Terrain information can significantly impact load power demand, and in turn, on battery life and system efficiency of a hybrid energy storage system (ESS) with battery and supercapacitor. Taking terrain information ahead into consideration for proactive power management is one of the most important ways to improve battery life and overall system efficiency. However, since terrain information is typically...
Accurate and reliable prediction on power demand is critically important for effective power or energy management for hybrid energy storage systems with battery- super-capacitor for electric vehicles. Terrain information is one of the most common factors on power demand prediction from both driving and regenerative braking. This paper first establishes system dynamic models with battery, super-capacitor...
The energy storage system (ESS) is the heart of electric vehicles, which determines their efficiency, power, and driving range, etc. The emerging demand of modern electric vehicles often requires the ESS to preserve high energy density, along with the high peak power. Nowadays, batteries and supercapacitors, which could deliver high energy and power capability respectively, are commonly used as the...
