from chemistry to pack
An update on the Rivian R2 battery pack, now we have more information and more hard data. Trouble is the 2024 Investor Day R2 data left out a lot of the detail and the CEO updates in 2025 (Rivian R2 Pack – 2025 Update) were a little bit confusing. Time to again see if we … Read more
The 2025 Porsche Cayenne EV Battery is an interesting design that uses LG Chem pouch cells and as such sticks with a modular based design. The power electronics are arranged in an enclosure that is fixed to the top rear of the pack, a very traditional approach. Metrics This post has been built based on … Read more
My first new car (ever) is an EV Renault Megane E-Tech Techno 220cp 60 kWh. EV Details: My Experience Total km till Date: 573 km. I only did few trips near the house before one long trip (details below). I have solar panels at home so I am charging Type 1 with maximum 2.3 kW … Read more
Yanti Innovative Electromotive Solutions Pvt Ltd Abstract A module at 78% state-of-health (SoH) is scrapped as end-of-life; after reconditioning, it powers a stationary storage for three more years. Another at 82% SoH fails weeks into revival. Conventional metrics cannot explain the difference. Field analysis of >1,000 EV modules across platforms reveals that recoverability the probability … Read more
1. Introduction Ola Electric has rapidly positioned itself as one of the most influential players in India’s electric two-wheeler revolution. Beyond the scooters themselves, a critical pillar of Ola’s strategy is its in-house battery technology, which serves as the backbone of its product roadmap and cost leadership ambitions. The company has invested heavily in vertical … Read more
Is it necessary to clean battery terminals before welding? This is a common question for those focused on battery production processes. Author Jerry Wan Laser cleaning of terminals is a critical step in the assembly of battery modules. It effectively removes surface impurities and creates optimal conditions for laser welding, which in turn enhances product … Read more
through Design, Thermal Management, and Revival Techniques Abstract Battery life (longevity) is a cornerstone of electric vehicle (EV) sustainability, particularly in fleet-heavy regions like India, where high usage, climate stress, and inconsistent charging behaviours accelerate degradation. At Yanti Innovative Electromotive Solutions, we focus on a revival-first approach to extend the functional life of EV batteries. … Read more
AION Engineering INC In lithium-ion battery technology, optimizing cell performance and safety requires careful consideration of multiple parameters. Among these, the cut-off voltage is critical for balancing energy density and ensuring cell longevity and stability. While cathode chemistry often guides cell classification, variations in anode materials significantly impact the appropriate cut-off voltage setting. Influence of … Read more
During the charge / discharge the cathode and anode undergo an expansion and contraction. As you charge a cell it expands, when you discharge a cell it contracts and as the cell ages over its lifetime we see a continuing cell expansion. Thus the cell expansion can be divided into: This expansion and contraction puts … Read more
The energy storage industry just crossed another important milestone. CATL has launched the world’s first 9MWh energy storage system built for mass production. The system is called the TENER Stack. This isn’t simply a larger container. Rather than building a single oversized unit that would trigger regulatory and logistical issues, CATL introduced a modular “two-in-one” … Read more
