Battery charge/discharge control apparatus

A battery charge/discharge control apparatus for a vehicle capable of driving an electric motor by a battery is provided. Temperature of the battery is detected, temperature history distribution of the battery after start of temperature detection is calculated, and a lifetime workload of the battery is calculated on the basis of this temperature history distribution of the battery. A permissible value of a workload increase rate indicating a workload to increase per unit distance is calculated on the basis of the lifetime workload of the battery and a travel distance of the vehicle. An actual workload increase rate of the battery is compared with the permissible value of the workload increase rate. In the case where the actual workload increase rate is larger than the permissible value of the workload increase rate, an output is restricted from the output of the battery restricted in a normal driving mode if necessary by a restricted value based upon a difference between the actual workload increase rate and the permissible value of the workload increase rate. This makes it possible to carry out lifetime prolonging control for the battery more accurately by setting up an appropriate charge/discharge permissible amount in accordance with temperature change of the battery in the past.
