Bollinger Motors has announced that Our Next Energy (ONE) will be supplying its modular, linkable Aries LFP (lithium iron phosphate) battery packs to power Bollinger’s all-electric commercial platforms and chassis cabs.

“ONE battery packs are ideal for our commercial trucks, giving our customers the range they need,” said Robert Bollinger, Founder and CEO of Bollinger Motors, which recently became a majority-owned company of Mullen Automotive, Inc. “The fact they’ll be built in the U.S. and in Michigan is a huge advantage for us going forward.”

Bollinger’s all-electric Class 4 through Class 6 chassis cabs are designed to meet commercial-customer needs in a segment that often requires large payloads, sufficient range, durability, and longevity.

“We are pleased to provide Bollinger commercial vehicles with industry-leading range, using our Aries LFP battery platform,” said Mujeeb Ijaz, Founder and CEO of ONE. “The Aries LFP chemistry contains no nickel and cobalt, offering superior durability and daily charging up to 100% without compromise.”

Bollinger had been developing its own batteries in-house.

“Halting development of our batteries in-house and teaming up with ONE is a win-win in both technological advancement and production logistics,” said Bryan Chambers, COO of Bollinger Motors. “We’ve not only advanced the quality of our product but moved our fleet delivery dates closer.”

Bollinger will first launch its Class 4 Chassis Cab, which is designed to hold one or two battery packs depending on the customer’s desired range needs. Class 5 platforms for walk-in van upfits will follow. The packs are expected to be available for Bollinger’s anticipated start of production in late 2023.

ONE is a Michigan-based energy storage company focused on battery technologies aimed at radically accelerating the adoption of electric vehicles. The company’s vision is to double the range of electric vehicles; use safer, more sustainable raw materials; and establish a localized supply chain. It says that this strategy will result in a reliable, cost-effective, and conflict-free supply chain.

The company says that the Aries battery is ideal for commercial and fleet vehicles. Using LFP chemistry that is free of nickel and cobalt, its structural architecture yields 76% cell-to-pack density to deliver the most energy-dense LFP battery in the market. Improved energy density means a smaller battery pack that takes up less space, allowing more cargo capacity. Its 108 cells in a scalable architecture allow for series and parallel configurations to meet customer power and energy needs. The intended service life is 3000 cycles at full depth of discharge. The pack has a liquid cooling loop thermal management system and integrated battery management system with redundant current measurement and overcharge protection.

Aries features an energy of 79 kW·h, a mass of 550 kg, and a volume of 285 L from dimensions of 1630 x 760 x 229 mm. Its GED is 144 W·h/kg and its VED is 287 W·h/L. Voltage is 348 V, with power of 120 kW peak and 79 kW continuous.
