Mullen announces battery results in late May after successful preconditioning tests

Written by Cláudio Afonso | | LinkedIn | Twitter

Mullen Automotive announced on Tuesday that Battery Innovation Center (BIC) in Indiana has completed the cell preconditioning in preparation for cell performance cycling. BIC will enter into high rate cycling as part of the performance-based cycling with those results forthcoming, the company added.

“I am pleased with the initial preconditioning results on our solid-state polymer battery cell and we’re progressing to the next stage of testing with BIC,” said David Michery, CEO and chairman of Mullen Automotive. “The battery has performed well and I’m looking forward to see finalized testing results from BIC later this month.”

It is expected that this technology, when scaled to the vehicle pack level, will deliver a 150-kilowatt hour, solid-state battery able to deliver over 600 miles of range on a full charge for the Mullen FIVE EV Crossover. In general, solid-state batteries offer higher energy density, faster charging time, smaller size and safety compared to traditional lithium-ion cells.


“We are in process with Mullen’s cell and are looking forward to continued testing with final results due later this month,” said Ben Wrightsman from Battery Innovation Center.

The Battery Innovation Center will continue to perform the following tests on Mullen’s solid-state polymer battery, with final results expected in late May 2022. 

Constant Current Discharge Test

Testing to determine the effective capacity of a test unit using very repeatable, standardized conditions.

Peak Power Test

The purpose of this test is to determine the sustained (30s) discharge power capability of a battery at 2/3 of its OCV at each of various depths of discharge (DOD).

Constant Power Discharge Test

The purpose of this testing is to perform a sequence of constant power discharge/charge cycles that define the voltage versus power behavior of a battery as a function of depth of discharge. This testing characterizes the ability of a battery to provide a sustained discharge over a range of power levels representative of electric vehicle applications. Constant power discharges are similar to constant speed vehicle operation in their effect on a battery.


Last week, the EV maker announced that will add Mullen FIVE RS on the second leg of the “Strikingly Different” U.S. test-drive tour. The electric vehicle maker also announced that new tour stops have been added for spring 2023. The Mullen FIVE RS is a high-performance EV featuring close to 1,100 horsepower, 0-60 mph in just 1.95 seconds, and a top speed of almost 200 mph.

Mullen is now extending the “Strikingly Different” tour to spring 2023 in an effort to increase test drive capacity, with the addition of more FIVE variants, including multiple Mullen FIVE RS vehicles. Initially, Mullen will start the national tour in October 2022 and embark on a 19-city journey across the U.S. over six weeks.

On Tuesday, Mullen had announced an upcoming 19-city national test drive tour for the Mullen FIVE starting in October. As part of its tour, Mullen will make stops across the U.S to provide FIVE reservation holders with the opportunity to test drive and experience the new Mullen FIVE EV Crossover in person.

The tour will start in Mullen’s home base, Southern California, and will cover major U.S. cities including: Los Angeles, San Diego, Las Vegas, Houston, Dallas, Memphis, Miami, Atlanta, Charlotte, Washington, Philadelphia, New York, Boston, Detroit, Chicago, Denver, Seattle, Portland, and San Francisco.

Mullen asks interested individuals who have not already done so to book their FIVE reservation here in order to secure a spot on the upcoming national tour. Further details and upcoming progress will be shared on Mullen’s social media platforms and with individuals who opt to stay connected here.

The company announced on Monday the filing of its ATVM loan application for the Mullen ONE EV Cargo Van Program with the U.S. Department of Energy. The application was filed on April 29, 2022. Mullen submitted its prequalification on April 25, and was invited by the Department of Energy to formally submit its loan application on April 29, 2022. Mullen submitted the loan application on April 29 at approximately 1:55 p.m. Pacific time.

Mullen recently teased via Twitter its Van production ahead of the first deliveries in Q2 2022, as announced by Mullen’s CEO on March 30. At the time, David Michery unveiled that a Fortune500 company is going to buy “a lot of these vehicles” with the official press release expected during the next weeks.

Last week, Mullen posted a new job vacancy on Indeed Platform looking for an Investor Relations Associate. The position is based in Brea, California, and the candidate will be responsible for engagement with the investing public, shareholders and financial professionals, the company said.

Mullen reached on April its highest level of Institutional Owners with 58 shareholders owning a total of 1,332,751 shares. Among the largest shareholders there’s: Cutler Group LP, Cetera Advisor Networks LLC, BlackRock Inc., Vanguard Group Inc, Cutler Group LP, Belvedere Trading LLC, and VTSMX.
