Mullen to Begin Testing Solid-State Polymer Battery Technology in Test Vehicles on US Roads

Mullen Automotive Inc, a US-based electric vehicle (EV) manufacturer, has announced the integration of solid-state polymer battery technology into the company's commercial Class 1 EV cargo van program. It will begin testing this technology in its Class 1 EV cargo vans starting in Q4 2023.

Currently, the Mullen Class 1 EV cargo van features a 46-killowatt lithium-ion battery pack with a 110-mile range.

It is expected that the solid-state polymer technology will deliver more than 200 miles of range on a full charge for the Mullen Class 1 EV cargo van.

Mullen will use The Linghang Guochuang Holding Group Co., Ltd's next-generation LH solid-state battery technology,

In general, solid-state batteries offer higher energy density, faster charging time, smaller size, and better safety compared to traditional lithium-ion cells. 

David Michery, CEO and chairman of Mullen Automotive., says: “The continued development of solid-state polymer batteries into our portfolio of vehicles, starting with the Class 1 EV cargo van, demonstrates our continued commitment to improving battery efficiency and overall vehicle performance." 

John Schwegman, chief commercial officer of Mullen Automotive, adds: “Electric vehicles for fleet applications are proven to reduce maintenance and operating costs. Offering a higher-range battery option at a similar cost structure would significantly increase the number of use cases and routes in which commercial customers could deploy EVs.”

We are pleased to be the first company in the U.S. to implement LH solid-state polymer battery technology in a commercial vehicle in conjunction with Mullen Automotive,” comments Yao Wang, general manager, new energy power business department, Linghang Guochuang Holding Group Co., Ltd.

Mullen's EV development portfolio includes the Mullen FIVE EV Crossover, Mullen I-GO Commercial Urban Delivery EV, Mullen Commercial Class 1-3 EVs, and Bollinger Motors, which features both the B1 and B2 electric SUV trucks and Class 4-6 commercial offerings.
