What type of battery does the BYD Qin use?

[Aaron]

BYD Qin uses BYD lithium iron phosphate (LiFePO4) batteries. The total voltage is 500V with an energy capacity of 13 kWh, and the single-cell voltage of the lithium iron phosphate battery is 3.2V. The following are the characteristics of lithium iron phosphate batteries: 1. High energy density. In 2019, some excellent battery manufacturers achieved levels of 175-180 Wh/kg, with a few advanced manufacturers using lamination processes and larger capacities reaching up to 185 Wh/kg. 2. Excellent safety performance. The cathode material of lithium iron phosphate batteries has stable electrochemical properties and a steady charge-discharge platform. Therefore, the battery structure does not change during charging and discharging, preventing combustion or explosion. Even under special conditions such as short circuits, overcharging, crushing, or puncturing, the battery remains very safe. 3. Long cycle life. Lithium iron phosphate batteries generally have a cycle life of 2000 cycles, with some even exceeding 3500 cycles. For the energy storage market, the requirement is 4000-5000 cycles, ensuring a service life of 8-10 years, which is higher than the 1000+ cycles of ternary batteries.

The BYD Qin primarily uses lithium iron phosphate (LFP) batteries, featuring BYD's self-developed Blade Battery technology. Having driven the Qin PLUS DM-i, I found its battery range truly impressive—it can cover over 100 km on pure electric power, which is more than sufficient for daily commutes. Charging is hassle-free, supporting fast charging that reaches 80% in just half an hour, whether using residential charging piles or workplace outlets. The battery boasts high safety, with puncture-resistant testing showing minimal fire risk, adding peace of mind on the road. A downside is the 10%-20% winter range drop, requiring extra attention to insulation. Overall, these batteries offer long lifespans (officially over 8 years) and low maintenance costs. While replacements aren’t cheap, they’re cost-effective. I always highlight these practical points when recommending it to friends to avoid unnecessary expenses.

I often drive the BYD Qin, which uses lithium iron phosphate blade batteries that charge quickly and maintain stable range. A 50-kilometer pure electric commute is more than enough, and the electricity cost is super economical, averaging just a few dozen yuan per month. After two years, the battery shows no issues—great stability with minimal temperature impact. Fast charging gets it fully powered in half an hour, and overnight home charging is also cost-effective. It boasts strong safety performance, with no worries about overheating or short circuits. Just a heads-up: in winter, try to use less AC as it drains the battery faster. Overall, it offers high cost-effectiveness, and long-distance travel doesn’t bring charging anxiety. The Qin’s battery design is truly thoughtful, making daily driving highly comfortable.
