车辆充不满的原因较多，如下几个是较常见的情况：
There are many reasons why the car is not fully charged. The following are common situations:
✦ 桩端进行SOC(State Of Charge的缩写，即荷电状态，用来反映电池的剩余容量)阈值保护，比如桩端将SOC保护阈值设置为95%，车辆充电至95%时会立即停止充电。充电桩部分也设置了阈值保护，这时出现充不满的情况，是正常现象。
✦ SOC (state of charge, short for state of charge) threshold protection shall be carried out at the pile end. For example, when the SOC protection threshold is set to 95% at the pile end, the vehicle will stop charging immediately when charging to 95%. The charging pile is also provided with threshold protection. It is normal that the charging is not enough.
✦ 车厂出于安全考虑，会做特别设计，实际充电量往往比标称的电池容量小。
✦ for safety reasons, the vehicle manufacturer will make special design, and the actual charging capacity is often smaller than the nominal battery capacity.
✦ 电池电量正常衰减，一般车辆在使用2、3年后，电池将出现衰减迹象，可能出现电量无法充满。
✦ the battery power normally declines. Generally, after 2 or 3 years of use, the battery will show signs of decay, and the power may not be fully charged.
✦ 车辆检测到某些异常时会主动停止充电，例如电池温度过高。
✦ when the vehicle detects some abnormalities, it will actively stop charging, for example, the battery temperature is too high.
✦ 某些车型会按照驾驶习惯来估算续航里程，驾驶风格比较激烈时会导致估算续航里程较少。
✦ for some models, the endurance mileage will be estimated according to the driving habits. When the driving style is more intense, the estimated endurance mileage will be less.
