Selection details of lithium-ion battery packs for electric vehicles

Details of the selection of lithium-ion battery packs for electric vehicles: 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 processing date code. Detail 2: Advanced spot welding, higher craftsmanship, high-quality lithium-ion battery packs, using the most advanced spot welding equipment in China to connect the batteries in series and parallel, and the spot welding position and current are all monitored by computer setting parameters, and the computer is connected through the battery during welding. Automatic current monitoring, false welding, if the welding is not strong, alarm and shutdown! Detail 3: Finished product aging detection, strict standards Each group of high-quality lithium-ion batteries will use domestic advanced aging equipment to perform 100% aging sub-capacity testing 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 differs, a battery of more than 15mv between each string will not be shipped. Detail 4: The protection board can be customized and the high-quality lithium-ion battery is matched with the most advanced BMS protection system in China with research and development patents. Effectively prevent and protect the electronic components of the system from waterproofing, high temperature, oxidation, impact and other functions, and protect the lithium-ion battery pack during normal use (overcharge, overdischarge, short circuit, undervoltage, overcurrent, temperature control). Detail 5: Unique customized four-proof and four-tracking battery outer packaging is on the exterior packaging. The high-quality lithium-ion battery pack also has a design invention patent. All outer boxes are made of 1mm alloy material and high-temperature spraying technology to achieve collision, dust and water resistance. , Explosion-proof; at the same time, all finished products are marked with laser anti-identification codes, which not only guarantees product quality, but is also responsible for every user.
