电池限制设置Battery Limit setting

电池限制选项是 UEFI 设置,可更改 Surface 设备电池的充电方式并延长其使用时间。Battery Limit option is a UEFI setting that changes how the Surface device battery is charged and may prolong its longevity. 当设备连续连接到电源时(例如,当设备集成到展台解决方案中时)建议使用此设置。This setting is recommended in cases in which the device is continuously connected to power, for example when devices are integrated into kiosk solutions.

电池限制的工作原理How Battery Limit works

在"电池限制"上设置设备会更改用于为设备电池充电的协议。Setting the device on Battery Limit changes the protocol for charging the device battery. 启用电池限制后,电池电量将限制为最大容量的 50%。When Battery Limit is enabled, the battery charge will be limited to 50% of its maximum capacity. Windows 中报告的费用级别将反映此限制。The charge level reported in Windows will reflect this limit. 因此,它将显示电池的充电率最高为 50%,并且不会超出此限制。Therefore, it will show that the battery is charged up to 50% and will not charge beyond this limit. 如果在设备充电超过 50% 时启用电池限制,电池图标将显示设备已接通电源,但正在等待,直到设备达到最大充电容量的 50%。If you enable Battery Limit while the device is above 50% charge, the Battery icon will show that the device is plugged in but discharging until the device reaches 50% of its maximum charge capacity.

支持的设备Supported devices

电池限制 UEFI 设置内置于最新的 Surface 设备中,包括 Surface Pro 7+、Surface Pro 7 和 Surface Laptop 3。The Battery Limit UEFI setting is built into the latest Surface devices including Surface Pro 7+, Surface Pro 7, and Surface Laptop 3. 较早的设备需要 Surface UEFI固件更新,可通过 Windows 更新或通过 Surface 支持站点上的 MSI 驱动程序和固件 包获取Earlier devices require a Surface UEFI firmware update, available through Windows Update or via the MSI driver and firmware packages on the Surface Support site. 选中 "为必须 长时间插入的 Surface 设备启用"电池限制",以针对每个受支持的设备所需的特定 Surface UEFI 版本。Check Enable "Battery Limit" for Surface devices that have to be plugged in for extended periods of time for the specific Surface UEFI version required for each supported device.
