Provided is a system or method for a coolant flow into each of a plurality of energy storage devices (10) embedded in an electric vehicle. Each of the energy storage devices (10) includes a heat exchanger (11) thermally conductively connected with a segmented battery module (13). The segmented battery module (13) includes battery cells (13B) and sensors (13C, 13D, 13E). The heat exchanger (11) includes an HE flow controller (11C). Individual sensor information about each of the energy storage devices (10) is collected through a BMU (13A) of each segmented battery module (13). A charging SCC (22) calculates an HE flow rate of the coolant pumped through the heat exchanger (11) of each of the energy storage devices (10) to cool the battery cells (13B) of the energy storage devices (10), by using the individual sensor information. The coolant delivered to the heat exchangers (11) can be cooled by an outer cooling unit (21) of a power source (20) during each charging session.

    전기 자동차에 내장된 복수의 에너지 저장 장치들(10)의 각각으로의 개별화된 냉각제 흐름을 위한 시스템 또는 방법이 제공된다. 각각의 에너지 저장 장치(10)는 세그먼트된 배터리 모듈(13)과 열 전도성으로 접속된 열교환기(11)을 포함한다. 세그먼트된 배터리 모듈(13)은 배터리 셀들(13B)과 센서들(13C, 13D, 13E)을 포함한다. 열교환기(11)는 HE 유량 제어기(11C)를 포함한다. 각각의 에너지 저장 장치(10)에 대한 개별 센서 정보는 각각의 세그먼트된 배터리 모듈(13)의 BMU(13A)를 통해 수집된다. 충전 SCC(22)는, 이 개별 센서 정보를 사용하여, 에너지 저장 장치(10)의 배터리 셀들(13B)을 냉각하기 위해, 각 에너지 저장 장치(10) 의 열교환기(11)를 통해 펌핑되는 냉각제의 HE 유량을 계산한다. 열교환기들(11) 에 전달된 냉각제는 각 충전 세션 동안 전원(20)의 외부 냉각 유닛(21)에 의해 냉각된다.
