Abstract: Provided are a computer program, a determination device, and a determination method. A computer is caused to execute a process of estimating a state of at least one of an energy storage device and a charge system by executing a simulation using a battery model for simulating the energy storage device and a charge system model for simulating the charge system that charges the energy storage device and determining the compatibility between the energy storage device and the charge system based on the estimated state.
