The invention discloses a charger circuit system, which comprises power generation equipment, a full-wave bridge rectifier, a unidirectional silicon controlled rectifier, a sub-sampling integrated circuit detection module and a lithium battery pack, wherein the power generation equipment is connected with the alternating current input end of the full-wave bridge rectifier through an output circuit, and the positive output end and the negative output end of the full-wave bridge rectifier are correspondingly connected with the anode and the cathode of the unidirectional silicon controlled rectifier respectively. According to the charger circuit system, the power generation equipment, the full-wave bridge rectifier, the unidirectional silicon controlled rectifier, the sub-sampling integratedcircuit detection module and the lithium battery pack are matched for use, the sub-sampling integrated circuit detection module controls whether the lithium battery pack is charged or not, and the lithium battery pack is effectively prevented from being overcharged. Meanwhile, the full-wave bridge rectifier and the unidirectional silicon controlled rectifier can be used for rectifying, filtering and discharging unstable alternating current generated by power generation equipment, so that the voltage fluctuation is reduced, the lithium battery pack is protected, and the service life of the lithium battery pack is prolonged.
