What is the lifespan of domestically produced Tesla batteries?
2 Answers
Domestically produced Tesla batteries have a lifespan of approximately eight years. Below are the specific details: 1. Battery Introduction: Tesla batteries can generally be charged and discharged 300-500 times. The capacity is 83Kw/h, with a density of 200wh/Kg, and a single charge can cover a distance of 480 kilometers. A Tesla battery unit consists of over a dozen small packs, with each small pack composed of more than seventy individual batteries. Tesla uses lithium batteries, which are a type of battery with lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. When the battery capacity degrades to below 80% of its initial capacity, the driving range will significantly decrease. When the battery capacity degrades to below 70%, the battery must be replaced. 2. Advantages of Tesla's Ternary Lithium Battery: Tesla uses ternary lithium batteries due to their good low-temperature discharge performance, high energy density, high charging efficiency, reliable cycle lifespan, and sufficiently safe materials and processes.
When I first got my domestic Model 3, battery lifespan was my biggest concern. Now, after nearly three years and 80,000 kilometers, the official app shows the battery health is still at 95%. For daily commuting, I’m used to shallow charging and discharging, rarely letting the charge drop below 20%, and using superchargers no more than twice a month. The service center technician reminded me that the lifespan of LFP batteries mainly depends on cycle counts—on average, they retain over 80% capacity after 2,000 cycles, which translates to around 500,000 kilometers. The battery temperature management system is also excellent, with winter range loss being quite reasonable. As long as you avoid frequently leaving it at low charge, driving it for ten years is totally feasible.
