确认低压电池的状态。
注如果功率转换系统 (PCS) 支持启用 2 分钟后,出现VCLEFT_a478_LVBMS_MOSFET_Open或VCBATT_a478_LVBMS_MOSFET_Open警告,说明低压电池尚未自动恢复。可以通过触摸屏或 Toolbox 尝试手动进行自动恢复:
- 触摸屏:
- Toolbox:运行ActionPROC_VCFRONT_X_RECONNECT-LV-BATTERYSearch for routine in ToolboxLVBMS Reconnect LV BatteryLow Voltage / Power Distribution - Close MOSFET
注如果通过上述步骤并未成功完成低压电池自动恢复,请使用 Tesla 锂离子电池充电器(仍在开发中)进行电池恢复。- 确认电池并未处于高电流放电或自保护状态。
- 转至Service Mode > Low Voltage > Power Distribution > LV Battery,确认低压电池充电状态在上升。
