What type of battery does the BYD e2 use?
2 Answers
The BYD e2 uses Blade Battery, which is a lithium iron phosphate (LFP) Blade Battery. Through structural innovation, the Blade Battery can skip the module during assembly, significantly improving volume utilization and ultimately achieving the design goal of accommodating more battery cells in the same space. Compared to traditional battery packs, the Blade Battery increases volume utilization by over 50%, meaning the driving range can be extended by more than 50%, reaching the same level as high-energy-density ternary lithium batteries. When driving, avoid sudden acceleration, as slamming the accelerator pedal can instantly generate a high current, causing the battery to discharge rapidly and significantly shortening its lifespan. For daily charging, prioritize slow charging over fast charging. Whether fast or slow charging, the principle involves the migration of lithium ions from the positive electrode to the negative electrode under the influence of external electrical energy. However, due to the different migration speeds of lithium ions, frequent fast charging can accelerate battery polarization and reduce battery lifespan. Fast charging in low temperatures may cause lithium dendrites to form on the surface of lithium ions, potentially piercing the separator and particularly affecting battery longevity. Electric vehicles require regular battery inspections, and the battery should not be left in a depleted state for extended periods. If the vehicle is unused for a long time, slow discharge may occur. It is recommended to store the battery fully charged and check its charge level monthly, replenishing it as needed. During regular use, avoid waiting until the car battery is completely depleted before recharging.
The BYD e2 uses BYD's self-developed Blade Battery, which is a power battery based on lithium iron phosphate technology. As someone particularly focused on automotive electrical systems, I can say that structurally, the Blade Battery has a unique design with tightly arranged internal electrodes resembling blades, which enhances energy density and allows the e2 to achieve a range of around 400 kilometers. In terms of performance, it charges quite quickly—under DC fast charging, it can replenish over half its capacity in about 30 minutes, making daily use very convenient. Regarding safety, based on some comparative tests I've conducted, lithium iron phosphate batteries are inherently stable, resistant to fire or explosion, and pass nail penetration tests with ease, giving me peace of mind when driving the e2. Maintenance costs are also low, with an expected battery lifespan of over 10 years, far exceeding some lithium-ion batteries. Overall, the e2's system is not only reliable but also balances practicality and innovation.
