And (3) charging:
the energy storage module of the mobile power supply comprises a plurality of parallel energy storage branches with control switches; each energy storage branch is provided with an independent voltage detection circuit; a controller is arranged in the mobile power supply; the voltage detection circuits are connected with the controller, and the control switches are controlled by the controller; (the control switch is a triode, a power MOS tube or a relay normally open/normally closed switch.)
During charging, the controller can control only one energy storage branch to be conducted, and the charging circuit charges the energy storage module in the energy storage branch; or the controller can control the conduction of a plurality of or all energy storage branches, and the charging circuit charges the energy storage modules in the conduction energy storage branches.
When discharging, the following steps are carried out: the controller can control only one energy storage branch to be conducted, and the energy storage modules in the energy storage branch are discharged through the output circuit; or the controller can control the conduction of a plurality of or all energy storage branches, and the conduction of the plurality of energy storage branches discharges through the output circuit.

step 1: judging whether partition charging is needed or not; if necessary, turning to step 2, otherwise, closing the switches K1 and K2, charging the energy storage modules in the 2 energy storage branches, and returning to step 1 after charging is completed;
step 2: selecting an energy storage module needing to be charged with priority;
step 3: charging an energy storage module which needs to be charged with priority;
if the energy storage module is full, or the voltage of the energy storage module reaches a preset value (such as a voltage value capable of starting an automobile), the priority charging is finished;
step 4: returning to the step 1;
if the voltage difference between the two energy storage modules is lower, for example, the voltage difference is more than 0.5v, before the 2 energy storage modules are charged simultaneously, a part of electricity needs to be charged first by the energy storage module with lower voltage, so that the voltages of the 2 energy storage modules are basically the same and then charged simultaneously.
During charging, one energy storage module can be filled firstly through switch control, then the energy storage module is disconnected, and the other energy storage module is connected for charging until the other energy storage module is also filled, so that the 2 energy storage modules are fully charged.
In step 1, a judging method of whether partition charging is needed is as follows:
(1) If all voltages of one energy storage module are lower than a preset value or the voltages of all the energy storage modules are lower than a preset value (such as lower than 3.2V), a preset function is required to be started (the preset function comprises starting an automobile (used as an automobile starting power supply) or charging a mobile phone and the like is required to be charged in a partition mode);
or, (2) pressing a manual priority charging button on the mobile power supply, and then starting partition charging.
In step 2, the method for selecting the energy storage module requiring the preferential charging is as follows:
generally, the energy storage module which is preferably charged is determined according to the voltage value and the capacity of the energy storage module; specifically, for the purpose of achieving the fastest charging to a preset value, the energy storage module with the highest voltage and the smallest capacity is preferably charged, and the most scientific method is as follows: firstly, calculating a charging quantity to determine an energy storage module needing to be charged with priority, wherein the charging quantity refers to a difference value between the nominal capacity of the energy storage module and the current electricity storage quantity; selecting an energy storage module with smaller charge amount as an energy storage module needing to be charged with priority;
if the A energy storage module can be filled when the A energy storage module is still required to be charged with 1000mA, and the B energy storage module can be filled when the B energy storage module is still required to be charged with 1200mA, the A energy storage module is selected as the energy storage module which is preferably charged.
The capacity of 2 energy storage modules may be equal or half of one another, in which case the smaller capacity energy storage modules are generally easier to fill.
If the voltage difference between the two energy storage modules is lower, for example, the voltage difference is more than 0.5v, before the 2 energy storage modules are charged simultaneously, a part of electricity needs to be charged first by the energy storage module with lower voltage, so that the voltages of the 2 energy storage modules are basically the same and then charged simultaneously.
During charging, one energy storage module can be filled firstly through switch control, then the energy storage module is disconnected, and the other energy storage module is connected for charging until the other energy storage module is also filled, so that the 2 energy storage modules are fully charged.

The energy storage module comprises a first energy storage module and a second energy storage module; the switching of the second energy storage module is carried out through the electronic switch, and when the automobile needs to be started in an emergency (namely when the charging of the power generation device is detected), the electronic switch is firstly disconnected, so that the first energy storage module is ensured to be fully charged; when the mains supply is used for normal charging of the mobile power supply, the electronic switch is closed, so that the whole battery is full, and the intelligent charging is embodied.
In a word, the partition charging type mobile power supply has the advantages of compact structure, easiness in implementation, flexibility and convenience in use, and capability of charging the mobile power supply through the built-in generator when external power supply is lacked.

In addition, with the BAT54CW schottky barrier diode, the forward voltage drop (both the forward turn-on threshold voltage and the forward voltage drop are lower (about 0.2V lower) than the PN junction diode because the schottky barrier height is lower than the PN junction barrier height), and since SBD (schottky barrier diode) is a majority carrier conduction device, there are no minority carrier lifetime and reverse recovery problems. The reverse recovery time of the SBD is just the charge and discharge time of the Schottky barrier capacitor and is completely different from the reverse recovery time of the PN junction diode. Since the reverse recovery charge of the SBD is very small, the switching speed is very high, and the switching loss is very small, which is especially suitable for high frequency applications. The structure and characteristics of SBD make it suitable for use as high frequency rectification in low voltage, high current output applications.
Furthermore, the ME6119A33PG type voltage stabilizer adopted by the voltage stabilizer is a high-hand LDO voltage stabilizer (400 mA Adjustable Voltage High Speed LDO Regulators) with adjustable input voltage, the output voltage is accurate, and the input voltage range is 2.5-18V; the application is particularly suitable here, not only for charging the energy storage module by means of a voltage booster circuit, but also as a reference voltage for use in a temperature detection circuit.
Therefore, the dual-input power supply circuit for the mobile power supply can be compatible with a wide range of input voltage, is wide in application, can be charged without alternating current, and is stable in circuit operation and high in practicability.
The LED driving circuit adopts a switching device (MOS tube) to control the on and off of the LED illuminating lamp, has small energy consumption, adopts a compact double-color LED lamp as a red-green indicating lamp, has compact structure and small occupied space, and in addition, the power supply circuit can provide stable 3.3V direct current voltage, can ensure the stable work of the LED lamp, has uniform light emission and avoids the brightness change and flickering of light. Therefore, the LED driving circuit is simple in circuit, few in used elements and easy to control.
The relay driving circuit adopts 2 parallel driving modules to drive the relay, and has high reliability and high safety, in addition, each driving module also has 2N-MOS tubes, namely, a redundant design is adopted, the time lag is small when switching, and even if one switching device is damaged, the relay can still work normally, so that the reliability is high, and the normal discharge of an automobile starting power supply can be ensured.
The detection circuit of the starting power supply adopts the A/D converter with multiple input channels to detect multiple paths of voltage signals, can realize temperature monitoring so as to realize overheat protection later, has high integration level, simple circuit, easy implementation and high detection precision, and can provide technical guarantee for the safe work of the starting power supply of the automobile.
