Taiwan Has Started Mandatory EV Charger Inspections, With More Coming in 2028
Taiwan's mandatory inspection rules for EV chargers took effect in 2026. They sit alongside a metering verification scheme that has been running for more than three years, so chargers get checked both before and after they reach the market. One system covers safety, the other covers billing accuracy. Together, they show EV charging growing up from an emerging technology into public infrastructure.
From Voluntary Certification to Mandatory Inspection
Taiwan has been aligning with international standards since 2011 and has published 29 national standards for EV chargers. They cover electrical safety, electromagnetic compatibility, communication interoperability, cybersecurity and metrology, and six designated labs are authorized to run the tests.
The Bureau of Standards, Metrology and Inspection (BSMI) under the Ministry of Economic Affairs has rolled out inspection in stages:
- 2013: Voluntary certification starts with AC slow charging
- 2022: DC fast charging joins the voluntary scheme
- July 2026: With chargers now showing up in people's homes, home chargers up to 30 kW become subject to mandatory inspection
- 2028: Mandatory inspection expands to chargers up to 750 kW
In practice, a charger has to be certified against the inspection standards before it can enter the market, and BSMI follows up with post-market checks.
Every kWh Counts: How Charging Is Metered
Safety is only half the picture. Drivers also need to trust what they're billed. Taiwan was one of the first places to put a metering safeguard around charging. Since January 1, 2023, chargers that bill by the kWh have been treated as legal measuring instruments, and every one of them must pass verification before it leaves the factory. As of the end of August 2026, 14,479 charging connectors had done so. BSMI also checks chargers already in service, so the kWh you're billed at a public station can be trusted.
For drivers, that means public charging is backed by a national metering system. For operators and manufacturers, accurate metering is a basic requirement that has to be designed in from the start, not patched in later.
From Charger to Grid Node: What MW-Level Charging Changes
As electric buses and trucks arrive, charging power is heading into megawatt (MW) territory, and bidirectional power transfer is maturing too. Chargers are turning from simple power outlets into active parts of the grid. BSMI says it is planning ahead through R&D programs: tracking international developments, updating national standards as needed and building testing capacity. It aims to offer testing services in Taiwan by 2030, which should cut certification time and cost for manufacturers.
Standards First, Then Scale
Taiwan's EV charging rules are coming together. Voluntary certification has become mandatory inspection, and one-time metering checks now come with ongoing market surveillance. For companies building charging infrastructure, understanding these standards early can decide whether a product enters the market smoothly and earns users' trust. At eTreego, our products have completed the relevant inspection procedures and stay aligned with industry standards, and we keep investing in dynamic load balancing technology to prepare for the next generation of higher-power charging.
FAQs
Q：Do home EV chargers in Taiwan need to pass mandatory inspection?
A：Yes. Since July 2026, home chargers up to 30 kW have been subject to mandatory inspection, and the requirement expands to chargers up to 750 kW in 2028. Products that haven't completed type testing and inspection can't be sold or displayed in Taiwan.
Q：How do I know a public charger is billing me accurately?
A：Chargers that bill by the kWh have had to pass legal metering verification before leaving the factory since 2023. BSMI also periodically checks chargers that are already in use.
Q：What's the difference between mandatory inspection and metering verification?
A：Inspection looks at the equipment's electrical safety, such as insulation, heat resistance, electromagnetic compatibility and flame retardancy. Metering verification checks that the kWh figure used for billing is accurate. They are two separate systems that run side by side.
