A hybrid electric vehicle (HEV) includes: a battery, a hybrid starter generator (HSG) starting an engine, and a controller that identifies a state of charge (SOC) of the battery upon when a reverse gear input is detected, determines whether to charge the battery by the HSG based on the identified SOC of the battery. In particular, the controller controls battery charging in a charging control mode based on a SOC level of the battery when it is determined that the HSG needs to charge the battery.

Hybrid electric vehicle and charge control method therefor

A system for managing a battery of a vehicle may include: a temperature sensor measuring temperature of external air; an electric device cooler including an electric device mounted in the vehicle, an electric device cooling pipe through which cooling water for cooling the electric device flows, and a first pump circulating the cooling water; a battery cooler including a battery and a battery cooling pipe through which the cooling water for cooling the battery flows; one or more 3-way valves connecting or disconnecting the electric device cooling pipe to or from the battery cooling pipe; and a controller configured to control the first pump and the one or more 3-way valves to move the cooling water in the battery cooling pipe to the electric device cooling pipe when the measured temperature of the external air is the predetermined temperature or less.

System and method of managing battery of vehicle

A method and a system for diagnosing insufficiency of vehicle coolant includes a preparing step of checking whether the vehicle is in a stop state and is on flat ground. An operating step applies a predefined output to a coolant water pump when the vehicle is in the stop state and is on flat ground. A measuring step measures a rotation speed of an impeller of the coolant water pump for a period in which the predefined output is applied to the coolant water pump. A M determining step compares the measured rotation speed of the impeller of the coolant water pump with a reference speed to determine whether or not the coolant is insufficient.
