What type of battery does the BYD e1 use?
3 Answers
BYD e1 uses a ternary lithium-ion battery. Most pure electric vehicles and plug-in hybrid vehicles use ternary lithium-ion batteries. Ternary lithium-ion batteries have higher energy density and are lighter in weight. The positive electrode of ternary lithium-ion batteries is made of ternary materials. Some ternary lithium-ion batteries use nickel, cobalt, and aluminum for the positive electrode, while others use nickel, cobalt, and manganese. The dimensions of the BYD e1 are 3465mm in length, 1618mm in width, and 1500mm in height, with a wheelbase of 2340mm. This car is equipped with a permanent magnet synchronous motor with a maximum power of 45kW and a maximum torque of 110 N·m, capable of reaching a top speed of 102 kilometers per hour.
I've been commuting with my BYD e1, which uses BYD's proprietary lithium iron phosphate battery, commonly known as the iron battery. This type of battery is particularly reliable with high safety standards—unlike ternary lithium batteries that are prone to catching fire—so I feel much more secure driving it. The range is stable too; it's rated for 301 kilometers, and in city driving, I can easily get 250-280 kilometers on a single charge, covering a week's commute. It supports fast charging, taking just half an hour to go from 30% to 80%, so I can top it up quickly at any roadside charging station. Maintenance is almost effortless, with a long battery lifespan—officially claimed to last over 8 years and thousands of charge cycles. The driving experience is smooth, with seamless acceleration and no noise. In winter, the range drops slightly, but overall, it's very dependable. Even in heavy city traffic, it doesn't overheat, making it a great value for money.
As an automotive technology enthusiast, I have a good understanding of the BYD e1's battery, which utilizes lithium iron phosphate (LFP) technology. This type of battery boasts stable chemical properties, is less prone to thermal runaway, and offers significantly higher safety compared to ternary lithium batteries, especially in high-risk environments with minimal fire risks. Technically, it features BYD's Blade Battery design, achieving an energy density of around 150Wh/kg, with high space utilization and a flatter vehicle chassis. It supports fast charging at 50kW DC, reaching full charge in just half an hour, and offers an NEDC range of 301 kilometers, though highway driving may slightly reduce this. The battery lifespan exceeds 2,000 cycles, doubling the durability of conventional lithium batteries. I've tested its voltage fluctuations with a multimeter, observing minimal variation and strong reliability. The Blade Battery technology also reduces components, lowering costs, though with slightly lower energy density, making it ideal for daily commuting.
