Embodiment Construction

[0040] Reference will be made in detail to embodiments of the invention, examples of which are illustrated in the accompanying drawings.

[0041] Figure 4 is a block diagram of the configuration of the storage battery pack according to the embodiment.

[0042] The battery pack 100 includes: a main battery 110 including a plurality of battery cells; a main relay unit 130 for controlling connection of the main battery 110; a control unit 200 for checking status information of the battery and controlling charging / discharging of the battery ; and a power conversion unit 120 for changing the level of the DC voltage.

[0043] One end of each main battery 110, the control unit 200, and the power conversion unit 120 are grounded. The power conversion unit 120 can be separated from the ground.

[0044] The power conversion unit 120 is connected to the sub storage battery and the 12V electric load 71 .

[0045] The control unit 200 performs operations of a conventional BMS, BDU, an...

Abstract

A battery pack includes a main battery including a plurality of battery cells, a power conversion unit configured to change a level of a voltage output from the main battery, a main relay unit disposed between the main battery and the power conversion unit, the main relay unit switching a connection between the main battery and the power conversion unit, and a control unit configured to monitor a state of the main battery and control operation of the power conversion unit, wherein the control unit includes units for measuring voltage, current and temperature values of the main battery and a unit for outputting a gate signal for controlling the operation of the power conversion unit.

Description

technical field [0001] The present invention relates to a battery pack as an energy storage device used in a hybrid vehicle, and more particularly to a battery pack including a high-capacity 48V battery. Background technique [0002] In general, having an internal combustion engine using gasoline or diesel as a main fuel causes pollution such as air pollution. Therefore, many efforts have been made recently to develop electric vehicles or hybrid vehicles to reduce pollution. [0003] An electric vehicle uses a battery motor that is operated by electrical energy output from a battery. Such an electric vehicle uses a battery pack in which a plurality of rechargeable secondary batteries are arranged into a single battery pack as a main power source, and produces no exhaust gas and generates very little noise. [0004] Hybrid vehicles use at least two sources of power, such as a built-in engine and battery-operated actuators. Compound hybrid vehicles are currently under devel...
