摘要： The boost converter control device includes a plurality of boost converters connected in parallel to each other with respect to the secondary batteries, and an ECU (control unit) that controls each of the plurality of boost converters. When warm-up of the secondary battery is required, ECU performs a first control for adjusting the phases of the plurality of boost converters to be in phase with each other in response to the current value flowing through the secondary battery becoming larger than a predetermined threshold, and performs a second control for stopping the operation of a part of the plurality of boost converters in response to the current value flowing through the secondary battery becoming equal to or smaller than the predetermined threshold.

摘要： A vehicle including a traction battery pack, a conduit system, a sensor, an emitter, and a control system is provided. The conduit system may provide a path for coolant to enter and exit the pack and includes a conduit. The sensor may measure conditions of the pack and conduit system. The emitter may be arranged with the conduit to form a peristaltic pump. The control system may activate the pump based on sensor signals to adjust a conduit portion to influence a flow rate of the coolant flowing therethrough. The emitter may be an electromagnet to output a magnetic field. The emitter may be a voltage emitter or electric field emitter. The sensor may measure a flow rate of at least a portion of the conduit system or a temperature of the pack.
