Abstract
Batteries are the energy source that provides energy to the vehicle for the first movement. Batteries used in motor vehicles nowadays are usually lead-acid batteries. This paper introduces the basic components of lead-acid batteries and describes the concept of a battery capacity test. The general definition of the standard for testing, EN50342, and the required conditions are presented. Furthermore, a cost-effective capacity tester for heavy-duty lead-acid batteries in compliance with the standard was developed and introduced.
Highlights
A battery is the only part to which the vehicle is dependent, regardless of vehicle type, and its technical characteristics have changed little over time
Almost 98% of the materials used in a lead-acid battery are recyclable
The advantages and disadvantages of lead-acid batteries used in the automotive industry were compiled
Summary
A battery is the only part to which the vehicle is dependent, regardless of vehicle type, and its technical characteristics have changed little over time. If your battery runs out, you will stay on the road. You can find the auto electrician, the tire repairman anywhere, anytime, but the battery is not something that can be found on the road. Battery failures are in part influenced by driving habits, the liberal use of auxiliary loads, hot climate conditions, start-stop, and battery mount. Even under the best conditions, a quality battery ages and this manifests itself in a gradual drop of capacity. A common failure of the battery is the capacity fade. The battery does not work in accordance with the capacity produced can be given as an example. A battery with a capacity of 220Ah, according to the European Standard (EN50342) for 20 hours until 10.5 V below 11 A must give a rating in the battery capacity test [1]
