System charge construction schematic diagram；If double PSU occur under BBU charge modes occurs short-circuit, the necessary successful switch of BBU first,
Complete standby electricity.And in switching, if BBU is in charging, it is to need conversion time that BBU is changed into power supply state from charged state
, can if the time is oversize, standby TURP changes unsuccessful, therefore need test bbu be cut rapidly from charge mode in this programme
Discharge mode is changed to, if it can, then illustrating without abnormal.Specifically, it is less than if detecting P12V_PSU voltages after 11.4V,
BBU current supply circuits can be opened by bbu charge rate and bbu enable, while mainboard hot plug IC do and switched.
