LFP in energy storage

Lithium-ion batteries are an integral part of the transition to renewable energy, both for the automotive sector’s transition to green mobility, and for the transition to generating electricity from more reliable and sustainable technologies. As renewable energy sources such as solar and wind are intermittent and therefore unreliable power sources, energy must be stored for certain periods of time. Technologies are required to stabilize the grid by ensuring that energy is released into the grid or removed from the grid when necessary.

Energy Storage Analytics

Energy Storage Analytics

Battery storage systems are an essential component of the energy sector. However, they are complex systems that require special attention. The primary goal of storage owners is to maximize the profit possible from the storage system without taking on additional risk. This is where battery analytics comes into play.

Approaches to battery modeling

Approaches to battery modeling

In our everyday life, we are surrounded by increasingly complex products, which makes understanding these and their interaction within other systems more complicated. Nowadays, battery systems in electric vehicles consist of numerous, individual battery cells connected in series and parallel, with each battery cell containing various solid and liquid materials and other supporting components. To understand how these complex systems will behave, we build models or replicates, also known as “digital twins” of these complex systems to mimic their behavior and leverage the computational power to perform the required calculations.

Streamlining e-bus warranty discussions

Streamlining e-bus warranty discussions

A lot has happened in the world of electric buses over the past year. Many new projects have been announced or started. The early adopters – those that started introducing electric buses into their fleets four or five years ago – can offer helpful insights to the future for many. Over the past couple of months, ViriCiti and TWAICE have worked closely with such an early adopter on how to integrate data-driven decision making – focusing on batteries – to avoid timely and costly warranty discussions.

The Power of Signalling

The Power of Signalling

Autovista Group, TÜV Rheinland and TWAICE have teamed up to explore the potential impact of Battery Health Reports (BHR) on remarketing success of the battery electric vehicle (BEV) in a new whitepaper. Besides age and mileage, driver profile has a major impact on how long a battery lasts. In the absence of documentation of how a driver has treated the battery, residual value formation remains below its full potential.

BMS vs Analytics

Knowing the State of Health (SoH) of a lithium-ion battery in an all-electric vehicle is the fundamental basis for electric vehicle maintenance and battery warranty. Finding out the battery health at any point in a battery’s life is necessary for making operations profitable and safe, as well as enabling business models such as BaaS (battery as a service) or circular economy approaches.

Maximizing the value of battery energy storage systems

22 February 2022

Maximizing the value of battery energy storage systems

The use of energy storage systems is growing exponentially as costs decrease and deployment options increase.  Among currently available storage systems, batteries based on lithium-ion chemistry can provide a significant amount of this flexibility due to their high power and energy density and relatively low cost per unit of energy.  However, several challenges must be overcome to profitably operate a battery energy storage system (BESS) over its lifetime.  Battery analytics and smart algorithms can help provide insights to make the right decisions.  

TWAICE Vision Conference Report

TWAICE Vision Conference Report

Software is indispensable for a battery-driven future: Economic efficiency and sustainability in the battery sector are inseparably linked to software. Beginning of February battery software provider TWAICE, hosted a conference on exactly this topic. A conference report now highlights the main findings of the event.

International Battery Day

18 February 2022

International Battery Day

International Battery Day is celebrated every year on February 18, the birthday of Italian physicist Alessandro Volta, who introduced the first battery in 1801. Quite simple in design, his first attempts consisted of rudimentary objects: thin strips of copper, cardboard and zinc, separated by damp leather. Volta’s conducting element was – unbelievably – his own tongue. This Friday, the battery reaches the grand old age of 221 years. And with more car buyers now opting for electric, it seems a good opportunity to recognize what batteries have done for humankind, and the advantages their technology offers the mobility and energy spaces.

Impedance Research Paper

Impedance is an important characteristic of lithium-ion batteries since it directly influences their power capability. However, battery impedance is highly dependent on the operating condition and increases over the lifetime of the battery, due to degradation of the latter. Continuous tracking of the impedance can hence provide meaningful insights into the aging status of a battery.
