The invention relates to a heavy truck new energy automobile power battery control system which comprises a feedback control stable input circuit, a passive controller control circuit and an output power control circuit. According to the heavy truck new energy automobile power battery control system and the feedback control stable input circuit, the purpose of reducing circuit noise and interference is achieved by improving the stability of the magnification times, the decline degree of the magnification times of a low-frequency area and a high-frequency area is reduced, and therefore the transmission band is broadened by about 1+AF times, and the stability of output voltage is improved. The passive controller control circuit reduces the self consumption of the circuit by controlling a flowing signal, and ensures that more limited electric quantity of the power battery can be provided for a load. The output power control circuit can keep the total output power of the power amplifier unchanged, the corresponding relation between the load impedance change and the output power is weakened, and the power control of the power battery is more accurate.
