High voltage batteries diagnostic

Hybrid vehicles history begins between XIX and XX century because then has been constructed first hybrid vehicle project. The first men who produced electric propulsion mounted in front hubs connected with generator powered by spark ignition engine was Ferdynand Porsche. Vehicle was called Lohner – Porsche Electromobile. The first en masse produced hybrid vehicle was the first generation Toyota Prius. These model premiere was in 1996, and production started one year later. Vehicle was equipped in 1,5 dcm 58 hp spark ignition engine with added electric propulsion generated 40 mechanical hp. There has been mounting 72 hp spark ignition engine and 44 hp electric generator since 2000. Fuel consumption of these model was 5 liter on 100 km. Beginning XXI century 95% hybrid vehicles were Toyota Prius. The biggest competitor of Toyota Prius was Honda Insight. Lexus and Mercedes started producing hybrid vehicles few years later. The most popular brands selling hybrid vehicles are Toyota and Lexus – Toyota Motor Corporation. Article describes high voltage battery example diagnostic possibilities in a hybrid or electric vehicle. Constructing vehicle models using two propulsion systems (spark ignition engine and electric generator) cause development and increase control system devices. The measurements has been made by using various diagnostic devices for example: diagnostic scanner mega macs 66, high voltage battery tester. Reading faults code is not enough so it is necessary to use data list what describes this article.
