Test equipment for a battery management system is provided. A battery-parameter recognition module measures a standard battery to obtain the first correction input, and uses the capacity test formula and the relaxation time test formula to perform a first charge and discharge test on the battery to be tested to obtain first battery parameter. A real-time simulation module determines the battery model and the simulated battery state based on the first battery parameter and the dynamic load. Each simulator of a physical signal simulation module provides a battery physical signal indicating the battery model. A connector provides the battery physical signal to the battery management controller under test. The battery management controller under test provides a stimulated battery state based on the battery physical signal. Master equipment compares the simulated battery state with an estimated battery state to determine whether the battery management controller under test is normal.

An output control apparatus of a motor includes a controller formed by having a power device to bridge a motor and a power supply. The controller incorporating the power device provides voltage control modulation during different motor speeds so as to fix the recharging voltage at the DC bus in a specific range without involvement of any voltage converter. It is unnecessary to use additional complex circuits or other DC/DC converters to reduce the voltage recharged from the motor running at a high speed. In addition, space for the apparatus is reduced, and the specification and function of the original controller can be maintained without trading off work in redesigning the motor system.
