温度与电池 [2]

天气

  • →10–30%的暂时范围损失是正常的，并在变暖时恢复
  • →冷电池充电缓慢—避免强制直流快速充电，直到电池变热
  • →导航到超级充电器以触发自动电池预调节
  • →接通电源时对机舱进行预处理—使用电网供电，而不是电池

天气热

  • →持续加热+高充电水平=随着时间的推移永久容量损失
  • →在非常炎热的气候下，将每日充电限制降至70–75% （定期高于35°C ）
  • →在阴凉处或车库停车—环境温度比大多数人意识到的更重要
  • →机舱预处理还可以激活电池冷却—在插入电源时使用

低温下的范围损失 [3]

−1°C / 30°F−16.5%167 miles
−7°C / 20°F−27.3%145 miles

长期储存

让您的特斯拉闲置两周以上？请按照以下步骤尽量减少降解。

  1. 1

    充电至50% （ ± 10% ）

    这是锂电池的理想存储电压—每个电池约3.8V。

  2. 2

    尽可能接通电源

    即使是1级充电器，也可以让汽车管理自己的温度和吸血鬼排水管。拔掉插头，它会慢慢排水。

  3. 3

    储存在阴凉干燥处。

    10–20°C （ 50–68°F ） ，湿度低于85%。避免阳光直射和极端温度波动。

  4. 4

    如果拔下插头，则每月检查一次

    如果低于40% ，最高可充值50%。切勿将其长时间置于20%以下。

这些指南将特斯拉的官方建议与广泛接受的电动汽车社区最佳实践相结合。具体结果将因车型、软件版本、当地气候和驾驶风格而异。

LFP vs. Nickel-based chemistry

Tesla uses two different battery chemistries, and the right charging strategy depends on which one you have:

  • LFP (Lithium Iron Phosphate) — used in Model 3/Y Standard Range. Can be charged to 100% regularly without penalty. Tesla recommends charging to 100% weekly for calibration.
  • NMC/NCA (Nickel-based) — used in Long Range, Performance, Model S/X, and Cybertruck. Charge daily limit to 80%, only to 100% before a long trip.

Check your Charging screen: if it recommends 100% for daily use, you have LFP. Otherwise, it's nickel-based.

Preconditioning: the underrated habit

One habit that costs you nothing in range and has an outsized impact on battery longevity:

Use the Tesla app to precondition the battery while plugged in (Climate → Start, 30–45 minutes before departure). This warms or cools the battery using grid power, not your battery's energy.

Benefits: Faster charging, more efficient driving in extreme temperatures, and less thermal stress on the pack. Cold weather? Let navigation to a Supercharger trigger automatic preconditioning. Hot climate? Pre-cool while plugged in before you drive away.

Additional battery chemistry and care questions

How do I know if my Tesla has an LFP or nickel-based battery?
The quickest check is the Charging screen itself: if Tesla recommends charging to 100% for daily use, your car has an LFP pack; if it caps the daily slider around 90% with a warning about only charging to 100% before a trip, it's nickel-based (NCA/NMC). As a rule of thumb, current Standard Range / RWD versions of Model 3 and Model Y use LFP, while Long Range and Performance trims, plus every Model S, Model X and Cybertruck, use nickel-based cells — see the variant tables on our battery specs page to confirm your exact car.
Why is the daily charge limit 80% but the storage limit 50%?
They're solving different problems. A daily limit balances range against the modest extra stress of sitting near full charge between short trips, so 80% is a comfortable middle ground for a car that's used regularly. Long-term storage removes the driving entirely, so the priority shifts to minimising slow calendar ageing while the car sits idle for weeks — and for that, a battery held around the middle of its range (50%) ages more gently than one left near either end.
Is it OK to precondition manually, not just in cold weather?
Yes. Preconditioning while the car is still plugged in draws the energy from the wall rather than the battery, so it costs you nothing in range whenever you use it — it's just most noticeable in winter, when it also warms the pack for faster charging. It's equally worth using on a hot day to cool the cabin before you get in, or a few minutes before a Supercharger stop so the pack is at the right temperature to accept power quickly.
Does a software update change my recommended charge limit?
Occasionally. Tesla periodically refines its battery management logic through software, which can nudge the recommended daily limit or how the charging slider behaves — particularly after a major update. It's worth glancing at the Charging screen after a big software release to confirm your usual settings still reflect the current guidance for your car's chemistry.
