Abstract
A vehicle includes an engine, a first MG, a second MG, a PCU, a battery, and an EHC. The PCU is connected to the battery via a positive line and a negative line. The PCU is connected to the first MG via a 3-phase power line. The PCU is connected to the second MG via a 3-phase power line. The EHC has one end connected to a positive branch line branching off from a W-phase power line among the 3-phase power lines between the PCU and first MG. The EHC has the other end connected to a negative branch line branching off from a negative line between the PCU and battery.
