BYD is the only automobile manufacturer in the world that masters the three main technologies of motor, electronic control and battery in the field of electric vehicles. These three core technologies enable BYD to gain a firm foothold in the era of great development of electric vehicles, so that it can compete head-on with brands such as BBA and Tesla.

　　As a service provider of customized lithium batteries for nearly 20 years, SES Power has always been full of respect for BYD. Our 12V100Ah, 12V200Ah, 24V100Ah, 24V200Ah, 36V100Ah, 48V50Ah, 48V100Ah, 48V200Ah, 72V100Ah and other products are often BYD's square aluminum-shell lithium iron phosphate battery will be used. What are the advantages of BYD's power battery technology? Now, where is the blade battery, the world's safest power battery launched by BYD?

　　A: Through structural innovation, "blade batteries" can skip "modules" when grouped, which greatly improves the volume utilization rate, and finally achieves the design goal of loading more cells in the same space; compared with traditional battery packs, the volume utilization rate of the "blade battery" has increased by more than 50%, which means that the cruising range can be increased by more than 50%, reaching the same level as the high energy density ternary lithium battery.

　　B: The design of the "blade battery" enables it to generate less heat and dissipate heat quickly during a short circuit. While reducing assembly costs, this technology can comprehensively improve the structural strength of the battery pack and maximize the safety of users.

　　C: The blade battery adopts the lithium iron phosphate system, and at the same time optimizes the internal design of the battery cell and uses innovative materials, so that the blade battery can pass the most stringent safety test-acupuncture test, and its performance in the "acupuncture test"" Excellent."

　　PS: Acupuncture experiment is currently the most commonly used method to simulate the short circuit in lithium ion batteries. By inserting a steel needle into the lithium ion battery, a short circuit between the positive and negative electrodes is caused, and a large amount of heat is locally generated, so as to realize the Simulation of short circuits in Li-ion batteries.

　　In terms of safety, we must explain the differences in the safety performance of different types of lithium batteries.

　　With the advantages of high energy density and excellent cycle performance, lithium-ion batteries have achieved great success in 3C products, energy storage and power batteries, but high energy density also brings greater safety hazards, especially when an internal short circuit occurs, a large amount of heat is locally generated in the lithium-ion battery in a short period of time, causing the decomposition of the electrolyte and active materials, generating more heat, and it is very easy to cause thermal runaway, resulting in serious safety problems.

　　The lithium iron phosphate battery refers to the lithium ion battery using lithium iron phosphate as the positive electrode material. The characteristics of this type of battery are that it does not contain precious metal elements (such as cobalt, etc.); in actual use, lithium iron phosphate batteries have the advantages of high temperature resistance, strong safety and stability, and better cycle performance.

　　The structural innovation of the blade battery and the safety of lithium iron phosphate, more cells, and greater energy storage have resulted in an ultra-safe and ultra-long-range blade battery.
