Rule-Based Control of Battery External Heating for Electric Vehicle During Driving at Low Temperatures

As the only power source of pure electric vehicles, lithium-ion batteries play an important role in vehicle powertrain systems. However, lithium-ion batteries have a significant reduction in capacity and power capability at low temperatures, which results in a greatly shortened driving range and poo...
