🔌 电动车充电费用计算器（电量百分比、损耗、续航）EV Charging Cost Calculator (Battery %, Losses, Range)
按电池容量和充电前后的电量百分比（或直接按充入电量）算充电费用，计入充电损耗（默认效率 90%），可选能耗（kWh/100 km 或 mi/kWh）算出增加的续航和每 100 km（100 英里）的电费。适用于特斯拉和其他电动车。本地处理。Work out the charging cost from the battery capacity and the charge level before and after (or straight from the energy added), including charging losses (90% efficiency by default). Add the consumption (kWh/100 km or mi/kWh) to see the range added and the cost per 100 km (100 miles). Works for Tesla and any other EV. Processed locally.

如何使用「电动车充电费用计算器（电量百分比、损耗、续航）」？How do I use the EV Charging Cost Calculator (Battery %, Losses, Range) tool?
在「电动车充电费用计算器（电量百分比、损耗、续航）」中，填写「输入方式」、「电池可用容量 kWh」、「充电前电量 %」、「充电后电量 %」、「充入电量 kWh」等参数，结果会随输入实时计算并显示在下方。In the EV Charging Cost Calculator (Battery %, Losses, Range): Fill in "Input", "Usable battery capacity, kWh", "Charge before, %", "Charge after, %", "Energy added, kWh"; results are recalculated instantly as you type.
为什么要算充电损耗？Why include charging losses?
充电时一部分电变成热量（充电器、电池和电池加热/冷却），所以电表计的电比进入电池的多。家用慢充常见效率约 85–90%，天冷时更低。Some energy is lost as heat in the charger and battery (and in heating or cooling the battery), so the meter records more than goes into the pack. Home AC charging is often about 85–90% efficient, and less in cold weather.
电池容量填多少？What battery capacity should I enter?
填可用容量（usable），不是标称总容量。不同车型和年份差别较大，可以在车辆说明书或制造商网站上查。Use the usable capacity, not the gross figure. It varies by model and year; check the owner's manual or the manufacturer's website.
超级充电站怎么算？What about Superchargers?
超级充电站和公共充电桩按各自标价计费（有的按 kWh，有的按分钟），价格随地区和时段变化。把标价（每 kWh）填进电价，效率可设为 100%，因为计费的就是送出的电量。Superchargers and public chargers charge their own posted prices (per kWh or per minute) that vary by location and time. Enter the posted per-kWh price and set efficiency to 100%, since you pay for the energy delivered.
能举个计算实例吗？Can you show a worked example?
例如在「电动车充电费用计算器（电量百分比、损耗、续航）」中填 输入方式 = 充入电池的电量 kWh，充入电量 kWh = 40，充电效率 % = 100，电价（每 kWh） = 0.2，能耗单位 = kWh/100 km，结果区显示：充入电池：40 kWh；从电网取电（含损耗）：40 kWh；损耗：0 kWh；充电费用：8.00；ℹ 电网取电 = 充入电量 ÷ 效率；家用交流慢充效率常见 85–90%，直流快充约 90–95%；超级充电站和公共桩按其标价计费For example, entering Input = Energy into the battery, kWh, Energy added, kWh = 40, Charging efficiency, % = 100, Electricity price per kWh = 0.2, Consumption unit = kWh/100 km in the EV Charging Cost Calculator (Battery %, Losses, Range) gives: Energy into the battery: 40 kWh; Energy from the grid (with losses): 40 kWh; Losses: 0 kWh; Charging cost: 8.00; ℹ grid energy = energy added ÷ efficiency; home AC charging is often 85–90% efficient and DC fast charging about 90–95%; Superchargers and public…
哪些输入会被检查？Which inputs are validated?
「电动车充电费用计算器（电量百分比、损耗、续航）」会检查这些输入——「电池可用容量 kWh」、「充入电量 kWh」：所选方式用到时必须填写，须大于 0；「充电前电量 %」：所选方式用到时必须填写；「充电后电量 %」：可留空；「充电效率 %」：所选方式用到时必须填写，须大于 0 且不超过 100；「电价（每 kWh）」：所选方式用到时必须填写，不能为负数；「能耗（可选）」：须大于 0；绝对值超过 10¹⁵ 的数也会被拒绝。不符合时结果区显示具体提示，不会给出数字。The EV Charging Cost Calculator (Battery %, Losses, Range) checks its inputs — "Usable battery capacity, kWh", "Energy added, kWh": required when the chosen option uses it, must be greater than 0; "Charge before, %": required when the chosen option uses it; "Charge after, %": optional; "Charging efficiency, %": required when the chosen option uses it, must be more than 0 and at most 100; "Electricity price per kWh": required when the chosen option uses it, cannot be negative; "Consumption (optional)": must be greater than 0; numbers above 10¹⁵ in absolute value are rejected too.
