Abstract: A system for determining a state-of-charge (SOC) of an electric vehicle includes one or more sensors supportable within the electric vehicle and a processor. The one or more sensors are configured to determine one or more values related to the electric vehicle, respectively. Each value of the one or more values represents a state of the electric vehicle or a state of an environment in which the electric vehicle is located. The processor is configured to determine an SOC of the electric vehicle based on the one or more determined values related to the electric vehicle. The device also includes a wireless communication interface configured to transmit data representative of the determined SOC of the electric vehicle and/or data representative of the one or more values related to the electric vehicle to the processor or to another processor.

Abstract: A system for determining a state-of-charge (SOC) of an electric vehicle includes a housing that is supportable within the electric vehicle, one or more sensors supported by the housing, and a processor. The one or more sensors are configured to determine one or more values related to the electric vehicle, respectively. Each value of the one or more values represents a state of the electric vehicle or a state of an environment in which the electric vehicle is located. The processor is configured to estimate an SOC of the electric vehicle based on the one or more determined values related to the electric vehicle. The device also includes a wireless communication interface configured to transmit data representative of the estimated SOC of the electric vehicle and/or data representative of the one or more values related to the electric vehicle to the processor or to another processor.

Abstract: A dual rate force transducer is disclosed. A spring is machined to have a first spring portion with a first spring rate, a second spring portion with a second spring rate, and a platen between the spring portions. A pair of flanges are affixed to the distal ends of the spring portions. At least one sensor is affixed to one of the flanges, and at least one other sensor is affixed to another one of the flanges. Mounting hardware is used to couple the springs, flanges and platen together, including at least one mechanical stop to limit displacement of the spring.
