The electric vehicle is slow but steadily entering into the automotive market. Most of these vehicles are equipped with Li-ion batteries to store the electric energy. Despite of the charging velocity and the range issues of these vehicles, one of the major concerns of car manufacturers and clients refers to the battery ageing.
Similarly to laptops and mobile phones, the batteries from electric vehicles become less and less performing along its lifetime. This is the reason why the car manufacturers defined the end-of-life of a battery for automotive purposes when it has lost a 20% of its capacity to store energy.
This study analyzes the battery ageing of a Plug-in Hybrid electric vehicle along its lifetime. This study will present the factors that have some impact in the capacity fade, in which proportion they contribute to this capacity fade and how these factors are studied, controlled and analyzed.
Moreover, the driver's perception of the battery ageing will be evaluated and how the battery transmits these performance losses to the rest of components in the vehicle.
