Using batteries after their first life in an Electric Vehicle (EV) represents opportunity to reduce the environmental impact and increase economic benefits before recycling battery. Many different second applications have been proposed, each with multiple criteria that be taken into consideration when deciding most suitable course of action. In this article, a battery assessment procedure is pr...

Battery management systems (BMS) are important for ensuring the safety, efficiency and reliability of a battery pack. Estimating internal equivalent circuit model (ECM) parameters battery, such as open voltage, resistance relaxation parameters, is crucial requirement in BMSs. Numerous approaches to estimating ECM have been reported literature. However, existing consider identification joint est...

Estimating the remaining energy in high-capacity electric vehicle batteries is essential to safe and efficient operation. Accurate estimation remains a major challenge, however, because battery state cannot be observed directly. In this paper, we demonstrate a method for estimating battery remaining energy using real data collected from the Charge Car electric vehicle. This new method relies on...

Abstract: This paper presents an on-board vehicular battery charger that integrates bidirectional AC/DC converter and DC/DC converter to achieve high power density for application in electric vehicles (EVs). The integrated charger is able to transfer electrical energy between the battery pack and the electric traction system and to function as an AC/DC battery charger. The integrated charger to...

Generation Batteries to Make a Practical Electric Semi Truck There is enormous interest around the development of an electric semi truck, and in order to understand the practical limitations imposed by the battery pack, a rigorous and thorough analysis considering battery metrics as well as vehicle design parameters is required. In this study, we find that an electric semi truck, such as the en...

The anode state of charge (SOC) and degradation information pertaining to lithium-ion batteries (LIBs) is crucial for understanding battery over time. This about each cell in a pack can help prolong the pack’s life cycle. Because limited observability, estimating capacity fade difficult. task even more challenging cells pack, as current through individual not constant when are connected paralle...

It is often challenging to manage the battery supply when dealing with a fleet of mobile robots during long experiments. If one uses classical recharge stations, then agents are immobilized during the whole recharge process. In this study, we present a novel approach that employs a battery pack swapping station. Batteries are charged in a rotating barrel, and the robots dock only for the time o...

Li-ion cell thermal-runaway failures can occur due to poor cell or battery-pack design (electrochemical or mechanical), manufacturing flaws, external abuse, and poor charger or system design. Fortunately, a procedure for detecting future failures shows promise. Internal cell faults continue to lead to thermal runaway failures in Li-ion battery packs used in the field. Though these events are ra...
