Beam Global granted new patent for intelligent battery thermal management system.

Beam Global has been granted a new patent by the US Patent Office for its Intelligent Battery Thermal Management (iBTM) system. The patent covers the company's technology that enables fast charging of lithium-ion batteries under extreme cold conditions using a heating element and Phase Change Composite material to regulate battery temperature. This innovation improves charging performance and battery health.

San Diego, CA — Beam Global (Nasdaq: BEEM), a leading provider of sustainable infrastructure solutions for the electrification of transportation and energy security, has been granted a new patent by the United States Patent Office. The patent covers the company's Intelligent Battery Thermal Management (iBTM) system, which enables fast charging of lithium-ion batteries under extreme cold conditions. The patent, titled "Fast Charging Batteries at Low Temperatures with Battery Pack Preheating," was granted as Patent No. US 12,431,549.

The iBTM technology integrates a heating element with the company's proprietary Phase Change Composite (PCC™) material to intelligently regulate battery temperature. Unlike conventional fast-charging solutions that rely heavily on complex active cooling systems, Beam Global's innovation dynamically manages charging rates, monitors battery health, and increases both the performance and lifecycle of lithium-ion batteries. Early simulations demonstrated a 10°C temperature increase in under three minutes, enabling safe, rapid charging in extreme cold conditions.

The iBTM system is integrated with Beam Global's smart battery management system and power electronics control, allowing for continuous, dynamic fast charging while accurately estimating the state of charge and state of health. Effective thermal management is essential to prevent lithium plating, solid electrolyte interphase breakdown, and other degradation reactions that typically occur during fast charging at low temperatures. The patented iBTM technology significantly enhances safety, extends cycle life, and provides a scalable, intelligent solution for electric mobility, defense, energy storage, and other applications where reliability and performance in all climates are essential.

Desmond Wheatley, CEO of Beam Global, commented on the significance of the patent, stating, "We continue to create new technology and intellectual property, which increases the value we deliver to the industry while also increasing barrier to entry for the competition. Our passive thermal management solution can now also provide active temperature control using the technology we have developed and protected with this patent. Being able to fast charge in lower temperatures expands the applications which batteries can support. Expanding those applications creates more opportunities for Beam Global’s energy storage solutions and as such creates new opportunities for sustainable and defendable growth."

Beam Global's iBTM technology is a significant advancement in the field of battery management, particularly for applications that require reliable performance in extreme cold conditions. The patented technology can have a substantial impact on the electric vehicle (EV) industry, as well as other sectors that rely on lithium-ion batteries for energy storage and power supply. The company's continued innovation and intellectual property development position it as a key player in the clean energy and transportation sectors.
