Energy Storage in Electric Vehicles: Trends, Challenges, and Potential

In the context of increasing awareness of environmental protection, the trend towards using green energy is becoming a crucial focus, especially in the electric vehicle industry. The shift from traditional energy sources to green energy not only reduces greenhouse gas emissions but also promotes the development of electric vehicles and efficient energy storage solutions.

Current Status of Electrical Systems and Energy in Vietnam Vietnam is facing a diverse energy landscape. Solar energy, with significant potential, contributes only about 0.01% to the total electricity output. Wind energy, despite its high potential, encounters challenges with high initial investment costs and grid connectivity issues, making up approximately 0.5% of the total output. Coal energy accounts for 36.4% of the total electricity output, posing significant environmental and human health consequences. Hydroelectric power contributes 35.8%, facing environmental impact challenges.

In the context of Vietnam’s energy landscape, the electrical system largely relies on traditional energy sources such as coal and oil, posing significant challenges for high-capacity renewable energy storage. This scenario drives the robust development of the electric vehicle industry and underscores the essential need for energy storage on vehicles.

Why Energy Storage in Electric Vehicles is Necessary? Energy storage in electric vehicles plays a crucial role in optimizing performance and fuel efficiency for journeys. Compared to primary energy sources like gas and oil, storing electric energy is challenging due to its high storage capacity. Researchers have focused on developing storage technology through electric vehicle battery systems and motors, enabling the regeneration and storage of excess energy for subsequent journeys.

Energy Storage Technologies in Electric Vehicles

a. Lithium-ion Batteries Lithium-ion batteries are highly praised for their low self-discharge rate and high energy density. This type of battery has a longer lifespan and better withstands harsh environments compared to lead-acid batteries. This technology eliminates the risk of explosions as there is no combustion process during operation.

b. Solid-State Batteries Solid-state batteries use solid electrolyte materials instead of liquid electrolyte solutions. This difference provides flexibility in design and the ability to maintain high capacity over multiple charging cycles.

c. Redox Flow Batteries This type of battery is suitable for storing energy from solar or wind sources, improving efficiency and stability in electric vehicles.

d. Sodium-ion Batteries New sodium-ion batteries maintain over 80% capacity after 1,000 charge cycles. While not achieving the same electrical density as lithium-ion batteries, they provide diversity in energy storage options.

Expected Impacts of These Solutions These energy storage technologies enhance the performance of electric vehicles, improving mobility and minimizing environmental impact. Lithium-ion batteries, known for their stability and safety, remain a popular choice. New technologies such as solid-state batteries and redox flow open up opportunities for innovation and optimization.

Conclusion As of now, energy storage in electric vehicles is not just a trend but a vital necessity, driving the development of the electric vehicle industry. Diverse energy storage technologies not only deliver high performance but also contribute to environmental protection goals and the transition to green energy sources.
