Fast and Integrated Chargers for Lithium Ion Batteries

Abstract

Electric vehicles were introduced in the year of 1908, where they have larger battery for power supply. Now- a- days the technique for charging e-bikes is done either by using grid supply or solar power. This paper says about charging circuit for batteries which uses both solar power and power from the grid to charge the electric vehicles. The charging with solar helps to reduce the emission from power grid. Ever-increasing demand for fuel supply, rising fuel prices, and increased environmental awareness among masses are paving the way for electric vehicles (EVs). Although, in recent years EV market has seen an exponential growth, one of the major challenges faced by this automotive/vehicular market. Now the Indian government had ordered to Indian Vehicle Association to launch the electric vehicles with in 2023. But the charging of electric Batteries has taken more time, which compare to fossil fuel and gas. To overcome this issue use of turbo charger, to reduce the charging time as well as self charging by solar during running time is proposed. The charger uses the source from EB grid and solar as well as at parking time. The results proves that proposed work have reduced the charging time of the lithium ion battery compared to the conventional charging technique and all under controlled temperature raise.

Development of fast and hybrid charger for lithium ion batteries in light weight electric vehicles

“…Supply from both the grid and solar panel is given to the controller, where controller compares the effective voltage and gives the supply to DC‐DC converter. Charging of battery can be done throughout the day without any distortion by pursuing this technique 40 . The battery is charged through solar supply even though the supply from grid is available.…”

Wire-Free Vehicle Charging Using Solar System

“…The number of components and the complexity of control may both be decreased with a long rail. [20] The benefit of employing a long transmission rail is that it can supply steady power .and current to an EV when it enters the rails near field. However, if the rail is powered by a single source of power, the cost of the components rises.…”

Stability Analysis of Neuro-Adaptive SMC-Based Current Sharing Technique for Multiphase Converters in Battery Charging Applications

“…The value of , and are updated by the adaptive neural network algorithm given below, From the above algorithm's decision, the updated PI controller gains of the respective voltage and current in (19) and (20)…”

“…Some of the NN techniques like nested order NN [17], approximation techniques, adaptive current control with NN [18], and self-tuning PI with adaptive NN [19] are elaborated in the literature. Similarly, some of the fast and integrated charging techniques are discussed in [20,21] This paper considers an integrated DC power system having boost converters connected in parallel on the source side and the load side as well. The source side converters convert the source voltage to the load bus voltage and load side converter act as the charging circuit for the battery chargers.…”
