Abstract

A battery system comprises a battery comprising a plurality of battery modules, each battery module comprising at least one battery cell, a plurality of measuring units, each comprising a plurality of primary analog front end AFE modules connected in series and a secondary analog front end AFE module connected to one of the primary AFE modules in the series, a processor for processing data received from the measuring units and an isolator for providing electrical isolation between the measuring units and the processor, wherein the isolator is connected to one of the secondary AFE modules other than to the secondary AFE module that is connected to the primary AFE module that corresponds to an outermost battery module at the highest or lowest potential end of the battery. The battery system allows for a reduction in the withstand voltage of the isolator.

Description

technical field [0001] The technology of the present disclosure relates to a battery system and an energy storage system including the battery system. Background technique [0002] Recently, batteries have become widely used in various fields including portable devices such as mobile phones and notebook computers and large products such as electric vehicles and energy storage systems. A battery and a control circuit for controlling charging and discharging of the battery are generally included in a single system, and effective and efficient power control and management of the system becomes important. In particular, larger battery systems are particularly problematic because these systems can require control circuits to withstand larger voltages. Contents of the invention [0003] One inventive aspect is a battery system including a battery pack having a plurality of battery modules, wherein each battery module includes at least one battery cell. The battery system also ...
