The dull and stereotyped handheld device of a kind of super long standby time double cell
Technical field
The utility model relates to dull and stereotyped handheld device power-supply system, especially a kind of dull and stereotyped handheld device of double cell with super long standby time function.
Background technology
Along with the update cycle of mobile phone is more and more faster, most consumers has all been changed mobile electronic devices such as smart mobile phone, its smart mobile phone has independently operating system, the program that third party service providers such as software, recreation provide can be installed voluntarily by the user, so under function and the configuring condition, whether can become the major criterion that the consumer selects machine by super long standby time to dull and stereotyped handheld device.Yet, for realizing long-time cell phone standby, cause most mobile-phone manufacturers to do battery more big, use high capacity cell to satisfy the consumer to the interests demand of super long standby time.But jumbo battery has dangerous, insecure factor and exists, and may blast during its charging.
For these reasons, the double cell power supply plan has appearred on the market.The general supply power mode that adopts two batteries supply power mode simultaneously in parallel or adopt two battery series connection of present double cell power supply plan, when adopting two batteries parallel connection while supply power modes, if the voltage of two batteries is different, the connected mode of battery parallel connection can cause thermal losses in the internal resistance of battery, identical until two cell voltages, and the big electric current that produces in this case also has certain damage to battery; When adopting the supply power mode of two battery series connection, causing supply power voltage is original twice, and the operating voltage of peripheral devices, withstand voltage properties require all to change, and can't continue to use former device, have directly increased production cost.
Thereby existing technology is still waiting to improve and improve.
The utility model content
In view of above-mentioned condition, be necessary to provide a kind of electric weight that the standby for a long time of dull and stereotyped handheld device can be monitored two batteries again in real time that solves, in time switch the dull and stereotyped handheld device of supplying cell.
For solving the problems of the technologies described above, provide a kind of super long standby time double cell dull and stereotyped handheld device, comprise dull and stereotyped handheld device internal battery, leather sheath battery, commutation circuit control module peace wrench holding equipment operating voltage output interface, this flat board handheld device internal battery and leather sheath battery are respectively equipped with the battery output interface, this commutation circuit control module electrically connects with this battery output interface respectively, and this commutation circuit control module and this flat board handheld device operating voltage output interface electrically connect.
This leather sheath battery is circumscribed with solar energy photovoltaic panel, and this solar energy photovoltaic panel can be given this leather sheath battery charge.
Be electrically connected with the protective circuit module between this leather sheath battery and this solar energy photovoltaic panel.
This protective circuit module is located on this leather sheath battery.
The commutation circuit control module of the dull and stereotyped handheld device of the utility model super long standby time double cell can be monitored the output voltage values of two batteries in real time, and according to the variation automatic switchover supplying cell of cell output voltage value, realize that two batteries alternately are dull and stereotyped handheld device power supply, the external solar energy photovoltaic panel of this leather sheath battery, under the condition of solar irradiation abundance, photovoltaic panel can provide the charging current that continues 300mA, the user is when using internal battery, can utilize sunlight to give the leather sheath battery charge simultaneously, after the leather sheath battery is full of electricity, can power to main system simultaneously and also can charge to internal battery, the adding of heliotechnics allows charging break away from the restriction of power line, where walks where to be charged to.
