post. Mathematical modeling work by Pesaran et al.14 shows that the 2001 model Ni/MH module in the Toyota Prius suffered from a non-uniform temperature distribution while the 2004 model, that used two connections for each grid, had a nearly uniform temperature distribution (Fig. 2). The model results were verified by thermal imaging experiments.
