BREA, Calif., April 21, 2022 (GLOBE NEWSWIRE) -- via InvestorWire -- Mullen Automotive, Inc. (NASDAQ: MULN) (“Mullen” or the “Company”), an emerging electric vehicle (“EV”) manufacturer, announces solid-state polymer battery testing with the Battery Innovation Center (BIC) in Indiana. BIC is focused on the rapid development, testing and commercialization of safe, reliable and lightweight energy storage systems for defense and commercial customers.

Started in 2013, Battery Innovation Center’s mission is focused on promoting the rapid development, testing, commercialization, and advanced learning of safe, reliable, high-performance, and lightweight energy storage systems for commercial, defense, academic partners and industry. BIC is a collaborative initiative designed to incorporate leadership from renowned universities, government agencies, and commercial enterprises.

The Battery Innovation Center will perform the following tests on Mullen’s solid-state polymer battery.

  • 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.

“We look forward to testing Mullen's cells capabilities and associated performance,” stated Seth McCoy, T&E Engineer from Battery Innovation Center in Indiana.

Previously Mullen highlighted test results conducted by EV Grid. Tom Gage, from EV Grid was recently featured on Risk On Podcast to discuss previously reported results. The test data collected by EV Grid showed an impressive outcome and future for solid-state batteries. The solid-state battery cell was rated at 300 Ah (ampere-hour), at test the battery yielded 343 Ah at 4.3 volts. It is expected that this technology, when scaled to the vehicle pack level, a 150-kilowatt hour solid-state battery can 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.
