中文
含义
安装的电池组与主机不兼容。BMS通讯协议不匹配或电池ID校验失败，机器拒绝使用该电池。
常见原因
- 安装了其他戴森型号的电池（如V7电池用于V8机身）
- 购买的非原装兼容电池通讯协议与主机版本不符
- 电池固件版本过旧，与主机新固件不兼容
- 电池更换电芯后BMS数据丢失或参数改写
- 主机固件更新后不再支持旧版电池ID
自助排查
- 确认电池型号与主机型号匹配（检查机身和电池上的型号标签）
- 尝试另一块确认兼容的原装电池——若正常则说明原电池不兼容
- 如果使用非原装电池，联系卖家确认兼容性参数
- 检查电池和主机触点之间的连接是否完全贴合
- 若原装电池出现此问题，电池或主机可能有故障，需送修检测
English
Meaning
The installed battery pack is incompatible with the main unit. The BMS communication protocol does not match, or the battery ID verification fails, so the machine refuses to use this battery.
Common Causes
- A battery from a different Dyson model installed (e.g., V7 battery in a V8 body)
- Third-party compatible battery with a communication protocol mismatch against the host firmware
- Battery firmware too old to be compatible with an updated main unit firmware
- Battery cells replaced without reprogramming the BMS, causing corrupt identification data
- Main unit firmware update that no longer supports older battery ID revisions
Self-Check Steps
- Verify the battery model number matches the vacuum model (check labels on the battery and body)
- Test with a different known-compatible genuine battery — if the second battery works, the first is incompatible
- If using a third-party battery, contact the seller to confirm compatibility parameters
- Check that the battery and host terminals are making full contact when seated
- If a genuine original battery triggers E13, either the battery or the main unit has a fault — Dyson service inspection is needed
