Incorporated by reference to Fig. 9.
Adapter output voltage can directly supply electronic equipment and charge the battery.In battery charging process, battery management circuit 10 pairs of batteries are monitored, and when reaching charge threshold, controlling battery and stopping charging, and controlling battery and externally do not discharge.
When adapter does not have output voltage, battery management circuit 10 controls battery and discharges to electronic equipment, meanwhile, when reaching discharge threshold, controlling battery and stopping electric discharge.Voltage selection module 103 in battery management circuit 10 selects output voltage feedback signal according to user, thus makes voltage output module 104 export the direct voltage of different size.Be respectively 14.6V, 16.8V, 18.2V.After voltage output module 104 output dc voltage, dc voltage boost to the first rated direct voltage, is generally 19V by boosting adjustment module 201 correspondence.Be specially boost chip LM5122 by after dc voltage boost to the direct voltage of 19V, export to electronic equipment.
Boost chip LM5122 adopts the form of cascade, and namely two boost chip LM5122 all export 19V direct voltage.Thus can be used for multiple electronic equipment.
First rated direct voltage is depressured to the second rated direct voltage by reduction regulation module 202 correspondence, is generally 12V.Be specially step-down chip LM3510 or the direct voltage step-down of 19V is become the direct voltage of 12V by step-down chip LM3511.Step-down chip LM3510 or step-down chip LM3511 adopts parallel form, and step-down chip LM3510 or step-down chip LM3511 exports 12V direct voltage respectively, can be used for multiple electronic equipment.
The output of step-down chip LM3511 connects MCU controller and motor handover module, for 12V direct voltage is converted to ± and the direct voltage of 12V.MCU controls to connect battery by SMBus bus, and by RS232 and GPIO_Level1 and peripheral device communication.
Above-mentioned medical electric source control system carries out charge or discharge by management of charging and discharging module 101 pairs of batteries, and namely the direct direct voltage by adapter output converts cell voltage to.And the pressure reduction controlled by voltage isolation module 102 in battery charge and discharge process.Meanwhile, voltage selection module 103 control voltage output module 104 correspondence is adopted to export the direct voltage of different size.The voltage that battery management circuit 10 exports, via after boosting adjustment module 201, can boost to the first rated direct voltage, thus meet the electronic equipment of needs high voltage in equipment.By reduction regulation module 202 to after the first rated direct voltage step-down, the high voltage drop of input can be pressed onto the second nominal DC pressure drop, thus meet the electronic equipment of needs low voltage in equipment.Thus above-mentioned medical electric source control system is without the need to being converted to AC power by cell voltage, circuit module AC power be converted to again in direct current pressure drop supply arrangement uses, but directly direct voltage is converted to the direct voltage of corresponding size, avoid the two times transfer of power supply, the service efficiency of medical electric source control system is improved greatly, avoids energy waste.
