What is the lithium-ion battery for a good electric car?

The battery is divided into capacity, and each cell of the high-quality lithium-ion battery is monitored by the computer for consistency control! The capacity, internal resistance, and voltage of each battery are automatically recorded by the computer according to the content of the scan code. Secondly, all single batteries are sprayed with model capacity, wH, barcode, batch code, and traceable production date code. Advanced spot welding, higher craftsmanship, high-quality lithium-ion batteries use the most advanced spot welding equipment in the country to connect the batteries in series and parallel, and the spot welding position and current are all monitored by computer setting parameters. The computer automatically monitors the current through the battery during welding. False welding, if the welding is not strong, alarm and shut down! Finished product aging test, strict standards, each group of high-quality lithium-ion batteries will use domestic advanced aging equipment to perform 100% aging sub-capacity test on the finished product. When the following two situations occur, the battery will not be shipped. First, when the battery capacity has dropped by more than 0.02% after 3 weeks of cycling, it will not be shipped; when the high temperature aging sub-capacitance voltage (voltage drop) is different, a battery of more than 15mv between each string will not be shipped. The protection board can be customized and the high-quality lithium-ion battery is equipped with the most advanced BMS protection system with research and development patents in China. Effectively prevent the electronic components of the protection system from waterproofing, high temperature, oxidation, impact) and other functions, and protect the battery pack during normal use (overcharge, overdischarge, short circuit, undervoltage, overcurrent, temperature control). The unique customized four-proof and four-tracking battery outer packaging is on the appearance packaging. The high-quality lithium-ion battery also has a design invention patent. All outer boxes are made of 1mm alloy materials and high-temperature spraying technology to achieve anti-collision, dust-proof, waterproof and explosion-proof; at the same time; , All finished products are printed with laser anti-identification codes, which not only guarantees product quality, but is also responsible for every user.
