The present disclosure relates to a battery capacity active estimation method for an electric vehicle. The method is capable of determining the battery capacity based on estimating a State Of Charge (SOC) of the battery before and after a discharge operation but without having to wait until an establishment of sufficient thermal and electric equilibria in the battery. The estimation of SOC may even be made while the battery is being slowly charged. Depending on the equilibrium state of the battery, SOCs may be either directly obtained by measuring Open Circuit Voltage of the battery when the battery is in electric equilibrium or calculated and estimated when the battery is not in electric equilibrium.

Battery capacity active estimation method used for electric vehicle

A preparation method of a three-dimensional nanosized porous metal oxide electrode material of lithium ion battery, which soaks a dried polymer colloidal crystal microsphere template in a metal salt solution as a precursor solution for a period of time, and obtains a precursor template complex after filtration and drying; heats the precursor template complex to a certain temperature at a low heating rate and keeps the temperature, and then obtains the three-dimensional nanosized porous metal oxide electrode material of lithium ion battery after cooling to room temperature. A metal oxide electrode material is manufactured, with the three-dimensional nanosized porous metal oxide electrode material thereby improving the ionic conductivity of the negative electrode material of lithium ion battery, and shortens the diffusion path of the lithium ions during an electrochemical reaction process, and improves the rate discharge performance of lithium ion battery greatly.
