that online reviews significantly affect purchase intention. Review valence, meaning whether a review is positive or negative, had the strongest effect of the factors examined (Data and Information Management, 2024).
The important point is not simply that reviews can influence sales.
It is why buyers look for them.
They are trying to reduce uncertainty.
The problem becomes larger with EV infrastructure
A smartphone purchase and an EV charging deployment are obviously not equivalent.
The financial scale, technical requirements, number of stakeholders, and consequences of a poor decision can be significantly greater for infrastructure.
For a Property Owner, an EV charging decision may involve:
- Available parking
- Electrical capacity
- Expected charging demand
- AC (alternating current) versus DC (direct current) deployment
- Number and configuration of charging points
- Capital expenditure
- Operating costs
- Software and maintenance
- Revenue assumptions
- Deployment models
- Compliance requirements
- Long-term property strategy
This means the question isn't simply:
“Which charger should we install?”
The more fundamental question is:
“What charging infrastructure makes sense for this property?”
That distinction changes the role of information.
The Property Owner does not necessarily need more product information.
The Property Owner needs decision information.
The economic theory underneath the phenomenon
The idea of an independent decision layer is not based solely on consumer behavior.
There is an established economic theory behind it.
In 1970, economist George Akerlof wrote The Market for “Lemons,” (Quarterly Journal of Economics, 1970), examining what happens when buyers and sellers possess different levels of information about the quality of what is being sold.
The seller knows more.
The buyer knows less.
This is known as information asymmetry.
Akerlof's framework demonstrated how information asymmetry can distort markets because buyers have difficulty distinguishing high-quality offerings from lower-quality ones. When buyers cannot reliably assess quality, uncertainty affects their willingness to transact.
One mechanism identified in the broader literature for addressing this problem is independent inspection or certification.
A familiar example is a used-car purchase.
The seller knows the vehicle.
The buyer does not know the vehicle in the same way.
An independent mechanic can inspect the vehicle before the buyer commits.
The mechanic does not sell the car.
The mechanic provides value by helping the buyer understand what they are actually buying.
The same basic logic can apply to technically complex infrastructure decisions.
When the buyer cannot even determine whether the solution was appropriate
The economic concept of credence goods takes the problem one step further.
Darby and Karni introduced the concept in 1973 (Journal of Law and Economics, 1973), and later research by Dulleck and Kerschbamer developed the theory further (Journal of Economic Literature, 2006).
A credence good is a service where the customer may have difficulty determining whether the service was necessary, whether the appropriate amount was provided, or whether the quality of the work was appropriate, even after the service has been delivered. Technical installation work is among the types of services that can exhibit these characteristics.
This is particularly relevant to infrastructure.
Imagine a Property Owner receives an EV charging deployment.
The system works.
But the Property Owner may still have difficulty answering:
- Was this the right size?
- Was this the right configuration?
- Did we need this level of charging capacity?
- Would another deployment model have produced a better commercial outcome?
- Were the assumptions used to justify the deployment reasonable?
Again, this does not imply that a Provider has acted improperly.
It identifies a structural information problem.
The buyer is making a technical decision in an area where the buyer may not possess the expertise required to independently verify every element of the recommendation.
The load-bearing finding: separate diagnosis from treatment
This is where the research becomes particularly relevant to EV infrastructure.
The credence-goods literature identifies separating diagnosis from treatment as an important mechanism for addressing this class of information problem.
In simple terms:
First determine what is needed. Then determine who should provide it.
A medical analogy is straightforward.
Diagnosis determines the condition.
Treatment addresses the condition.
The same principle exists in other professional services.
An independent mechanic can determine what a vehicle requires before a repair is authorized.
An architect or engineer can establish design requirements before materials and contractors are selected.
For EV infrastructure, the equivalent could be:
Diagnosis. What does this property require?
Treatment. What solution should be deployed to satisfy those requirements?
The distinction is important because the first question is about the need, while the second is about the solution.
ZEEE Green's existing assessment-before-Provider-selection structure follows this logic.
