Innovating battery technology for industrial and commercial vehicles


American Battery Solutions has established itself as a leader in the engineering, development and manufacturing of battery solutions. Here, they discuss the innovative battery technology that has made them experts in the field.

In the thirty years since the first lithium-ion cells were made commercially available. Battery technology has improved at an amazing pace. It is largely due to the commercialisation of lithium-ion batteries that our society has transitioned towards a truly mobile and global environment. Today, as the consumer electric vehicle is quickly becoming mainstream, this same technology is starting to be applied to a much wider range of applications, ranging from autonomous warehouse robots to construction and agriculture vehicles and heavy-duty trucks and buses. Supporting these underserved and emerging markets is the reason for which American Battery Solutions (ABS) was founded.

Battery DNA

ABS was founded in 2019, but its heritage dates back to the early 1980s. The ABS team is comprised of some of the best battery system experts and innovators in the industry, with decades of experience in designing, developing, and manufacturing advanced battery systems. Collectively, our team members have helped launch many of the most well-known and iconic electric vehicle battery programmes with OEM customers like General Motors, Fiat Chrysler, BMW, Daimler-Mercedes, and others. Backed by a substantial investment from KCK Group, a principal investment firm with offices in London, New York, the Bay Area of San Francisco, and Dubai, ABS had a massive head start by acquiring the manufacturing and battery testing assets from Robert Bosch Battery Systems in Michigan and Ohio. This acquisition included an established 170,000 ft2 manufacturing footprint in Springboro, Ohio and an engineering tech centre in Lake Orion, Michigan with state-of-the art cell, module and pack testing facilities. In the Michigan tech centre, we have a flexible manufacturing prototype and low volume module line that is capable of building with all three major cell form factors – cylindrical, prismatic, and pouch. ABS is a flexible manufacturing facility with the ability to manufacture multiple types of battery packs and modules on the same line. Our company uses the latest innovations in cell-to-cell joining technologies, including both laser and wire bonding techniques to make cell to cell connections. In Ohio, the ABS facility has over 15 years of zero parts per million (PPM) quality performance, having delivered over 60,000 battery packs. At the same, time the ABS facility has the capacity to build over 8GWh of cells, including 200,000 modules and 50,000 packs per year, with plenty of room to expand operations.

ABS has assembled a world-class team of dedicated and experienced engineers. This team brings a deep understanding of high voltage, automotive-grade battery systems and can take an idea from concept development and prototyping to testing and validation, straight through to high volume production. We are now leveraging our automotive experience to develop battery solutions to electrify the underserved market segments in transportation, motive industrial, and commercial sectors.

A leading battery technology innovator

Bringing this team of battery systems experts together is ABS’ founder, Chairman, and CEO, Subhash Dhar. Dhar has a long and distinguished career that has been entirely focused on developing the next generation of energy storage technologies. He was formerly CEO of XALT Energy, a leading manufacturer of lithium-ion batteries and founded lead acid battery systems maker, Energy Power Systems. Dhar served as Chairman and CEO of Envia Systems, a Bay Area company engaged in developing advanced lithium-ion battery technology; and served as Vice-Chairman of EnerDel and President of its parent Ener1 Inc. Prior to that, Dhar was the founding President of ECD-Ovonic Battery Company, from 1982 through 2003, where he developed and commercialised the nickel metal hydride (NiMh) battery technology which has powered today’s hybrid electric vehicles globally, and became the backbone of the Prius hybrid in the late 1990s.

Dhar’s experience extends beyond battery technology development as he has also set up business alliances and manufacturing operations in Japan, China, Europe, and the US. He has also been involved in many aspects of alternative and advanced technology including hydrogen generation, hydrogen storage, and fuel cells, serving as the President of Ovonic Fuel Cell Company, and CEO of Brazil-based Eletra Hybrid Bus, and as CEO of PlasmaDrive, a company engaged in the development of a novel combustion technology.

Bringing new, innovative products to market

ABS brings together all this experience and market knowledge to meet our customers’ needs for both custom and standardised pack designs. In the standardised family, ABS is launching a series of low-voltage and high-voltage battery pack solutions. The low-voltage ALLIANCE Intelligent Battery Series™ contains a unique set of features that allows it to be used in a wide variety of applications.

ALLIANCE modules come in 48V, and 24V options in 2kWh and 3kWh energy increments. The ALLIANCE series batteries pave the way for simple integration and drop-in replacement of lead-acid batteries, both in original OEM applications as well as an aftermarket replacement. They are designed to be handled like a lead-acid battery, without a need for ‘white glove’ treatment. The ALLIANCE products focus on those niche applications which tend to require lower power demands but still expect a very highly engineered solution. Products are used in applications ranging from autonomous warehouse robots to neighbourhood electric vehicles, construction and maintenance equipment such as scissor lifts and floor cleaners, and are even replacing diesel gensets on sail boats.
