Can the battery of a Zhidou still be used after 5 years?
1 Answers
It depends on the specific usage conditions of the owner. Generally, the battery of a new energy vehicle can last 7-8 years. It is recommended to visit a maintenance facility to test the battery and check its performance before deciding whether to replace it. The classification of new energy batteries is introduced as follows: Lithium Iron Phosphate (LiFePO4) Battery: Lithium iron phosphate batteries have excellent thermal stability, are safe, cost-effective, and have a long lifespan, but they have low energy density and are sensitive to low temperatures. The internal chemical composition begins to decompose when the battery temperature reaches 500-600°C, and they do not catch fire or explode due to punctures, short circuits, or high temperatures, with a relatively long service life. However, the vehicle's range is generally limited, and when the temperature drops below -5°C, charging efficiency decreases, making them unsuitable for winter charging in northern regions. Ternary Lithium Battery: Ternary lithium-ion batteries have high energy density, long cycle life, and are resistant to low temperatures, but they have insufficient stability at high temperatures. They can achieve the highest energy density, but their high-temperature performance is relatively poor. For pure electric vehicles with range requirements, they are the mainstream choice and are suitable for northern climates, as the battery remains more stable in low temperatures.
