In order to overcome deficiencies of phenomenological models of batteries for electric vehicles, this paper analyses models based on electrochemical laws. Considering one space coordinate, there are essentially two approaches: (i) macrohomogeneous and (ii) single-pore models. It is shown that they are equivalent under general assumptions. A macrohomogeneous model of a valve-regulated lead/acid battery is calculated for a highly dynamic discharge current pattern. Simulated voltage as a function of time matches experimental results, but further work is necessary, especially in a careful determination of several empirical parameters. Finally, battery models restricted to ordinary differential equations are discussed as an approximation of spatial models
