Wireless Sensor Network Node Solar Energy Storage BatteryCharging and Discharging Protection Circuit
Battery is an important component of solar-powered devices.This design of the battery charge and discharge protection,the use of comparators,transistors,shunt-chip microcomputer or chip,reducing the energy consumption itself.In charging protection circuit to prevent recharging voltage,increasing the high voltage branch;in a discharge protection increase hysteresis circuit solve the general discharge protection caused by damage to the battery,oscillation to charge and discharge protection function more perfect.The experimental results show that the circuit is simple,and easy to operate,and charge and discharge protection movement accurate,reliable,and suitable for the maintenance of the inconvenience in remote wireless sensor network monitoring application.
