Battery simulation models

Mercedes-Benz is just the latest in a long line of companies committing to an all-electric product line-up. Central to this transition in the mobility space is the lithium-ion battery. Outside the automotive industry, these batteries are already a key technology. But while the battery is a powerful enabler, it can also be an Achilles’ heel. We talked to TWAICE battery modeling engineer Goku, who explains the most pressing issues.

Predictive battery analytics in the energy sector

Battery storage is a fundamental part of the energy sector. Batteries, however, are complex systems. Deriving the maximum profit from them without incurring any additional risk is the overarching goal of most energy operators. This is where battery analytics can help.

E-Bus Battery Optimization

The e-bus market is already moving fast in 2021. Established bus manufacturers are setting the pace. E-bus manufacturers are currently facing a plethora of questions and uncertainties. Major challenges include the development of the highly complex batteries, warranty management, sustainable fleet management and the issue of battery reuse and recycling.

E-Bus Fleet Management

The e-bus market is developing rapidly in 2021. Pollution in cities and towns is the often cited reason for the transition from old diesel machines to clean e-buses. But many transport companies are still concerned, their primary worry being the expense of the batteries.

Electric Vehicle Recalls

Numerous recent recalls showed how much risk is associated with the most important competent of the emission-free mobility. The battery is a highly complex piece of technology that must be tightly analyzed not only during the development but also during operation.

LFP in energy storage

Lithium-ion batteries play an essential role in the transition to renewable energies and in generating electricity from more reliable and sustainable technologies. Even though NMC is currently the most mature existing technology, and it is therefore widely used, especially in the automotive industry, LFP technology is increasing in popularity due to cost and safety advantages.

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

Batteries are complex systems whose operation is determined by a variety of factors, making long term projections a challenge. However, it is possible to understand the future conduct of these systems by building models that mimic their behavior and leverage the computational power to perform the required calculations.

Streamlining e-bus warranty discussions

The automotive sector’s transition to green mobility is challenging the bus operators across the world. That was the case of a major operator of electric buses in the Netherlands, who reached out to ViriCiti and TWAICE regarding our Battery Health Solution to integrate data-driven decision making focused on batteries, to avoid timely and costly warranty discussions.

Modeling capacity fade of li-ion batteries

Aging models are fundamental tools to optimize the application of lithium-ion batteries. In this work, we show that the CAP-method models capacity fade more accurately when applied to dynamic cyclic aging tests with periodically changing mean state-of-charge, depth-of-discharge, ambient temperature and discharge rates for a commercial NCA cell with a silicon-doped graphite anode.

Combining EIS and time-domain data

This work proposes a method to combine time-domain and frequency-domain measurement data for parameterization of RC elements by exploiting the full potential of the distribution of relaxation times (DRT).

Quantifiability of Cell-to-Cell Variations

Motivated by the question of why impedance variation is consistently reported to be higher than the variation of other parameters, we show that measuring inherent parameter variations caused by production tolerances is superimposed by effects of an imperfect measurement setup.
