Charging, so as to ensure the uniformity of battery electric quantity and simple in construction, cost is low, efficiency high.
Its technical scheme is such：Solar telephone battery equalization system, it include solar components and with it is described too
The MPPT controller that positive energy component electricly connects, it is characterised in that：The MPPT controller has also electricly connected inverse-excitation type charging
Circuit, the inverse-excitation type charging circuit are connected with battery, and the battery has electricly connected balance controller, the MPPT controller
Also it is connected by switching with the battery, the switch electricly connects with the balance controller.
It is further characterized by：
The inverse-excitation type charging circuit includes high frequency transformer, and the primary side of the high frequency transformer is opened by FET MOSFET
Pass is electricly connected with the MPPT controller, and one end of the secondary of the high frequency transformer is connected by switch and the GND
Connect, the other end of the secondary of the high frequency transformer is connected by diode with the anode；
The balance controller includes monomer voltage sampling A/D chip, and the monomer voltage sampling A/D chip passes through Serial Peripheral Interface (SPI)
SPI electricly connects with micro-control unit MCU, and the monomer voltage sampling A/D chip is connected with the anode；The field effect
Should pipe switch mosfet cut-off frequency by the balance controller output pwm control signal be adjusted.
After employing such structure, when larger difference occurs in cell voltage, reverse excitation circuit is switched on to low-voltage
Battery is charged, and until all cell voltages do not have larger difference, avoid influences making for battery because of battery consistency difference
With the life-span, simple to operate, cost is low, and high without coulombic efficiency caused by loss generating.
