▍What is ANATEL Homologation?
ANATEL is a short for Agencia Nacional de Telecomunicacoes which is Brazil governmental authority to certified communication products for both compulsory and voluntary certification. Its approval and compliance procedures are the same both for Brazil domestic and abroad products. If products are applicable to compulsory certification, the testing result and report must be in line with the specified rules and regulations as requested by ANATEL. Product certificate shall be granted by ANATEL first before product is circulated in marketing and put into practical application.
▍Who is liable for ANATEL Homologation?
The Brazil governmental standard organizations, other recognized certification bodies and testing labs are ANATEL certification authority for analyzing the production system of manufacturing unit, such as product design process, procurement, manufacturing process, after service and so on to verify the physical product to be complied with Brazil standard. Manufacturer shall provide documents and samples for testing and assessment.

With the rapid increase in the demand for energy storage batteries, the shipment volume has increased significantly, and a large number of related enterprises have entered the energy storage market. In order to improve the image and quality of their products for a strong product competitiveness, and meet the needs of various countries or regions, more and more enterprises began to test as per UL 9540A. To let you better understand this standard, the following is a simple summary for the standard requirements.
The purpose of cell testing is to collect the basic parameters of cell thermal runaway (such as temperature, gas composition, etc.) and determine the method of thermal runaway;
The process of cell testing: The cell is pretreated to charge and discharge in two cycles according to the manufacturer’s regulations; The cell is placed in a sealed gas collection tank, which is filled with nitrogen; The cell triggers thermal runaway, with methods including heating, acupuncture, overcharge, etc.; After the end of thermal runaway of the cell, the gas in the tank is extracted for gas analysis; Measure explosion limit data according to the composition of gas group information, get the data of heat release rate and explosion pressure.
