Energy Storage Battery Brazil Inmetro Certification Guide

Against the backdrop of the global energy transition, energy storage batteries, as the core support for renewable energy, are experiencing explosive growth. Brazil, an emerging market in Latin America, boasts abundant solar and wind energy resources. Coupled with the government’s vigorously promoted National Energy Transition Plan, the demand for energy storage in the country has been on a steady rise.

The Brazilian market holds enormous potential, yet it imposes stringent entry barriers — inmetro certification has become the "passport" for energy storage batteries to enter the Brazilian market. With years of experience in the international certification field, JJR LAB has helped numerous enterprises successfully obtain inmetro certificates and access the Brazilian market through localized services.

Overview of inmetro certification

Inmetro certification is a mandatory product certification system in Brazil, administered by the National Institute of Metrology, Quality and Technology (Inmetro). The certification is designed to ensure that all products sold in the Brazilian market comply with national standards for safety, quality, energy efficiency, and environmental impact.

Both domestically produced and imported goods falling within the scope of the certification catalogue must pass designated tests and audits, and affix the inmetro mark before they can circulate in the market. Therefore, Inmetro certification is a crucial technical barrier and market access threshold that products must overcome to enter and thrive in Brazil.

Detailed Inmetro Certification Requirements for Energy Storage Batteries

In accordance with the requirements of Portaria nº 140, energy storage batteries (including lithium-ion batteries, lead-acid batteries, nickel-cadmium/nickel-metal hydride batteries, etc.) must meet strict certification standards to ensure product safety and compliance with performance requirements.

Taking the widely used lithium-ion energy storage systems as an example, the specific testing requirements are detailed below.

As mandated by the regulations, 4 sets of samples are required for testing, among which Sets 1–3 are samples without a Battery Management System (BMS).

Labeling Requirements for Energy Storage Batteries

(1) Clear labels and information in Portuguese must be provided on the equipment to ensure traceability.

(2) The following labels must be permanently marked on non-removable or non-replaceable components of the product, which can be achieved by means of embossing, stenciling, or affixing:

①　Name, trade name, and National Registry of Legal Entities (CNPJ) of the manufacturer or importer;

②　Commercial name of the product (model and code);

③　Date of manufacture (in the order of day/month/year);

④　Country of origin (economic bloc logos or national flags are not allowed; the specific country must be clearly indicated);

⑤　Batch number, serial number, or other traceability identifiers (if such identifiers can trace the date of manufacture and country of origin, they may replace the corresponding labels for these two items).

(3) In addition to the general labeling requirements above, battery-specific labels must also be marked on the battery itself (on non-removable or non-replaceable components), including battery type, application classification, discharge system, rated voltage, and rated capacity.
