The Future Of Battery Management System For Electric Vehicle

Table of Contents

Introduction

Certainly, EV – electric vehicles are not the future tense anymore, and you might see people around you buying an EV for themselves, gearing up with the advancements in the constantly changing mobility segment.

The whole concept of E-mobility is like the center point of a see-saw built to
1. Mitigate the foreign dependency on oil and gas
2. Nurture a cleaner and healthier space towards sustainable development

Analyzing the Electric Vehicle Market 2021 to 2028

The Electric Vehicle segment is constantly acquiring the automotive market YoY. A report by Fortune Business Insights suggests that the global electric vehicle market opportunity is set to scale from USD 287.36 billion in 2021 to USD 1,318.22 billion in 2028 at a CAGR of 24.3% by 2028.

By 2026, the Electric Vehicle Market in India is predicted to reach USD 47 billion with a CAGR above 44% (2021-2026) estimated at USD 5 billion in 2020.

The future scope of Electric Vehicles is determined by; Regulation, Consumer Behaviour, and Technology. Fundamentally, these topmost crucial factors drive the road towards sustainable mobility solutions.

1. Policies and Norms:

The IEA report outlines the existing measures and declared targets and initiatives country-wise.

As per the report;

• The European Union stands on the top in incentivizing EV deployment. The proposal from the nine-member committee states to phase out the sale of fresh IC Engine passenger vehicles.
• The Biden administration has set a 50% market acquisition target for the upcoming decade. By 2025, California has set the target to achieve 1.5 Million Zero-Emission Vehicles (ZEV) and 5 million vehicles by 2030.
• India targets a 25% share of EVs in sales by 2024, intending to acquire 30% of the total LDV (Light Duty Vehicle) market by 2030.

The majority of the regions have already implemented alternative mobility modes such as rental E-bikes. The unison of the most prominent regions is converging mostly towards adopting the EV as shared mobility to reduce private vehicle use and traffic congestion.

2. Behavior of the Consumer:

People are accepting the change and aligning with the sustainable modes of mobility. More than 20% of Germans already use ride-pool for their daily commute.

However, a recent survey by an automotive research company highlights the concerns related to the EV battery capacity. The EV drivers are pessimistic about the battery range, unlike an ICE vehicle driver who can find refueling stations distanced in almost a mile’s range. Here is where the need for an improved Battery Management System for Electric Vehicle comes into play.

3. Role of Technology:

The newly developing autonomous, electric, and shared mobility concepts have attracted the industry with $400 billion in investments cumulative in the last decade. Thanks to the far-sighted investors who have accelerated the execution of innovative ideas to improve battery technology, placing EV right next to a conventional vehicle.

What is a Battery Management System?

The BMS (Battery Management System) is a performance management framework for monitoring the status of the battery and determining its health and charge status. Battery status can be monitored remotely on-screen/tablet/smartphone.

The BMS accurately determines the State of Charge (SOC) and State of Health (SOH) for the battery, which are vital parameters required for ensuring the battery’s longevity.

It also supports passive cell balancing, crucial when the battery is overcharged or completely discharged.

The Role of Battery Management System for Electric Vehicles

Particularly, a BMS is needed for E-bikes and EVs, where the motor current row is high. The batteries can go out of balance because of unequal load distribution, leading to permanent damage or failure in the life cycle.

If you are an EV owner, you know that it is economically viable to commute to work vice-versa. You could either charge at home overnight or at the corporate parking garage. But the anxiety arrives on the weekends, whether to go for a long drive, unaware about the range of a trip.

To solidify the ground of improvement, the EVs follow a modular approach towards energy conversion and storage for the batteries. Here is how an affordable and reliable Battery Management System for Electric Vehicle is important:-

• The BMS is the managing and commanding unit for your EV or E-bike’s battery pack to maintain longevity and ensure operational safety.
• Ideally, a BMS is an accurate predictor of the conditions the battery packs can be susceptible to, such as shocks, vibrations, overloading.
• It monitors and predicts accurate SOC(State of Charge) and SOH(State of Health), vital parameters for improving the overall battery performance.
• The continuous monitoring process immunes the battery from overcharging, temperatures, or any short circuits.
• Whenever the battery exceeds a safe limit voltage, the BMS cuts off the power supply from the battery.

How a Smart BMS Can Be EV’s Long-Term Companion

We must not overlook the fact that the battery is the heart of the EV, and a safety-critical system is a must to prevent any catastrophic failures. Considering BMS Battery Management System for Electric Vehicle as a self-check system, operational sustainability is well ensured.

With a wide range of EV options evolving in the market, a robustly smart BMS powered with reliable and multifaceted communication protocols can be very well suited for further development.
