Investigation causes of the premature capacity loss in accumulator for hybrid electric vehicles
Vystrčil, Marek ; Bilko, Radek (referee) ; Bača, Petr (advisor)
This thesis describes the results of two successive experiments. The first was focused on the influence of impurities in the active mass of negative electrode in PSoC (Partial State of Charge) mode, which simulates the conditions occurring in HEV (hybrid electric vehicle). In the second experiment, cells with the same additives were exposed to optimum downforce 4N/cm2, by which we wanted to prove the influence of pressure on life of VRLA (Valve Regulated Lead Acid) cells working in operating HEV conditions.
Influence of pressure in the lead-acid batteries for hybrid electric vehicles.
Svoboda, Marek ; Vaněk, Jiří (referee) ; Bača, Petr (advisor)
Lead-acid batteries of hybrid electric vehicles (HEV) are functioning in PSoC regime (Partial State of Charge). In PSoC regime new fail mechanisms occur. These mechanisms usually lead to nonreversible sulphation of negative electrodes. Main aim of this research is to avoid negative electrode sulphation and to improve lifetime of lead-acid accumulators used in HEV.
