Problems solved by technology

[0006] Accordingly, in the conventional vehicle battery management scheme, since the information for the management of the battery is collected in a state where the battery and other components are electrically connected, there is a problem in this state that due to other components Impact on collected information, the state of the battery is not accurately monitored, or during monitoring of the battery, power is supplied to other controllers that do not need to operate, causing unnecessary power loss

Abstract

The invention relates to a system and a method for managing a battery of a vehicle. A battery management system of a vehicle includes a first controller configured to control a power-on (IG ON) state and a power-off (IG OFF) state of a plurality of controllers, and a second controller including a real-time clock (RTC) and configured to control the power-on (IG ON) state and the power-off (IG OFF) state of the plurality of controllers when the power-off state is turned on by the first controller. And a monitoring unit that is awakened by receiving power directly from the sub-battery at intervals of a preset time calculated based on a count value provided from the RTC within a preset reference time period, and monitors states of the main battery and the sub-battery.

Description

technical field [0001] The present invention relates to a system and a method for managing a battery of a vehicle, and more particularly, to a system and a method for managing a battery of a vehicle which, after the vehicle stops running, in a power-off state, preliminarily pass each This controller effectively monitors the state of the battery to prevent various problems that occur when the battery is in a power-off state. Background technique [0002] In general, an eco-friendly vehicle powered by electricity generates power by driving a motor as an electric rotation device using electricity stored in a battery. The dynamic performance of environmentally friendly vehicles is closely related to battery performance, so effective monitoring and management of batteries is necessary. [0003] Generally, batteries of environmentally friendly vehicles are managed by a controller collectively called a battery management system (Battery Management System, BMS). The BMS collects v...
