POWER UNIT
Document Type and Number:
Japanese Patent JP2023154277
Kind Code:
A
Abstract:
To disclose a technique of suppressing deterioration of estimation accuracy of a charging state of a battery while suppressing the increase of a size of a power unit.SOLUTION: A power unit comprises: a battery; a first rotational machine; a second rotational machine; a first inverter device connected to between the battery and the first rotational machine; a second inverter device connected to between the battery and the second rotational machine; a first angle sensor that detects a rotational angle of the first rotational machine; a second angle sensor that detects the rotational angle of the second rotational machine; a current sensor that detects a current value flowing in the battery; and a control device connected to the current sensor. The control device acquires a detection value by the current sensor when a difference between the rotational angle of the first rotational machine detected by the first angle sensor and the rotational angel of the second rotational machine detected by the second angle sensor is within a predetermined first reference range.SELECTED DRAWING: Figure 1
