Specification

DESC:TECHNICAL FIELD [0001] The present invention relates generally to an Energy Conditioning System (ECS) for charging an Energy Storage System (ESS) of a vehicle, and maintaining the temperature of the energy conditioning system (ECS) by using an air exhausting unit in order to condition the fluid that circulates to the ESS, hence increasing the life span of the ESS. BACKGROUND [0002] An Electric vehicle battery (EVB) also known as a traction battery or Energy Storage System (ESS) is a rechargeable battery that is used to power the motors of the vehicle which provide driving force to the vehicle. Many electric vehicles are capable of being charged at very fast rates. This causes the battery to heat up significantly. [0003] The high temperature of the battery reduces the lifespan of the ESS and increases the risk of thermal runaway. The heated Energy Storage System (ESS) may lead to the deterioration of electronic components placed inside the vehicle in terms of life and increases the chances of their failure during operation leading to fires. This also affects the heat exchange efficiency between the fluid and the heat exchanger of a TCS (Temperature Conditioning Subsystem) that further heats up the ECS. [0004] Therefore, ECS cooling is necessary to reduce the temperature during fast charging or when the demand on the battery is high. This also increases the efficiency of charge transfer and reduces the degradation of the ESS. [0005] Many conventional methods are used for cooling the ESS by extracting heat from the fluid that circulates to the ESS. Forced liquid cooling is the traditional approach for cooling the ESS. However, this method is no longer efficient enough to manage temperatures in high-performance batteries and power electronics that need to be charged at very high rates. [0006] For example, U.S. Patent 10189362 B2, shows a vehicle charging station having degraded energy storage units for charging an incoming vehicle and methods thereof. Further, the charging station may include at least one energy storage unit and a controller determining a time before a vehicle arrives at the charging station and calculating the power to be supplied by the at least one energy storage unit and power to be supplied by a power grid based on the time before the vehicle arrives at the charging station. [0007] Another example, CN Patent 108016315 A, shows a kind of safety protecting method of electric charging station, system and terminal device. Further, a charging voltage, a charging current, and a charged state of a battery are determined. When the charged state of the battery is abnormal, then the connection between the battery and the battery charger is disconnected and sends a battery abnormal alarm to a user. [0008] Therefore, existing methods and devices do not disclose the method for extracting the heat from an energy storage system (ESS). Hence, there is a need in the art for improved energy conditioning system and method for an electrically powered vehicle. [0009] In order to overcome the aforementioned drawbacks, there is a need to provide an energy conditioning system (ECS) for a vehicle and a method that is an enhancement to the conventional systems and methods. This system is capable of maintaining the temperature of the ECS for conditioning the temperature of the fluid before delivering it to the ESS according to the analysis of a plurality of parameters based on a plurality of conditions. OBJECT OF THE DISCLOSURE [0010] A primary objective of the present invention is to overcome the disadvantage of the prior art. [0011] Another objective is to provide an energy conditioning system (ECS) for a vehicle and a method for conditioning the temperature of the fluid before delivering it to an energy storage system (ESS) according to the analysis of a plurality of parameters based on a plurality of conditions. [0012] Another objective is to provide the energy conditioning system for the vehicle and the method that includes an air-exhausting unit that maintains the temperature of the ECS for successfully conditioning the temperature of the fluid. [0013] Another objective is to provide the energy conditioning system for the vehicle and the method for providing hassle-free charging services at the ECS.
