Abstract: The charging device includes a BT first/second terminal, a PS first/second terminal, a first/second power line, a bypass power line, and an earth leakage detector. When the first/second power line is passing through and the sum of the currents flowing through the first/second power line is other than zero, the earth leakage detector interrupts the first/second power line. The bypass power line bypasses the earth leakage detector and connects the BT second terminal to the PS first terminal. The controller disconnects the power from the PS first (second) terminal. The controller connects a battery to the BT first (second) terminal and also connects the PS first terminal and the BT second terminal through the bypass power line. If the earth leakage detector is activated, the bypass power line will be disconnected. Then, charging of the battery is started.

Abstract: An overcurrent protection device includes a first input terminal, a second input terminal, a first output terminal, a second output terminal, a breaker, a current sensor, and a comparator. A positive terminal and a negative terminal of a power source are connected to the first input terminal and the second input terminal. The second output terminal is connected to the second input terminal. The breaker includes a switch connected between the first input terminal and the first output terminal and opening upon reception of an interrupt command signal. The current sensor measures a difference between a current flowing between the first input terminal and the first output terminal, and a current flowing between the second input terminal and the second output terminal. The comparator sends the interrupt command signal to the breaker when a measurement value of the current sensor exceeds a first current threshold value.

Abstract: Electrified vehicle includes a first motor, a battery for supplying power to the first motor, a first inverter for converting DC power from the battery into AC power supplied to the first motor, a charging inlet for receiving charging power for charging the battery, a charging circuit for connecting the charging inlet to the first inverter via a neutral point of the first motor, and a control device for controlling the operation of the first inverter. The charging circuit includes a charging smoothing capacitor provided between the charging inlet and the first motor. After the charging of the battery by the charging device is completed, the control device causes the first inverter to perform the boosting operation to discharge the charge accumulated in the charging smoothing capacitor from the first inverter to the battery side.

Abstract: An increase in noise can be suppressed. A motor control device includes N inverters configured to control N motors connected via power cables based on PWM signals, respectively, and a phase controller configured to determine phases of N carrier signals to be used for generating PWM signals to be supplied to the N inverters so that a sum of N vectors represented by noise amounts related to the respective N motors becomes zero.

Abstract: A data acquisition method of acquiring and latching data with a timing based on an input signal supplied to an input port, the method including: acquiring and retaining the data with a timing of when an edge of the input signal is detected, and starting a timer; and at the time of expiration of the timer, if the level of the input signal is a first level that is unchanged from start of the timer, latching the retained data and if the level of the input signal is a second level that is changed from the start of the timer, discarding the retained data.
