Basic introduction

Lithium power battery is the main force of power battery. As a new type of high-energy battery successfully developed in the 20th century, lithium power battery has been widely used in military and civil small electrical appliances. At present, the lithium battery in air transportation needs to pass the un39.3 test before transportation. However, the lithium power battery has the characteristics of large volume and large capacity, so it is easy to cause the transportation inconvenience. In order to facilitate the majority of lithium power battery manufacturers and distribution enterprises, CNKI has specially launched large-scale power battery testing projects that can do more than 100V.

Recommended certification
  •  US EPA certification

    US EPA certification

    EPA is the abbreviation of U.S. Environmental Protection Agency. Its main task is to protect human health and the natural environment. EPA is a compulsory certification.

  •  Solid waste testing / solid waste testing

    Solid waste testing / solid waste testing

    In order to prevent and control environmental pollution by solid waste, protect human health, maintain ecological security, and promote sustainable economic and social development, the law of the people's Republic of China on the prevention and control of environmental pollution by solid waste is formulated. After two revisions, the requirements for storage, utilization and disposal of solid waste are stricter. With the rapid development of economy and society, the environmental problems caused by solid waste pollution are gradually emerging. At the same time, the requirements of identification and detection of solid waste and hazardous waste are also gradually improved.

  •  Soil testing

    Soil testing

    Soil is an important part of the environment. Soil environmental monitoring is to determine the environmental quality (or pollution degree) and its change trend by measuring the representative values of factors affecting soil environmental quality. Generally speaking, soil monitoring refers to soil environmental monitoring, which can be divided into regional soil background, farmland soil environment, construction project soil environmental assessment, soil pollution accident and other types of monitoring, including site sampling, sample preparation, analysis method, result characterization, data statistics and quality evaluation and other technical contents.
