Solar recharging way circuit embodiment as shown in Figure 3:
Select the solar panel of 9V as generating element in this system, by L7805CV chip after solar power generation
After pressure stabilizing, by the voltage after power generation surely in 5V, then, charge and discharge are being carried out to lithium battery by TP4056 module, because lithium is electric
The voltage in pond is 3.7V-4.2V, and wireless module, and the circuits such as single-chip microcontroller are 5V power supply, so boosting power supply to the device.
TP4056 lithium battery charging circuit
Lithium battery charging circuit schematic diagram as shown in Figure 4, in the utility model, TP4056 module is used for lithium battery
Charge and discharge linearly.Mainly use constant current and voltage.Good thermal diffusivity also makes TP4056 ideal application in each
Kind portable device.
Its working principle is that battery starts to charge when chip input voltage is higher than the low voltage test thresholding of power supply.When
When cell voltage is less than 3V, battery will be with low current charge.When cell voltage is greater than 3V, battery is filled with constant-current mode
Electricity.When cell voltage is close to 4.2V, it is gradually reduced charging current, TP4056 enters constant-voltage charge mode.When charging current drops
Charging terminates when terminating threshold value to charging.
DC-DC booster circuit
DC-DC booster circuit connection figure as shown in Figure 5 selects DC-DC boost module to realize in the utility model
The boosting of 3.7V lithium battery, voltage becomes 5V after boosting, gives design power supply.
