Abstract：
 The invention is a kind of online updating method for accumulator charge state- output voltage character curve and the self-adaptive power distribution control technology field in compound dynamic system. The character lies in: it determines the power Pb should by outputted by the accumulator according to the compound dynamic system power distribution tactics when the car is in stable state, and finds out the accumulator charge state-output voltage character curve C1 under the power, and the output voltage Ua of current SOC accumulator on the curve, and adjusts the output voltage of the accumulator, thus the output power of the accumulator can reach Pb; then acquires the voltage Ub of current accumulator state, updates and acquires the new voltage U according to formula : Uc = ¦ÁUa+(1-¦Á)Ub, increased the voltage for Uc_Ua on the curve C1, thus completes the updating. The method can avoid the error caused by accumulator temperature and aging factors.
