چکیده
<div class="section abstract"><div class="htmlview paragraph">Rapid adoption of battery electric vehicles means improving the energy consumption and efficiency these new is a top priority. One method accomplishing this regenerative braking, which converts kinetic to electrical stored in pack while vehicle decelerating. Coasting an alternative strategy that minimizes by decelerating using only road load. A model refined assess coasting, other deceleration strategies. load based on public test data calculates tractive effort requirements speed acceleration. Bidirectional Willans lines are basis powertrain simulating consumption. Vehicle power modeled backward from prescribed linear velocity curves, coasting trajectory forward given zero power. Decel modes motor also modeled. Multi-mode decel (using low mode with braking) presented as set intermediate An example strategies fixed-route simulations, scoring travel time, consumption, bias towards minimizing one those metrics. Regenerative braking has lowest but such increases overall cost. lower cost balancing reductions time Model sensitivity grade accessory fluctuation makes it adaptable different environments. Simulation results demonstrate how regen alternatives could be enhance connected automated systems vehicles.</div></div>

Energy Management Strategies for Plug-In Hybrid Electric Vehicles
Plug-in hybrid electric vehicles (PHEVs) differ from hybrid vehicles (HEVs) with their ability to use off-board electricity generation to recharge their energy storage systems. In addition to possessing charge-sustaining HEV operation capability, PHEVs use the stored electrical energy during a charge-depleting operating period to displace a significant amount of petroleum consumption. The parti...

Power management strategies play a key role in the design process of hybrid electric vehicles. Electric Assist Control Strategy (EACS) is one of the popular power management strategies for hybrid electric vehicles (HEVs). The present investigation proposes a new framework to advance the EACS. Dynamic Programming method is applied to an HEV model in several drive cycles, and as a result, some op...
متن کاملSignificant Characteristics of Multi Carrier Energy Networks for Integration of Plug-In Electric Vehicles to Electric Distribution Network
One of the big concerns of big cities is facing with the increase of fossil fuel vehicles in the roads. The cars intensify greenhouse gas emission in civic centers. One approach to reduce the emission is replacing the cars by Plug-In Electric Vehicles (PEVs). In spite of reducing the emission, PEVs have some adverse effect on electric distribution networks. Technical challenges such as load and...
