【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
