Since it is possible that the launch time might be postponed and the battery discharges for a longer time which it may lead to the decrease of EED bus voltage，it is necessary to evaluate the allowable minimum EED bus voltage.The explosion of an EED requires a current of no less than 5 A.From Table 3 which shows the allowable minimum EED bus voltage for each EED，we can see that the minimum battery voltage is 24 V.According to the fault countermeasure strategy during the powered-flight phase，the ultimate battery voltage is higher than 25 V.
