What changed

The United States Patent and Trademark Office (USPTO) has granted patent US12586835B2 to Volvo Truck Corporation for an energy storage system (ESS) flooding control method. The patent describes a control unit that detects critical conditions within an ESS and activates a flooding mechanism using fluid from a reservoir. The system aims to submerge the ESS to a level where the critical condition is mitigated.

This patent grant is primarily an intellectual property development for Volvo and does not impose new regulatory obligations on other entities. However, it signifies innovation in battery safety and thermal management, which may influence future industry standards or practices in electric vehicle and energy storage manufacturing. Compliance officers in the automotive and energy storage sectors should be aware of this technological advancement as it relates to product safety and design.

Abstract

A method performed by a control unit for controlling flooding of at least part of an energy storage space. The energy storage space comprises at least one Energy Storage System, ESS. The control unit detects that a critical condition associated with the at least one ESS is present. When the critical condition has been detected, the control unit initiates flooding of at least part of the energy storage space with a fluid from a reservoir. The control unit controls the flooding of the energy storage space such that the at least one ESS is submersed to a submersion level where the critical condition is no longer present.
