In "Electric Vehicle Battery Systems", there is no information on the author's, Sandeep Dhameja's, education. His occupation at the time of publication (2002) seems to be in the field of business consulting. That his education, if any, is not in a technical field at all, becomes credible when reading statements like "... specific power greater than 200 Whr/kg" (p. 13), or "Specific Power: 150-200 Wh/L" (p. 44). Standard (SI) units are used in confusing mixture with non-standard units, even in the same equation, like: "Electrode size: 14.7cm x 29.7cm = 67.7in2" (p. 42). Language usage is poor and the book does not seem to have been proofread. Almost all the discussion in the book refers either explicitly or implicitly to two battery technologies that are outdated for EV energy storage purposes: valve-regulated lead-acid (VRLA), and NiMH. Li-ion, which has currently taken over in the industry as a vastly superior technology, is mentioned mainly as a "promising future technology", which, of course, was more or less true in 2002. I give the book one star because in all this desert, there is the occasional cactus of useful information. Regardless of the time factor, Butterworth-Heinemann should be ashamed of themselves for this publication.
