“…Depending on the required traction current and the flywheel speed, the rule-based operating mode was divided into 12 states which corresponded to either charging, discharging or speed maintenance of the flywheel. Itani et al [24,25] designed a flywheel/battery HESS with a special focus on the traction and regenerative braking strategy. The main electrical source was the battery, but it only contributed if the FESS could not absorb the whole regenerative braking or deliver the whole traction power.…”

Electrification of transportation is an effective way to tackle climate change. Public transportation, such as electric buses, operate on predetermined routes and offer quiet operation, zero local emissions and high energy efficiency. However, the batteries of these buses are expensive and wear out in use. The battery ageing is expedited by fast charging and power spikes during operation. The contribution of this paper is the reduction of the power spikes and thus a prolonged battery lifetime. A novel hybrid energy storage system for electric buses is proposed by introducing a flywheel in addition to the existing battery. A simulation model of the hybrid energy storage system is presented, including a battery ageing model to measure the battery lifetime. The bus was simulated during its daily driving operation on different routes with different energy management strategies and flywheel configurations. These different flywheels as well as the driving cycle had a significant impact on the battery life increase. The proposed hybrid battery/flywheel storage system resulted in a battery lifetime increase of 20 on average.

“…Permanent magnet synchronous motors (PMSMs) are frequently used in electric vehicles on account of their higher efficiency and torque density compared to other motors [5]. In addition, electric vehicles demonstrate higher energy efficiencies compared to vehicles powered by internal combustion engines owing to the fact that they can recover and use some of the energy wasted as frictional heat at the brake through use of regenerative braking and batteries during deceleration [6].…”

In general, electric vehicles have significantly different structures compared to vehicles running on internal combustion engines owing to their use of electric motors as the source of power and batteries as energy-storage devices. Electric vehicles also demonstrate different driving performance and dynamic characteristics, as they are capable of recovering some of the energy wasted in the form frictional heat at the brake through use of regenerative braking during deceleration. The proposed study discusses a mathematical model constructed by identifying characteristics of certain key components and the hybrid control unit (HCU) of an electric vehicle. Corresponding correlations among these components were analyzed. In addition, a dynamic model of the electric vehicle was designed using the model-based design approach in accordance with the standard V-Model development process ISO 26262-an international standard for automotive safety. All models discussed herein were developed using the MATLAB/SIMULINK package, and dynamic characteristics of the vehicle were analyzed through simulations.
