DESC:FIELD OF THE INVENTION
[001] Present invention relates to a system and a method for adaptive charging a battery pack of a vehicle. More particularly, the present invention relates to the system and the method for adaptive charging the battery pack of the vehicle based on inputs received from at least one of a user of the vehicle, the battery pack and a charging unit.
BACKGROUND OF THE INVENTION
[002] In recent past, one of the major innovations in the field of Electrical and Electronics is in the field of battery charging. The focus is on the effective methods for charging a battery while making sure that the battery has a long life. The conventional development in this field is focused predominantly on fast charging or quick charging of the battery. Such a development is towards vehicles, particularly electric vehicles, in order to reduce idle time or downtime of the electric vehicles during charging of the battery.
[003] However, one of the major drawbacks of fast charging is the reduction in battery life. This is due to the fact that, fast charging can adversely affect the life of the battery, due to factors such as an increase in battery temperature beyond a critical point, loads connected to the battery and the like. Such a scenario may require a user to change the battery frequently or prematurely than when the battery is charged correctly.
[004] Further, the user may leave the battery being charged for a long period of time, say overnight. Such a situation may cause the battery to be charged unnecessarily, even when the battery may have been fully charged, leading to degradation in life of the battery, which is undesirable.
[005] Additionally, there are several technical problems and challenges associated with fast charging such as heat generation and thermal Management caused during fast charging. At this scenario, the battery is subjected to increased heat generation within cells of the battery which degrades the performance of the battery, thereby reducing the battery lifespan and pose safety risks. Further, frequent fast charging of the battery can accelerate the degradation of cells of the battery leading to reduced capacity and shorter overall battery lifespan. As such, managing the trade-off between fast charging and battery longevity is a significant challenge. Also, fast charging often involves higher voltage and current levels, which can create stress on the cells of the battery and associated components. Thus, maintaining proper voltage and current regulation while preventing overcharging or over-discharging is crucial. Additionally, during fast charging, the voltage of the power supply can sag due to the high current demand. Such a scenario can lead to power quality issues and potentially affect the charging speed and efficiency.
[006] Furthermore, some battery chemistries used in electric vehicles are more suitable for fast charging than others. Lithium-ion batteries, for example, can experience more pronounced issues with heat and degradation during rapid charging. Research into new battery chemistries and materials that can withstand fast charging while maintaining performance is ongoing. Moreover, electrical infrastructure, including power grids and charging stations, may not always be capable of providing the necessary high-power levels for fast charging without causing grid stability issues or requiring expensive upgrades. Further, while fast charging stations are becoming more common, their availability can still be limited in certain areas, potentially leading to long waiting times during peak usage.
[007] In view of the above, there is a need for a system and a method for adaptive charging a battery pack of a vehicle which addresses one or more limitations stated above.