ZEEE Green's site screening is intended to establish the property's conditions and requirements before Provider proposals are evaluated. The Provider subsequently brings its own technology and deployment capability into the process.
In that sense, the separation is not merely a marketing concept.
It is a form of market design that has a basis in the economics of information asymmetry and credence goods.
Why this matters to Property Owners
For a Property Owner, the benefit of this approach is not simply having another party involved in the transaction.
The potential benefit is clarity before commitment.
Instead of starting with:
“Which Provider should we talk to?”
the process can start with:
“What are the characteristics, opportunities, constraints, and requirements of this property?”
That can then lead to:
- Property assessment
- Requirements
- Viable deployment options
- Provider evaluation
- Commercial comparison
- Property Owner decision
- Deployment
This sequencing creates a clearer separation between determining the need and selecting the solution.
Why this matters to Providers too
The independent layer does not have to be positioned as something that works against Providers.
In fact, it can potentially make the Provider's role clearer.
A Provider can focus on what it does best:
Technology. Engineering. Deployment. Operations. Charging services.
The independent assessment can establish the context in which those capabilities are being evaluated.
The result is not:
ZEEE Green versus Providers.
It is:
Property Owner + Independent Decision Layer + Provider
Each has a different role.
The Provider brings the solution.
The Property Owner makes the commercial decision.
The independent layer helps establish the basis on which that decision is made.
The B2B buying process adds another dimension
There is another reason this may matter as the EV infrastructure market develops.
B2B (business to business) buyers increasingly conduct substantial research before engaging suppliers.
Gartner's research on the B2B buying journey finds that buyers spend about 17% of their buying time meeting potential suppliers, and about 27% researching independently online (Gartner, The B2B Buying Journey).
When several suppliers are being considered, Gartner finds that a single supplier may receive only 5 to 6% of the buyer's total buying time.
Gartner also reports that 77% of B2B buyers describe their latest purchase as very complex or difficult, and that a typical buying group for a complex purchase involves six to 10 decision makers.
These numbers should be treated carefully.
These are general B2B figures from Gartner. They are not Philippine EV charging statistics, and should not be read as such.
But the underlying behavior is relevant.
A significant infrastructure decision can involve ownership, management, finance, engineering, facilities, operations, and procurement.
Each participant may independently research the decision.
This creates a potential opportunity for an organization that can provide credible information before the Provider selection stage.
But independence itself is not enough
There is an important caveat.
An organization cannot simply say:
“We are independent.”
and expect the market to accept the claim.
Trust in a certification or third-party assessment depends on the credibility of the organization providing it. A self-declared independence claim can therefore be weaker than independently demonstrated independence.
This is particularly important for ZEEE Green.
If independence is going to be part of the business model, it has to be demonstrated through how the business operates, not simply through how it describes itself.
That means:
- A defined assessment methodology
- Separation between assessment and deployment
- Provider-neutral evaluation
- Structured comparison of suitable solutions
- Property Owner decision authority
- Written disclosure of Provider-related compensation
- Consistent documentation of the decision process
ZEEE Green's existing framework incorporates several of these mechanisms. Provider-related compensation is intended to be disclosed in writing before the Property Owner makes a final Provider selection, while the Property Owner retains the decision authority.
The bigger opportunity
The Philippine EV infrastructure market does not only need more charging stations.
It also needs better decisions about:
- Where should charging infrastructure be deployed?
- What type of charging is appropriate?
- How much infrastructure is justified?
- What deployment model makes sense?
- What commercial assumptions support the project?
- Which available solutions fit the property's requirements?
Those decisions precede the charger.
And that is where ZEEE Green sees its role.
Not as a replacement for the Provider.
Not as a competing charging network.
Not as a seller of charging hardware.
But as an independent layer that helps structure the decision before deployment.
The underlying economic principle is simple:
When one party has significantly more information than another, credible independent information can create value by reducing uncertainty.
For EV infrastructure, that means there may be value in establishing what the property needs before determining what solution it should receive.
That is the role ZEEE Green is working to build.
Assess first. Understand the requirement. Evaluate the options. Then deploy.
