Bollinger's New Battery Technology Will Be A Game Changer

Electric Vehicles / Comments

This innovative design will help extend the battery life in Bollinger's electric vehicles.

Bollinger got our attention when it unveiled the B1 and B2 electric pickup and SUV. Compared to rivals like the Rivian R1T, Tesla Cybertruck, and the upcoming Ford F-150, the B1 and B2 sport boxy, more utilitarian designs akin to a vintage Land Rover and are designed to get dirty.

The initial specifications suggest the B1 will be even more capable off-road than the new Land Rover Defender. Each model will be underpinned by the company's in-house developed E-Chassis electric platform containing a lithium-ion battery pack available in several sizes. Previewed by a patent filed with the United States Patent and Trademark Office, Bollinger's battery pack will have an innovative design that saves space and provides better cooling.

"The heart of every EV is the battery, so it was crucial for us to develop our own battery pack in-house," CEO Robert Bollinger explained. "Our engineering team has created a pack with high-strength structural properties, exemplary cooling features, and state-of-the-art software."

Bollinger's battery pack features modules in 35 kWh strings that can be connected in series or parallel, allowing for a variety of sizes and configurations. The battery pack will be offered in 35, 70, 105, 140, 175 kWh, and higher sizes, with many capable of both 350V and 700V configurations.

When the B1 and B2 were unveiled, Bollinger claimed the 120kWh battery pack will provide a range of 200 miles, while four electric motors will produce a combined 614 horsepower and 668 lb-ft of torque.

Using a fast-charging system, the 120-kWh battery pack can be fully charged in 75 minutes. The battery modules are connected to both sides of a symmetrical and structural I-beam with channels that extract heat away to keep the modules cool.

Developed in-house, Bollinger's Battery Management System software can also monitor the voltage, current, and temperature and work with other control units in the vehicle to increase the efficiency and extend the battery life. It can also detect and isolate faults to keep the system running safely. As well as the B1 and B2, Bollinger's streamlined battery pack will support heavier vehicles such as medium-duty trucks, agricultural, and construction equipment.

Bollinger plans to manufacture battery packs for its own models in 2021 and will also make them "commercially available for standalone applications."
