The battery supplies the electrical energy to start and operate the engine, lights, control units and numerous subsystems. A reliable power source is essential in the commercial vehicle sector in particular – not only for starting, but also for on-board electrical system applications such as control, lighting or measuring units.<\/p>\n<\/div>
In the store you will find starter batteries in various capacities as well as main switches for battery systems (e.g. 12-48 V). These components enable both the replacement of energy storage systems and safe disconnection or disconnection if necessary.<\/p>\n<\/div><\/div><\/div>
The battery must match the vehicle electrical system (e.g. 12 V, 24 V) and the power requirements of your vehicle.<\/p>\n<\/div><\/div><\/div>
The dimensions, pole arrangement and installation position must be selected so that the battery fits easily into the available space.<\/p>\n<\/div><\/div><\/div>
Make sure that the battery and the main switch are designed for the usual operating conditions – e.g. temperature changes, vibration load or switch-off functions.<\/p>\n<\/div><\/div><\/div>
24-volt systems and maximum capacity in trucks<\/strong>\nBatteries in trucks are designed for much higher requirements than in cars. Most heavy-duty vehicles operate with a 24-volt on-board electrical system, which is usually realized by two 12-volt batteries connected in series. These batteries must not only provide the high electrical energy required to start the large-volume diesel engine, but also offer significant cycle capability and capacity (Ah) for the numerous consumers during standstill (cool box, auxiliary heating, multimedia). The cold start performance (CCA) must be extremely high in order to reliably cover the massive power requirement of the starter motor even at low temperatures.<\/p>\n<\/div><\/div><\/div>Vibration, continuous operation and robustness<\/strong>\nThe truck batteries are exposed to extreme loads due to their installation position and continuous driving over long distances. They must be able to withstand strong vibrations and shocks without the internal plate structures becoming loose or damaged. This requires special, reinforced housings and internal constructions (e.g. using fleece separators such as those used in AGM or EFB technologies). In addition, truck batteries must be able to withstand continuous discharge during rest periods (hotel function) without deep discharge damage and quickly regain full charging capacity via the powerful generator.<\/p>\n<\/div><\/div><\/div>Safety, disconnection and battery management<\/strong>\nIn the truck sector, the safety of the battery system through components such as the main battery switch (emergency stop or disconnector) is required by law and is essential. This enables the safe and quick disconnection of the on-board power supply in the event of maintenance or danger. In addition, modern truck fleets are often equipped with complex battery management systems (BMS). Replacement batteries must therefore not only have the correct voltage and capacity, but also the electrical characteristics (e.g. end-of-charge voltage) in order to be correctly integrated into this system and ensure optimum charging and avoid costly failures due to undersupply of critical electronic control units.<\/p>\n<\/div><\/div><\/div><\/div><\/div>Expert Guide: Everything You Need to Know About Batteries and Main Switches<\/h2><\/div>\n\n<\/i><\/i><\/span>What is the function of the battery in a commercial vehicle?<\/span><\/a><\/h4><\/div>The battery supplies the electrical power needed to start and operate the engine, lights, control units, and numerous subsystems.
