An Article by Mr. Venkat Rajaraman and Dr Mayank Vyas, Lithium Battery experts at Cygni Energy in EVreporter.

India is on the cusp of EV adoption. Battery failures can appear suddenly, and without warning, with the potential of severe injuries, product recalls, and loss of reputation. Hence the EV industry must invest in good battery design with advanced battery intelligence that can predict and prevent the user from unsafe batteries before they lead to any untoward incident. When it comes to Lithium-ion batteries, an ounce of prevention is far better than a pound of cure!

Battery & Data Analytics – Why Data Driven Approach is Critical to the Battery Industry?

September 2, 2021 No Comments

An Article by Mr. Venkat Rajaraman – Chief Executive Officer, Cygni Energy Pvt Ltd in JMK Research & Analytics,

The safety of Lithium-Ion battery is paramount and historical failures in smartphones and laptops give us valuable insight into the criticality of this issue. It is necessary to develop software intelligence to predict battery degradation, alert users to unsafe batteries and thus avoid any untoward incidents. Achieving this intelligence and 100% battery safety is a business priority now.

Then Versus Now: The traditional lead-acid battery is an electro-chemical device that is mostly unintelligent energy storage equipment. The battery intelligence is predominantly built around the Inverters or UPS that interface with the lead-acid battery. With the advent of the Lithium-Ion battery, this narrative has completely changed. With its Smart Battery Management System (BMS), the Li-Ion battery relies quite heavily on battery data for battery intelligence, analysis, and safety.

Million-Mile Battery For India: Is It A Reality Or A Pipe-dream?

August 3, 2021 No Comments

Opinion piece by Venkat Rajaraman – Chief Executive Officer, Cygni Energy Pvt Ltd

Prof Jeff Dahn’s (Dalhousie University, Canada) seminal paper, which got published after 3 years of extensive research, is touted as the “Benchmark for New Battery Technologies”. Though this paper does not describe any brand new chemistry, it is a composite of the industry’s best practices. The secret sauce is the electrolyte, with novel additives and other changes that can make the battery last longer. The paper also focuses on single crystal cathode (powder of cathode material made into a single crystal so that it doesn’t react with the surrounding electrolyte) as well as the best of cathode, anode and electrolyte materials to set the bar for achieving a million-mile battery.
