Description
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.
