Battery capacity: 1, the battery capacity is under the specified conditions of discharge batteries, fully charged battery can emit electricity, with "C" indicates. 2, the battery capacity is a sign of external battery discharge capacity, a measure of the quality of the merits of the battery and the choice of the most important indicators of the battery. 3, the battery capacity using Ah (ampere hour) to measure. That capacity is equal to the discharge current and discharge duration of the product. Battery Troubles and an external fault: shell cracks, corrosion pole, pole loose, sealed plastic dry. 2, the internal fault: plate curing, the active material shedding, plate gate frame corrosion, plate short circuit, self-discharge, plate doming. Ministry of Industry recently on the "vehicle battery industry norms conditions" open to the public for comments. The specification is intended to strengthen the vehicle battery product stewardship car battery, to prevent redundant construction, promote technological progress and the development of large-scale power battery production enterprises. Specifications for battery manufacturers product specifications, production and technical capabilities put forward specific demands. Specification says batteries, battery power refers to the installation configuration in the car, capable of storing electrical energy and rechargeable, providing energy to drive cars with a device. Including lithium-ion batteries, nickel metal hydride batteries and super capacitors and other power (not including lead-acid type batteries). Power battery production enterprises, including single power battery production enterprises (hereinafter referred to as "monomer production enterprise") and the power battery system manufacturing enterprises (hereinafter referred to as the "System manufacturer"), two types of lithium-ion batteries monomer production lead-acid battery business When the nickel metal hydride battery power monomer production enterprises with an annual capacity of not less than one million watts;;, when an annual capacity of not less than 200 million watts of supercapacitors monomer production enterprises with an annual capacity of not less than 5 MWh. System manufacturer with an annual capacity of not less than 10,000 sets or 200 million watts. Producing a variety of types of monomers and battery power systems business, its capacity should also meet the above requirements. Norms especially for corporate research capability made requests. Battery companies should be equipped with appropriate research and development staff, its proportion of total number of employees accounted for not less than 10% or less than the total number of 100 people; with research and development staff should cover at least four aspects of enterprise product development, including new product technology R & D, product trial and test analysis, the development of tracking technology similar products at home and abroad, corporate standards and revision and other batteries _ _ Wei Li Po battery car battery provided by Shenzhen Wei Lai Po Battery Limited.
