How to distinguish a good electric vehicle lithium battery?

The battery capacity is divided, and each cell of the high-quality lithium 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. Advanced spot welding, higher craftsmanship, high-quality lithium 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. During welding, the computer automatically monitors the current through the battery. Welding, if the welding is not strong, alarm and stop! Finished product aging detection, strict standards, each group of high-quality lithium batteries will use domestic advanced aging equipment to perform 100% aging sub-capacity detection 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 for high-quality lithium batteries to support the most advanced BMS protection system with research and development patents in China. Effectively guard and protect the electronic components of the system against water, high temperature, oxidation, impact) and other functions, and protect the battery pack during normal use (overcharge, overdischarge, short circuit, undervoltage, overcurrent, temperature control). Detail 5: The outer packaging of the magical customized four-proof and four-tracking battery is on the exterior packaging. The high-quality lithium battery also has design invention patents. All outer boxes are made of 1mm alloy material and high-temperature spraying technology to achieve collision, dust, 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.
