Electric bicycle batteries usher in 2 industry standards
The electric bicycle battery meets 2 industry standards in July 1, 2018, GB/T 22199.1-2017, the first part of the valve controlled lead-acid battery, the technical conditions, the GB/T 22199.2-2017, the second parts of the valve controlled lead-acid battery, the product variety and the specification, the standard of the two electric bicycle batteries will be formal Execute. This is also the 2 industry standards for the electric bicycle battery industry since the implementation of the GB/T 22199-2008 "sealed lead acid battery" in 2008.
In July 1, 2018, GB/T 22199.1-2017 "first parts of valve controlled lead-acid battery for electric power assisting vehicles: technical conditions", GB/T 22199.2-2017, "second parts of valve controlled lead-acid battery for electric power assisting vehicles: product varieties and specifications", two electric bicycle battery standards will be formally implemented. This is also the 2 industry standards for the electric bicycle battery industry since the implementation of the GB/T 22199-2008 "sealed lead acid battery" in 2008.
It is understood that the upcoming GB/T 22199.1-2017 "first parts of valve controlled lead-acid battery for electric power booster" and "technical conditions" and "second parts of valve controlled lead-acid battery for electric power assisting vehicles: product varieties and specifications" were added and revised on the basis of the 2008 version of the industry recommendation standard. It is more suitable for the development of electric vehicle lead-acid battery industry.
The implementation standard is to split the previous standard into two parts (technical conditions and product varieties and specifications) to make the standard more detailed and more specific; secondly, a more detailed specification of some performance indicators for lead-acid batteries, such as increasing the energy density, is made. The technical requirements of fast charging capacity, battery life reliability, flame retardancy and constant power discharge capacity are required, and the requirements of low temperature capacity are modified, and the technical requirements of combination consistency, charging acceptance, sealing reaction efficiency and over discharge are deleted. From the overall point of view, the new version of the new version of the electric vehicle lead-acid battery is recommended, and the performance requirements of the product are further improved, and it is also more in line with the industrial development.
It is worth mentioning that in GB/T 22199.1-2017 "the first part of VRLA battery used for electric power assisting vehicle: technical conditions", the requirements for the use of the users are especially increased, especially in the use of battery, charger, charging, idle battery placement, etc. The purpose is to ensure the safety of electric bicycles while ensuring the power.
It is understood that the two industry recommended standards will be drafted by the main research institutions and key manufacturers of lead-acid batteries charger, such as the Shenyang battery research institute and the super Wei group. The practical standard that is first written to the industry standard is the electric bicycle lead battery enterprise such as super Wei Group, which is summed up in combination with the long-term production practice and the actual feedback from the comprehensive consumer side to the product.
With the rapid development of lithium batteries, lead-acid batteries seem to be heading for "decline". However, for the long-term in-depth study of lead-acid battery industry, lead-acid battery still has a vigorous vitality. Yang Yusheng, the academician of the Chinese Academy of Sciences, has said that the two advantages of lead-acid battery with high safety and low cost are still unparalleled by lithium batteries at present. The development of batteries comes from materials, innovation in battery materials, and Research on energy density and service life, which can keep the two advantages of lead-acid batteries to the maximum. The lead-acid battery will continue to move forward.
