The Battery Book for Drivers

Electric cars have changed the way drivers think about range, charging, cost, performance, and long-term ownership. At the centre of that change is the battery: the most important, most expensive, and most misunderstood part of the modern EV. The Battery Book for Drivers: Range, Charging, Degradation, Chemistry, and Everyday Myths is a clear, fact-based guide to how electric-vehicle batteries really work in daily life. Written for ordinary drivers rather than engineers, it explains usable capacity, state of charge, home charging, rapid charging, charging curves, cold-weather range loss, battery degradation, LFP and nickel-rich chemistries, warranties, used-EV battery health, recycling, safety, and the myths that surround electric motoring. This book avoids speculation and sales talk. Instead, it gives drivers a practical, readable understanding of what affects range, why batteries age, when 100 percent charging matters, why fast charging is useful but not magical, how temperature changes battery behaviour, and what buyers should check before purchasing a used EV. Whether you already own an electric car, are thinking of buying one, or simply want to understand the technology behind the shift away from combustion engines, this book offers a calm, accurate, and accessible guide to the battery beneath the floor.
