低溫BMS系統(tǒng)剩余充電時間預估的研究

打開文本圖片集

【摘  要】當前新能源汽車大規(guī)模使用，充電時間過長是影響車主使用的主要問題，而剩余充電時間預估不準又給車主帶來另外的煩惱，特別是低溫狀態(tài)下充電預估時間，因低溫加熱影響又增加了預估時間難度。本文介紹一種低溫BMS系統(tǒng)剩余充電時間預估的策略，并結合真實的充電柜和溫度箱進行驗證。

【關鍵詞】BMS系統(tǒng);充電時間;低溫

【Abstract】At present，new energy vehicles are used on a large scale，and the long charging time is a problem that mainly affects the use of car owners，and the inaccurate estimation of the remaining charging time brings another trouble to car owners. In particular，the estimated time of charging under low temperature conditions has increased the difficulty of estimating time due to the influence of low-temperature heating. This article introduces a strategy for estimating the remaining charging time of a low-temperature BMS system，and verifies it with a real charging cabinet and temperature box.

【Key words】BMS system;charging time;low temperature
