Original Abstract Submitted
An estimation system includes a battery, an inverter, a motor, a U-phase current sensor, and an ECU. The inverter includes U-phase upper and lower arm circuits, V-phase upper and lower arm circuits, and W-phase upper and lower arm circuits. A mode of the inverter includes a first mode in which the U-phase upper arm circuit, the V-phase lower arm circuit, and the W-phase lower arm circuit are on and a second mode in which the U-phase lower arm circuit, the V-phase upper arm circuit, and the W-phase upper arm circuit are on. The ECU performs estimation processing for estimating a current value of the battery. The estimation processing includes first processing for estimating the current value in accordance with a detection value from the U-phase current sensor when the mode of the inverter is set to the first mode or the second mode.
