Description:DISCHARGE CURRENT OF BATTERY
TECHNICAL FIELD
[0001] The present subject matter generally relates to automotive engineering. More particularly, but not exclusively to a system and a method for controlling discharge current of a battery associated with a vehicle.
BACKGROUND 5
[0002] Electric vehicles (EVs) have gained significant traction in recent years due to their environmental friendliness and potential to reduce reliance on fossil fuels. However, EVs face several technical challenges that affect their performance, including issues related to battery management and power delivery. One crucial aspect of EV performance is acceleration, which 10 directly impacts the driving experience and usability of the vehicle.
[0003] Traditional EVs often suffer from limitations in acceleration due to suboptimal management of battery discharge current. The Battery Management System (BMS) typically imposes a maximum discharge current limit, which can restrict the power output of the vehicle, particularly during 15 high-demand scenarios such as rapid acceleration or driving uphill. This limitation results in reduced acceleration capabilities, negatively impacting the overall driving experience and limiting the market appeal of EVs.
[0004] Furthermore, existing approaches to managing battery discharge current may not adequately address Varying needs of different driving modes, 20 such as eco mode and power mode. In eco mode, where energy efficiency is prioritized, the vehicle may throttle back power delivery excessively, resulting in sluggish acceleration and diminished performance. Conversely, in power mode, the vehicle may experience limitations in acceleration due to conservative discharge current settings imposed by the BMS. 25
[0005] Therefore, there is a need in the art for innovative solutions that optimize battery discharge current management in EVs which addresses at least the aforementioned problems and other problems of known art.

[0006] Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of described systems with some aspects of the present disclosure, as set forth in the remainder of the present application and with reference to the drawings. 5

14
[00057] In an embodiment, the method may comprise transmitting, by the VCU (106), the warning notification to a mobile app/electronic device of a fleet owner of the vehicle. The method may comprise controlling, by the VCU (106), the first discharge current to be provided to the motor (110) based on a timer. 5
[00058] In a scenario, an electric vehicle (EV) is considered. The EV is equipped with a VCU responsible for managing battery discharge current. The EV's battery management system (BMS) continuously monitors battery state of charge (SOC) and other parameters, sending this data to the VCU. The VCU detects the driving mode of the EV, which could be eco mode or 10 power mode, based on user selection or predefined conditions.
[00059] In the eco-mode, if the SOC of the battery is below a certain threshold and the discharge current exceeds a predefined limit, the VCU initiates an iterative process to reduce the discharge current gradually. For example, if the current discharge rate is 50 amps and the limit is set to 35 15 amps, the VCU will decrease the discharge current by 1 amp per second until it reaches 35 amps. This ensures that the vehicle maintains efficiency and battery health while still providing adequate performance for eco-conscious driving.
[00060] In power mode, the VCU adjusts the discharge current based on real-20 time factors to optimize performance. If no warning is present and the discharge current is not equal to the battery discharge current, the VCU iteratively increases the discharge current to a set threshold, such as 95 amps, at a rate of 1 amp per second. If a warning is detected or the discharge current exceeds the battery discharge current, the VCU gradually reduces the 25 discharge current to match the battery's capabilities, ensuring safety and preventing damage. Throughout the process, the VCU continuously monitors battery parameters and adjusts the discharge current accordingly to maintain optimal performance and safety.
[00061] If a warning related to excessive discharge current is detected, the 30 VCU provides a notification to the driver via the vehicle's display or
15
dashboard, alerting them to the issue and ensuring awareness. The disclosed system and the method operate adaptively, dynamically adjusting discharge current based on driving conditions, battery state, and user preferences to provide a seamless and optimized driving experience. By dynamically controlling discharge current in this manner, the disclosed system and the 5 method ensures that the EV delivers optimal performance while prioritizing safety, efficiency, and battery health, thereby enhancing the overall driving experience for users. [00062] In another scenario, the electric vehicle (EV) is equipped with the disclosed system and the method, consisting of a Vehicle Control Unit (VCU) 10 responsible for managing battery discharge current. The VCU communicates with the Battery Management System (BMS) to receive real-time data about the battery, including state of charge (SOC) and maximum discharge current limit. The VCU detects the driving mode of the EV, which can be either eco mode or power mode, based on user input or predefined conditions. Suppose 15 the predefined threshold for SOC in eco mode is 20%. If the SOC falls below 20% and the discharge current exceeds 35 amps (as an example), the VCU initiates an iterative process to reduce the discharge current gradually. Starting with a discharge current of 50 amps, decrease the discharge current by 1 amp per second until it reaches the limit of 35 amps. This gradual 20 reduction ensures efficient energy usage and extends battery life while maintaining adequate performance for eco-friendly driving.
[00063] In power mode, suppose the maximum discharge current limit set by the BMS in power mode is 85 amps. If no warning is present and the discharge current is not equal to the battery discharge current. The VCU increases the 25 discharge current to the maximum limit, say 95 amps, at a rate of 1 amp per second. This allows the EV to achieve optimal performance for power-demanding situations. If a warning is detected or the discharge current exceeds the battery discharge current. The VCU gradually reduces the discharge current to match the battery's capabilities, preventing overheating 30 or damage. For example, if the battery can only handle 80 amps, the VCU decreases the discharge current from 95 amps to 80 amps at a rate of 1 amp
16
per second. Throughout the process, the VCU continuously monitors battery parameters, including SOC, discharge current, and warnings. If any abnormalities or warnings are detected, the VCU adjusts the discharge current accordingly to ensure safety and reliability. In case of a warning related to excessive discharge current, the VCU provides a notification to the driver 5 through the vehicle's display or dashboard. This alert informs the driver of the issue and prompts appropriate action, such as reducing power demand or adjusting driving behaviour. [00064] The disclosed system and the method operate adaptively, dynamically adjusting discharge current based on real-time conditions, 10 driving mode, and battery characteristics. This adaptive control ensures that the EV delivers optimal performance while safeguarding battery health and maximizing efficiency. By implementing the disclosed method and system with specific values and parameters, the electric vehicle can effectively manage battery discharge current, optimize performance, and enhance the 15 overall driving experience for users.
[00065] The disclosed system and the method enable dynamic discharge current control. Unlike fixed discharge current limits or mode-based settings, the disclosed system and the method dynamically adjusts the discharge current based on real-time factors such as battery state of charge (SOC) and 20 driving mode. This dynamic control allows for optimal performance optimization across various driving conditions and modes.
[00066] The disclosed system and the method provide enhanced acceleration. By intelligently managing the discharge current, the disclosed system and the method improves acceleration capabilities, especially in power-demanding 25 scenarios. This leads to a more responsive and enjoyable driving experience for EV users, without compromising battery safety or longevity.

The disclosed system and the method adapt to changing driving conditions and battery states, continuously optimizing performance while 30 balancing factors such as acceleration, efficiency, and battery health.
