TL;DR: In this paper, a method for indicating state of charge of a battery being charged by a charger is presented, which includes: supplying a charging current from a battery charger to a battery pack, determining voltage of battery cells residing in the battery pack; and illuminating a visual indicator on the battery charger.
Abstract: A method is provided for indicating state of charge of a battery being charged by a charger. The method includes: supplying a charging current from a battery charger to a battery pack; determining voltage of battery cells residing in the battery pack; and illuminating a visual indicator on the battery charger to indicate state of charge of the battery pack, where brightness of the visual indicator correlates to the voltage of the battery cells in the battery pack.

TL;DR: A comparative study performed in order to select the most suitable control strategy for high-power electric vehicles powered by FC, battery and supercapacitor (SC), in which each energy source uses a DC/DC converter to control the source power and adapt the output voltage to the common DC bus voltage.
Abstract: Problems relating to oil supply, pollution, and green house effects justify the need for developing of new technologies for transportation as a replacement for the actual technology based on internal combustion engines (ICE) Fuel cells (FCs) are seen as the best future replacement for ICE in transportation applications because they operate more efficiently and with lower emissions This paper presents a comparative study performed in order to select the most suitable control strategy for high-power electric vehicles powered by FC, battery and supercapacitor (SC), in which each energy source uses a DC/DC converter to control the source power and adapt the output voltage to the common DC bus voltage, from where the vehicle loads are supplied Five different controls are described for this kind of hybrid vehicles: a basic control based on three operation modes of the hybrid vehicle depending on the state of charge (SOC) of the battery (operation mode control); a control strategy based on control loops connected in cascade, whose aim is to control the battery and SC SOC (cascade control); a control based on the technique of equivalent fuel consumption, called equivalent consumption minimization strategy (ECMS); and two based on control techniques very used nowadays, the first one of them is a fuzzy logic control and the second one is a predictive control These control strategies are tested and compared by applying them to a real urban street railway The simulation results reflect the optimal performance of the presented control strategies and allow selecting the best option for being used in this type of high-power electric vehicles

TL;DR: A stochastic fuzzy neural network (SFNN) instead of the traditional neural network that has filtering effect on noisy input to model the battery nonlinear dynamic is proposed to estimate the state of charge (SOC) based on a SFNN model.
