48volt Battery\/Mild Hybrid<\/a> drive technology of a Mercedes Benz. In this post we will explain how this technology is applied to an Audi hybrid system.<\/p>\nMild hybrids, also called 48-volt mild hybrid systems (48-volt battery), are the most recent electrified version of hybrid powertrains. Designs vary from model to model, but the basic concept and system are the same. A small electric motor, which can be called an integrated starter generator (ISG), is connected to the engine and it works in tandem with the internal combustion unit to provide extra power for acceleration.<\/p>\n
Automakers use 48-volt systems to boost performance<\/strong>, but they also come with an inherent fuel-efficiency benefit: They share the engine\u2019s load in controlled scenarios, helping it to save fuel. Some companies, such as Volvo, employ mild-hybrid configurations with slightly different components. For instance, a Volvo ISG has 42 volt battery.<\/p>\n
\nThese systems don’t work like traditional hybrids or plug-in hybrids, because electric motors aren’t capable of powering the car on their own. Instead, the 48-volt system and ISG act as an assistant for the internal combustion engine at low speeds<\/strong>, which includes accelerating and starting the vehicle.<\/p>\n
