A hybrid power supply includes a first battery array, a second battery array, and a controller. The first battery array includes a plurality of first battery packs. The second battery array includes a plurality of second battery packs. The controller controls charging and discharging of the first battery array and the second battery array. The second battery array is connected in parallel with the first battery array by at least a bidirectional converter. The first battery array and the second battery array are connected to a power bus for outputting power. The first battery array has a high-rate charging/discharging performance higher than the second battery array. The second battery array has a capacity greater than the first battery array.
