The paper presents the structure of the designed and built prototype of a device for testing the batteries in electric vehicles. The design goal was to estimate the health of individual cells of the battery pack powering the electric powertrain. The article presents the capabilities and functions of the device built with ATMEL ATmega32 microcontroller. The testing of the device operation was carried out on a battery pack of the Fiat Panda EV car. The test results are presented in the final part of the paper.

Fe/Fe3O4/Graphene composite electrode material was synthesized by a thermal reduction method and then used as anode material along with Nickel cathode in rechargeable Ni/Fe alkaline batteries in hybrid electric vehicles. Reduced graphene /Fe/Fe3O4 composite electrode material was prepared using a facile three step synthesis involving synthesis of iron oxalate and subsequent reduction of exfoliated graphene oxide and iron oxalate by thermal decomposition method. The synthesis approach presents a promising route for a large-scale production of reduced graphene /Fe/Fe3O4 composite as electrode material for Ni/Fe rechargeable batteries. The particle size and structure of the samples were characterized by SEM and XRD.

Reversible deposition of magnesium on electrodes and its anodic dissolution in non-aqueous solvents are possible only from particular electrolytes, like ethereal solutions of Grignard reagents or recently elaborated complexes of alkylaluminum chlorides with dialkylmagnesium. The above processes are important in developing rechargeable magnesium batteries but can also help organic chemists for deeper understanding of the formation of Grignard reagents in classic reactions. Magnesium deposition from solutions of Grignard reagents has been known for more than 80 years but repeated efforts to explain the reason of reversibility and find other suitable electrolytes were unsuccessful for a long time. Recently, a sig-nificant progress was achieved due to the application of modern spectroscopic methods combined with electrochemical measurements. These results are presented. They include a finding of Liebenow [27, 28] that the magnesium dissolution strongly depends on the morphology of depositions and conclusions from reports of Aurbach and coworkers [12, 32-42] which explained in detail characteristics of the magnesium surface in a contact with different electrolytes, the role of adsorption of ions and radicals in electrode processes and the nature of electro-active species in various solutions. Finally, the proposed electrode mechanism of the magnesium deposition and dissolution from different electrolytes, shown in Scheme 2 and reactions (12)-(16), is presented.
