As one of preferred version, this lithium battery stand-by power supply comprises at least one charging module, and each charging module is independent of single lithium cell charging, and each charging module is parallel-connection structure and includes battery detection circuit; Charging module also is connected with and can distributes the charging current regulating circuit of each charging module charging current according to the quantity of effectively putting into battery.
As another preferred version, be serially connected with selector channel commutation circuit, battery detection circuit and circuit between described charging module and the charged lithium cells by the selector channel sequential control circuit, the battery detection circuit quantity that efficiency confirmed puts into charged lithium cells feeds back to the selector channel sequential control circuit, sequencing control selector channel, selector channel commutation circuit time segment is opened each rechargeable battery passage, and timesharing is charged to each battery.
Present technique can utilize USB, solar energy, the automobile batteries energy to power; to many groups lithium battery carry out safe and efficient charging, can be in charging process according to the quantity of the battery charging current that automatically adjust; with the protection charge power supply, reach automatic, intelligent, safe and efficient charging.Many group lithium batteries are as stand-by power supply, overcome the difference of electric weight between the battery by output control circuit, stablely give load altogether.Except that using new battery, can use also that various old lithium batteries utilize the battery that is about to lose as stand-by power supply again in the family, energy savings reduces environmental pollution.
Description of drawings
Fig. 1 is the structured flowchart of embodiment one of the present utility model.
Fig. 2 is the structured flowchart of embodiment two of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
As shown in Figure 1, be specific embodiment of the utility model one, comprise charging module (in comprise battery detection circuit), charging current regulating circuit, output control circuit and the load of short-circuit protection and current limliting module, each cascade.
When extraneous power supply interventional systems; short-circuit protection and current limliting circuit are regulated the total current that outputs to each charging module according to extraneous power supply maximum output current; to protect extraneous power supply operate as normal. comprise battery detection circuit in each charging module, the charging current that the charging current regulating circuit distributes each charging module according to the quantity of effectively putting into battery.For example protecting current limliting module output current is 500mA; battery detection circuit detects 4 required rechargeable batteries; it is 125mA to the charging current of battery that current regulating circuit is set each charging module; when finding that wherein 2 batteries are full of (3 and 4); the charging current of the charging module (1 and 2) that the automatic adjusting of charging current regulating circuit meeting is not full of is 250mA, realizes the highly effective and safe charging.The voltage that output control circuit partly comprises battery just detects and booster circuit, exports electric weight according to the reasonable distribution of how much carrying out of each cell voltage, and the stable supplying load is used.In output control circuit can according to the voltage of peripheral hardware what, regulate output voltage automatically, satisfy the demand of load.
As shown in Figure 2, be specific embodiment of the utility model two, adopt shunting mode that battery is charged, mainly adopt the mode of timesharing that battery is charged.It comprises short-circuit protection and current-limiting circuit, charging module, selector channel sequential control circuit, selector channel switching and battery detection circuit, each rechargeable battery, output control circuit and load.
When the power supply connecting system, short-circuit protection and current limliting circuit are regulated the total current that outputs to each charging module according to extraneous power supply maximum output current, to protect extraneous power supply operate as normal.The battery detection circuit quantity that efficiency confirmed puts into rechargeable battery feeds back to the selector channel sequential control circuit, and selector channel sequential control circuit time segment is opened each rechargeable battery passage, and timesharing is charged to each battery.For example protecting current limliting module output current is 500mA; battery detection circuit detects 4 required rechargeable batteries; the selector channel sequential control circuit can be at a fixed time in respectively with this passage of opening each rechargeable battery (as in first 1 minute of beginning, making the switch of rechargeable battery 1; battery 1 is charged; its charging current is 500mA, and other passage disconnects during this period.At second switch of making rechargeable battery 2 in 1 minute, battery 2 to be charged, its charging current is 500mA, other passage disconnects during this period.Open channel 3 and channel 4 and a circulation passage 1 by that analogy).The charging of realization highly effective and safe.The voltage that output control circuit partly comprises battery just detects and booster circuit, the reasonable distribution of how much carrying out according to each cell voltage is exported electric weight, the stable supplying load is used, in output control circuit can according to the voltage of peripheral hardware what, automatically regulate output voltage, satisfy the demand of load.
