Programmable charge rates to support various modes, such as fast-charge and trickle-charge A solar charger is a charger that employs solar energy to supply electricity to devices or batteries.Buck-boost architecture charges the battery even when the voltage of the solar panel is below the battery voltage.Depending on the voltage of the solar array used, an optional DC/DC has been added to increase efficiency in higher voltage applications.
With the addition of MPPT firmware, the RL78/G14 can control the ISL81601 to maximize the efficiency of the solar panels.
Utilizing the benefits of the ISL81601 buck-boost controller, this design can be used to charge a wide array of battery voltages even if the solar panel is delivering an output voltage much lower than its nominal output. An RL78/G14 MCU is added to ensure that the battery is not overcharged and to monitor the status of the battery. Using a solar cell to charge a battery is a very popular application. However, solar cells also present challenges because of the wide variability of the output voltage, depending on the amount of solar energy directed at the panel, temperature, and the load on the panel.
