Why doesn't the BYD Han DM use blade batteries?
2 Answers
Actually, it's because the Han DM has an additional power system, making it difficult to reserve a large amount of space to ensure its range, performance, and other conditions are met before using blade batteries. Therefore, the Han DM version uses the traditional BYD lithium iron phosphate battery. Since its launch, the Han series currently has two types of power models: one is the Han EV, and the other is the Han DM (plug-in hybrid). The model features a wheelbase of over 2.9 meters, low fuel consumption, pure electric driving capability, high performance with a 0-100 km/h acceleration in 4.7 seconds, and a price of less than 240,000 yuan.
I often study hybrid technology, and the reason why the BYD Han DM doesn't use Blade Battery is mainly due to different design priorities. Hybrid vehicles rely on the coordinated operation of an internal combustion engine and an electric motor, with a smaller battery capacity primarily used for auxiliary power and energy recovery, making it unnecessary to adopt a high-capacity lithium iron phosphate solution like the Blade Battery. The Blade Battery excels in high safety and long lifespan, but it is larger in weight and volume, making it more suitable for pure electric vehicles like the Han EV to provide long-lasting range. The Han DM opts for more flexible ternary lithium batteries or other lightweight batteries, which enable rapid charging and discharging, cope with frequent start-stop scenarios, reduce overall vehicle weight, and improve fuel efficiency. From a practical standpoint, hybrid systems have lower battery requirements, and the cost of use is more economical, making daily use more hassle-free for users.
