A lithium-ion battery pack for a vehicle comprises a first battery module, a second battery module, a heater, a first switch, a second switch, and a third switch. The first battery module is connected in parallel with the second battery module. The heater is electrically connected to the second battery module and is disposed close to the first battery module and heats the first battery module. The first switch switches a power supply from the first battery module leading outward to ON or OFF, and switches a power supply from the first battery module leading outward for engine start to ON. The second switch switches a power supply from the second battery module leading outward to ON or OFF. The third switch switches a power supply from the second battery module to the heater to ON or OFF, and switches a power supply to the heater to ON before the engine start.
