Abstract: In order to improve the rapidity of battery charging and prolong the service life of the battery, a photovoltaic controller based on MSP430 was designed. In view of the problem that traditional methods cant achieve the battery power supply stably, a kind of intelligent charging photovoltaic controller based on SQP was put forward. The method can calculate the maximum power point of PV modules fast and accurately to improve the stability of the output of photovoltaic modules, which can improve the efficiency of battery charging effectively. Through the analysis of the model characteristics of photovoltaic cells, a threestage charging control strategy was explored, and the SQP optimizing method was used in MPPT control, the results of the simulation prove the quickness and accuracy of the algorithm.
