Taiwan Taiwan promulgated four national standards related to EV charging equipment

Tesla’s charging standard was newly added

On December 7, 2021, the Bureau of Standards, Metrology and Inspection of the Taiwan Ministry of Economic Affairs promulgated the four revised national standards for EV (Electric Vehicle) charging equipment (CNS). According to the Ministry of Economic Affairs, this revision adds the Tesla charging standard (TPC). The aim of the revision is to expand the choice of standards that can be used in charging facilities to facilitate user convenience and promote the development of the EV industry. The breakdown of the four national standards and the outline of the revisions are as follows:

National standard name

Content of revision

1. CNS 15511-1

“Electric vehicle conductive charging system-Part 1: General requirements”

Adds requirements for EV charging protocols.
2. CNS 15511-23

“Electric vehicle conductive charging system-Part 23: D.C. electric vehicle charging station”

Adds requirements for EV charging protocols.
3. CNS 15700-2

“Plugs, socket-outlets, vehicle connectors and vehicle inlets-Conductive charging of electric vehicles-Part 2: Dimensional compatibility and interchangeability requirements for a.c. pin and contact-tube accessories”

Adds relevant specifications such as the dimensions of the AC charging interface used in the Tesla charging standard (TPC).
4. CNS 15700-3

“Plugs, socket-outlets, and vehicle couplers-Conductive charging of electric vehicles-Part 3: Dimensional compatibility and interchangeability requirements for d.c. and a.c./d.c. pin and tube-type contact vehicle couplers”

Adds relevant specifications such as the dimensions of the DC charging interface used in the Tesla charging standard (TPC).

Since the Tesla charging standard (TPC) has been newly added in this revision, it is necessary to conduct tests based on the relevant requirements in the national standards on charging infrastructure that adopts the standards.
