Abstract

A BMS estimation method for battery system SOP with respect to peak and continuous power switching is disclosed, including implementing a method of obtaining the currently permissible sustained discharge power of a battery system, the current discharge power and the current allowable peak discharge power. As that current permissible peak discharge power is taken as the current SOP estimation result of the battery system and reported to the whole vehicle. An SOP estimation result of that battery system is determined according to the comparison result of the current discharge power of the battery and the current permissible sustained discharge power. The invention can avoid irreversible damage to the battery caused by continuous large current charging and discharging, and prolong the cycle life of the power battery.

Description

technical field [0001] The invention relates to the field of electric vehicle batteries, in particular to a method for estimating the SOP of a battery system by a BMS about switching between peak and continuous power. Background technique [0002] SOP (State of power) estimation is a key core algorithm of the battery management system and an indispensable part of vehicle energy management. Whether the estimation strategy is reasonable or not directly affects the power, comfort and economy of the vehicle . [0003] A reasonable SOP algorithm must monitor the current discharge state of the battery to estimate the current maximum discharge capacity of the battery. However, the common practice in the industry is to calibrate the peak discharge power of the battery within the corresponding pulse time as the benchmark for the SOP estimation of the battery management system, ignoring the continuous peak discharge power of the battery. The effect of power discharge on the battery. ...
