OCPP and EV Charger Vendor Lock-In in Malaysia: What Building Owners Should Ask Before Signing
Short answer: OCPP is an open language that lets an EV charger talk to any management software that also speaks it. If your chargers are OCPP-compliant and your contract says you own the chargers and can have them unlocked from the current backend, you can change operator without ripping units off the wall. If they are not, you are tied to one supplier for billing, pricing, firmware and support for the life of the hardware.
What OCPP actually is
OCPP stands for Open Charge Point Protocol. It is an open communication standard, maintained by the Open Charge Alliance, between a charge point and a central management system. The management system is what handles user authentication (RFID card or app), session start and stop, pricing, billing, remote diagnostics and load management.
Two versions matter in practice. OCPP 1.6J is still the most widely deployed in Malaysia. OCPP 2.0.1 adds better security, smart-charging and device-management features. Either is far better than a closed, vendor-only protocol.
The point for a building owner is simple: the charger and the software behind it are two separate purchases, even when one company sells you both. OCPP is what keeps them separable.
Locked in versus open: what changes for you
Decision | Closed / vendor-only setup | OCPP-compliant setup |
Changing operator | Hardware usually has to be replaced | Charger is re-pointed to a new backend |
Setting your tariff | Whatever the operator's app allows | You set it in the management system you chose |
Billing data | Held by the operator | Exportable session data for your own accounts |
Adding more bays later | Must buy the same brand | Any OCPP charger can join the same system |
If the supplier closes down | Units can become unmanaged | Connect to another OCPP backend |
Load management | Only within that brand | Across mixed brands on one system |
The second column is not hypothetical. Charger makers and charging software companies have gone out of business overseas, leaving owners with working hardware and no backend. OCPP hardware in that situation can be pointed at another management system; closed hardware often cannot.
What people actually ask
These are the questions that come up again and again in Malaysian EV discussions and in committee meetings, paraphrased from public threads and from Google's People also ask results for OCPP and condo charging:
“What happens if the charging company closes down?” — raised in public discussion of charger makers going bust (Pionix / LF Energy community post).
“Can I switch provider without changing the hardware?” — the core question OCPP exists to answer.
“Who sets the price per kWh, us or them?” — a recurring JMB question on Lowyat Forum threads about condo charger installs.
“Is OCPP 1.6 enough or do we need 2.0.1?” — a standard People also ask item on OCPP searches.
“Do we get the session data?” — asked whenever a management committee has to reconcile electricity bills against charging income.
None of these are really technical questions. They are contract questions with a technical answer underneath.
Five things to put in writing before you sign
1. State the OCPP version and that it is certified, not “compatible”.
“OCPP-ready” and “OCPP-compatible” mean nothing on their own. Ask for the version (1.6J or 2.0.1) and for evidence of Open Charge Alliance certification for that exact model.
2. Write down who owns the hardware.
In a zero-upfront or revenue-share arrangement the operator often owns the units. That can be the right deal — but then say in the contract what happens to the chargers at the end of the term, and at what price you can buy them.
3. Include a backend-release clause.
A charger can be OCPP-compliant and still be administratively locked to one backend. The clause you want says that on termination, and within a stated number of working days, the supplier will release the charge points so they can be connected to a management system of your choosing.
4. Require session data export.
Monthly CSV or API access to session records: date, bay, duration, kWh, amount charged. Without it the committee cannot reconcile charging income against the building's electricity bill.
5. Separate the hardware warranty from the software subscription.
If the software subscription lapses, the warranty on the physical unit should not lapse with it.
Where this sits alongside the rules
OCPP is a commercial and technical choice, not a regulatory one. It does not replace anything Suruhanjaya Tenaga requires. If your building will charge the public, or bill users in certain arrangements, licensing rules still apply, and the installation itself still has to be done by a registered contractor with the correct TNB and ST paperwork.
Does your building need an EVCS licence? covers the licensing side, and EV charger installation requirements in Malaysia covers the ST and TNB paperwork your installer must handle.
If you are still choosing between an outright purchase and a revenue-share arrangement, read Zero-investment EV charging for condos first — the lock-in question matters most in exactly that model.
What this means by building type
Condominiums (JMB / MC). You are committing the owners to a multi-year arrangement that is hard to reverse at an AGM. The backend-release clause is the single most valuable line in the contract. See our condo and JMB page for how the approval process fits around it.
Hotels and malls. Your tariff is a commercial lever — free for guests, paid for walk-ins, validated with a receipt. You cannot run those rules if the pricing lives in somebody else's app. See EV charging for malls and hotels.
Offices and factories. Here load management is the reason to care. One OCPP system can balance mixed-brand chargers against your maximum demand; two closed systems cannot talk to each other at all.
Fleets and depots. Scheduling overnight charging across a depot needs one system with visibility of every unit. Lock-in here means you can never add a cheaper or faster charger later.
Frequently asked questions
Is OCPP a legal requirement in Malaysia?
No. There is no rule obliging a building to use OCPP chargers. It is a commercial protection you negotiate for yourself, separate from the ST and TNB requirements that do apply to the installation.
Is OCPP 1.6J good enough, or should we insist on 2.0.1?
For most Malaysian condos, offices and hotels, certified 1.6J is sufficient today and is what most installed units use. 2.0.1 is worth asking for on larger or newer projects, mainly for improved security and smart-charging features. The bigger risk is a charger with no certification at all.
If our chargers are OCPP, can we switch operator tomorrow?
Not automatically. The protocol makes it technically possible; the contract makes it practically possible. Without a release clause the current supplier can simply decline to unlock the units.
We took a zero-upfront deal. Have we already lost the option?
Not necessarily. Many revenue-share agreements have renewal points and buyout provisions. Read the termination and ownership clauses before the next renewal date rather than after it.
Does OCPP affect how fast our chargers charge?
No. Charging speed is set by the charger's rated output, the car's onboard charger and your building's supply. OCPP governs communication and management, not power.
Can we mix brands of charger on one system?
Yes, if each one is OCPP-certified and your management system supports them. That is the main day-to-day benefit: you can add bays over several years without being tied to one price list.
Before your next committee meeting
Take the five clauses above into the meeting and ask each bidder to answer them in writing. A supplier that is comfortable with open standards will answer in a paragraph. One that is not will talk about something else.
