In 2023, skipping battery actions increased balancing costs by £24 million. This is calculated by the total cost of the actual dispatches in the Balancing Mechanism minus the cost of the cheaper battery alternative. 9 million occurred in October 2023, closely followed by December 2023.
Battery balancing can be accomplished using two main methods: passive balancing and active balancing. Passive balancing relies on resistors to discharge excess charge from high-voltage cells, while BMS active balancing uses sophisticated components like transformers, inductors, or capacitors to transfer energy between cells.
One of the most important parameters of estimation the performance of battery cell balancing is the equalization time. Other parameters such as power efficiency and loss are related to the balancing speed.
Other risks associated with heat causing the battery to overheat or even get out of control known as thermal runaway. To counteract these challenges, EV manufacturers practice battery balancing to guarantee that all the cells within a pack are working at their given voltage, as well as charge levels.
The research delved into the characteristics of active and passive cell balancing processes, providing a comprehensive analysis of different cell balancing methodologies and their effectiveness in optimizing battery efficiency.
This article has conducted a thorough review of battery cell balancing methods which is essential for EV operation to improve the battery lifespan, increasing driving range and manage safety issues. A brief review on classification based on energy handling methods and control variables is also discussed.

Carbon fiber-based batteries, integrating energy storage with structural functionality, are emerging as a key innovation in the transition toward energy sustainability.
Here, an all-carbon fiber-based structural battery is demonstrated utilizing the pristine carbon fiber as negative electrode, lithium iron phosphate (LFP)-coated carbon fiber as positive electrode, and a thin cellulose separator. All components are embedded in structural battery electrolyte and cured to provide rigidity to the battery.
Building on the trailblazing carbon-fiber-as-a-battery work started at Sweden's Chalmers University of Technology, deep-tech startup Sinonus is working to commercialize a groundbreaking new breed of multifunctional carbon fiber.
In a 2018 CTU study, researchers found that carbon fiber-based structural batteries could significantly reduce the weight of vehicles and aircraft. In 2021, they achieved a significant milestone by announcing a structural battery with ten times the performance of previous versions.
Researchers at Chalmers, in collaboration with Carbon Nexus at Deakin University, have shown how the manufacturing process can tailor carbon fiber's multifunctional properties. An important step in the development of structural batteries.
Increased international collaboration will be vital in accelerating technological progress and addressing existing challenges. As the field matures, carbon fiber-based batteries hold significant promise for advancing sustainable energy systems and contributing to a decarbonized future.
Sinonus CEO Markus Zetterström stated they have developed an innovative carbon fiber composite that doubles as a battery. “By substituting part of the structural material in various applications with our multipurpose composite, it is possible to increase electrical storage capacity without adding weight or volume,” he explained.
According to Altech, it has designed the Cerenergy Sodium Alumina Solid State (SAS) 60 KWh battery pack (ABS60) for the renewable energy and grid storage market.

The national electric utility of Senegal, Senelec, has signed a 20-year CCA with Infinity Power for a battery energy storage project.
Infinity Power, a joint venture between Egypt's Infinity and UAE's Masdar, has sealed a 20-year capacity change agreement related to a 40-MW/160-MWh battery energy storage systems (BESS) project with Senegal's national electricity company Senelec. Infinity Power will build the battery at the Tobene substation in the city of Thies.
The planned facility, described as one of the largest of its kind in West Africa, will help Senelec stabilise the country's electricity grid and pave the way for further renewable energy growth in Senegal.
Cairo, Egypt and Abu Dhabi, UAE - 13 November 2023: Infinity Power, a joint venture between Egypt's Infinity and UAE's Masdar, announced today the signing of a 20-year Capacity Change Agreement with Senelec, Senegal's national electricity company to supply 40MW through a battery energy storage system (BESS).
Expected to be one of the lowest cost producers of electricity in Senegal, the project is helping reduce the cost of electricity generation in the country, which has one of the highest generation costs in Sub-Saharan Africa. Infinity Power is Africa's largest pure play renewable energy provider.
The battery system is expected to provide ancillary services in power transmission and reduce the local grid's dependence on thermal power plants. According to news reports, Senelec is said to have estimated that the BESS will save the grid US$165 million over its operating lifetime.

[PDF Version]Battery degradation refers to the gradual loss of a battery's ability to store and deliver energy over time. This process occurs due to various factors such as chemical reactions, temperature extremes, charge/discharge cycles and aging.
Mitigating battery degradation is critical for extending the lifespan of lithium-ion batteries, particularly in EVs and ESS. Here are several strategies to minimize degradation: Maintaining the battery charge between 20% and 80% is one of the most effective ways to prevent overcharging and deep discharging, which accelerate degradation.
Figure 2 outlines the range of causes of degradation in a LIB, which include physical, chemical, mechanical and electrochemical failure modes. The common unifier is the continual loss of lithium (the charge currency of a LIB). 3 The amount of energy stored by the battery in a given weight or volume.
Battery degradation rates vary depending on the type of battery used in energy storage systems (ESS), with the most common types being lithium-ion (Li-ion), lead-acid and flow batteries. These are the most widely used in ESS and typically degrade at a rate of 1–3% per year under standard operating conditions.
As a key factor, the discharge rate has great impacts on both the performance and degradation trend of batteries [1, 4, 5]. However, to our knowledge, the effects of discharge rate on battery capability degradation, especially its quantitative analysis is still an open and challenging problem.
For energy-focused applications, knowledge of degradation will benefit EV owners by reducing warranty costs and minimising degradation performance and range losses over their car's lifetime. Conidence in the state-of-health of the battery will also improve residual values, reducing the total cost of ownership.

Millions of UK homes could successfully switch to low-carbon electrified heating whilst easing pressure on the electricity grid by using innovative heat battery technology.
As mains gas is the only heating source for over two-thirds of UK households, switching to heat batteries can be transformational. However, not all heat batteries are created equal. While some are predominantly aimed at water heating, others are specifically designed for space heating. Different materials, different applications
The main feature of heat batteries is moving most of your heating demand to low cost off-peak tariffs, so whilst it does not reduce how much energy you need to buy as much as a heat pump, it does reduce how much you pay for electricity.
Heat batteries use dense natural materials to store heat at high temperatures that can be released slowly over a 24 hour period. Old fashioned electric storage heaters were a form of heat battery, although arguably not very effective at keeping homes warm throughout the day as they couldn't store the heat for long.
Storing energy as heat isn't a new idea—steelmakers have been capturing waste heat and using it to reduce fuel demand for nearly 200 years. But a changing grid and advancing technology have ratcheted up interest in the field.
Modern heat batteries have evolved significantly. They can store more energy and use smart technology to optimise when to charge and discharge. Their development coincides with more 'time of use' tariffs, whereby households are incentivised to shift more of their energy use to much lower off-peak tariffs.
There are currently two types of heat battery for domestic use: Sunamp's hot water unit and Tepeo's ZEB boiler (stands for Zero Emissions Boiler). Sunamp uses a heat exchanger submerged into a 'phase change' liquid that releases energy as it freezes. NB Sunamp can only supply hot water, not heating.
