Embodiment
Below execution mode of the present utility model is elaborated.It is emphasized that following explanation is only exemplary, instead of in order to limit scope of the present utility model and application thereof.
Consult Fig. 1 a and Fig. 1 b, according to embodiment of the present utility model, a kind of battery equipment integrated with housing comprises housing, be arranged at the equipment mainboard (not shown) in housing and battery module, battery module comprises main battery module and auxiliary battery module, main battery module comprises cell containing cavity and is positioned over the main battery in cell containing cavity, main battery charge-discharge circuit on the Electrode connection equipment mainboard of main battery, housing comprises at least one plastic casing part 100 (it is be molded over together that Fig. 1 a decomposes housing 100 two parts shown actual), auxiliary battery module comprises the flexible battery 200 of integrated injection molding in plastic casing part 100.Plastic casing part 100 can be the housing at the equipment back side, and the thickness increase of the plastic casing that the plastic casing part 100 after shaping is more conventional is no more than 1mm.Plastic casing part 100 offers the through hole 102 of feed, and the electrode of flexible battery is electrically connected to the boosting battery charge-discharge circuit on equipment mainboard by this through hole 102.Feed through hole can adopt conduction design, and the electrode of flexible battery can be electrically connected with the conductor in feed through hole, and conductor forms contact on the inner surface of plastic casing part 100.Feed through hole also can be that itself is nonconducting, and the electrode of flexible battery also can directly extend past feed through hole and form contact on the inner surface of plastic casing part.Preferably, contact can be connected with the charge-discharge circuit on equipment mainboard by metal clips structure, to ensure the reliability of electrical contact.
In an advantageous embodiment, equipment mainboard is also provided with the electric quantity detecting circuit of the dump energy for detecting main battery and flexible battery.Electric quantity detecting circuit can be ADC (analog to digital converter) testing circuit.
In a kind of preferred embodiment, be arranged on removably on equipment with the integrated plastic casing part of auxiliary battery module, this dismountable structure is that the operation and maintenance of equipment brings more flexibility.
In example as shown in Figure 2, the chip on equipment mainboard can adopt SN8200 chip, and chip circumference is provided with relevant peripheral circuit, comprises main battery A-BAT and boosting battery B-BAT charge-discharge circuit separately and respective ADC testing circuit ADC1, ADC2.The contact of main battery A-BAT and boosting battery B-BAT, except comprising positive and negative electrode contact, can also comprise respective battery identification pin A_ID, B_ID, and it can be used for identifying battery ID.
During work, main battery module and auxiliary battery module control by the power management chip on equipment mainboard, and power management chip can be monitored battery electric quantity by ADC testing circuit ADC1, ADC2 and can determine by which battery to system power supply.Such as, when power management chip monitor main battery module (can be product first wife battery usually) exhaust electricity soon time, the auxiliary battery module on housing can be switched to, by housing powered battery.In addition the software Non-follow control power switching also can installed by equipment.When equipment charge, not only can charge to first wife's battery of main battery module, also the housing battery of auxiliary battery module be charged simultaneously, to facilitate user to carry out charging operations, ensure that equipment obtains sufficient electricity with less operation and shorter time.
