A Tesla Motors patent application filed earlier this year shows the company's interest in a hybrid battery pack using lithium ion and metal-air batteries. The patent is titled "Electric Vehicle Extended Range Hybrid Battery Pack System." With a publication date of July this year, the patent describes a battery pack that would make use of a standard lithium ion battery along with a metal-air battery pack. Such a system could spur adoption of electric cars, based on the premise that one car, fitted with combined battery types, may ease concerns about how far one can expect to travel on a single charge. The patent application focuses on a hybrid battery pack that could ease those concerns and support Tesla's future success.
The patent applicant, Tesla Motors of Palo Alto, states that this is a “method of extending driving range of an electric vehicle.” The invention that Tesla has in mind “provides a power source comprised of a first battery pack (e.g., a non-metal-air battery pack) and a second battery pack (e.g., a metal-air battery pack), wherein the second battery pack is only used as required by the state-of-charge (SOC) of the first battery pack or as a result of the user selecting an extended range mode of operation.”
Interpretive reports on the patent this week note that this could be a system that makes use of two different types of batteries to make sure an electric car could provide greater range at a reasonable cost. The lithium-ion battery would carry performance most of the time while the metal-air pack would serve the car for long-distance trips. The metal-air batteries would be an especially suitable choice for Tesla to deploy for longer-distance driving because of cost. Metal-air batteries would be cheaper to produce and in turn Tesla could afford to keep the car prices down when turning out long-range EVs.
