Vehicle to Load (V2L) Scalable Architecture with On-Board Smart Power Panel Technology

Abstract

<div class="section abstract"><div class="htmlview paragraph">Modern automotive industry field is recently moving to more electrification level, so the presence of Battery Electric Vehicles (BEVs) is constantly increasing, along with charging technology evolution.</div><div class="htmlview paragraph">Typically, BEVs do not use a significant portion of their battery’s capacity in day-to-day travel, which means their most valuable asset, the battery, sits idle during most of its life. Vehicle to Load (V2L) feature enables the transfer of energy from vehicle to the external loads (like utility tools, dryer, camping equipment or any other electrical appliance) which is connected to the power socket present in the Power Panel to perform AC Discharging. V2L technology lets consumers get more energy from a vehicle, even when it is turned off, improving consumer appeal. Bottomline, consumers can use this on-board Power Panel like a normal portable generator.</div><div class="htmlview paragraph">More specifically, this paper will explore a scalable V2L architecture design with on-board Smart Power Panel technology, requested to support multiple vehicle platforms across all segments, spanning from passenger cars up to Light Commercial Vehicles (LCVs), having the following innovative capabilities:<ul class="list disc"><li class="list-item"><div class="htmlview paragraph">Usage of on-board equipment, natively designed with the rest of vehicle electronics design (thus, reaching better functional safety performance)</div></li><li class="list-item"><div class="htmlview paragraph">Leverage of existing bi-directional On-board Charger component, thus optimizing total cost</div></li><li class="list-item"><div class="htmlview paragraph">No need of dedicated circuit breakers or Ground Fault Circuit Interrupt (GFCI), increasing customer convenience</div></li></ul></div><div class="htmlview paragraph">Moreover, this paper will also describe the operational control logic and HMI interface of such a V2L On-board Power Panel system, covering a wide technology scope (BEV, PHEV and REEV propulsion systems).</div></div>
