How to choose an electric vehicle lithium battery pack?

With the support of national policies and the introduction of the new national standard for electric vehicles, the development of lithium battery packs has ushered in a huge opportunity. At present, the lithium battery industry has formed an intact industrial chain with a high degree of specialization and engineering. Detail 1: The battery capacity is divided, the whole computer monitors each cell of the high-quality lithium battery through the consistency control! All batteries are scanned on the capacity and the capacity of the equipment is divided, and the computer automatically records the capacity and content of each battery according to the scanned code content Resistance, voltage. 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 battery packs, use the most advanced spot welding equipment in the country to connect the batteries in series and parallel. The spot welding position and current are all monitored by computer setting parameters, and the computer connects the current through the battery during welding. Automatic monitoring, false welding, if the welding is not strong, the alarm and shutdown! Detail 3: Product aging test, strict standards Each group of high-quality lithium batteries will use domestic advanced aging equipment to conduct a 100% aging sub-capacity test on the product. When the battery exhibits the following two conditions, it will not be shipped. At the top of the list, when the battery capacity drops more than 0.02% after being cycled for 3 weeks, it will not be shipped; when the high-temperature aging sub-capacity voltage differs, a set of batteries exceeding 15mv between each string will not be shipped. Detail 4: The protection board can be customized and the high-quality lithium battery is matched with the most advanced and patented BMS protection system in China. Effectively guard and protect the electronic components of the system from waterproof, high temperature, oxidation, impact and other functions, and protect the lithium battery pack during normal use (overcharge, overdischarge, short circuit, undervoltage, overcurrent, temperature control). Detail 5: Jointly customize the outer packaging of the four-proof and four-traceable battery. The high-quality lithium battery pack also has a design and invention patent. All outer boxes are made of 1mm alloy materials and high-temperature spraying technology to achieve anti-collision, dust-proof, and waterproof. Explosion-proof; together, all products are marked with laser anti-identification codes, not only to ensure product quality, but also responsible for every user.
