Low voltage hybridization: How to lower costs, enhance CO2 benefits and transmission impacts
Dr Olivier Coppin, Innovation & scientific development director, Valeo, France
By scalable solutions low voltage hybrid systems are real first steps in hybridization field. With the extended power field offered by 48V components, more vehicle segments and applications can have more benefits at a still limited over cost. We will introduce a new kind of hybridization which can address a lot of vehicle engine adaptation fields.
Components and electrical architecture modularity are ways to lower the material and the vehicle integration costs. This modular mindset is also a way to offer scalable functions and solutions to have the best right sizing and thus right costing of the system. This also contributes to procure the best end user value / cost ratio. Finally, this can contribute to a large application field for low voltage hybrid systems and a greater vehicle fleet CO2 reduction.
What is new?
We will examine how 48V system can address more efficient hybridization architectures (from P0 to P4) allowing more CO2 emission reduction and even open the gateway for low cost pure electrical vehicle. Then we will illustrate how the different hybridization architectures can be addressed in a modular building block structure for components.
We will also present some energy optimization strategies to maximize the CO2 benefits in all day driving phases in a quite robust way. These means use all the hybridization possibilities and adapt itself to the incoming driving situation including driver will, the traffic condition ahead and the internal condition of the energy needs of the car.
At the end, we will introduce the impacts of hybridization and future vehicle functions such as automated driving on transmission and a global consideration of the requests for a dedicated one.
