Tesla Motors, Inc. is an American company that designs, manufactures, and sells electric cars and electric vehicle powertrain components. Tesla Motors is a public company that trades on the NASDAQ stock exchange under the symbol TSLA. In the first quarter of 2013, Tesla posted profits for the first time in its history.Tesla first gained widespread attention following their production of the Tesla Roadster, the first fully electric sports car. The company's second vehicle is the Model S, a fully electric luxury sedan, and its next two vehicles are the Models X and 3.Tesla also markets electric powertrain components, including lithium-ion battery packs to automakers including Daimler and Toyota. Its CEO, Elon Musk, has said that he envisions Tesla Motors as an independent automaker, aimed at eventually offering electric cars at prices affordable to the average consumer. Pricing for the Tesla Model 3 is expected to start at US$35,000 before any government incentives and deliveries are expected to begin by 2017. Wikipedia.

Patent
Tesla Motors | Date: 2017-02-08

A method includes: receiving information corresponding at least to (i) a state of charge of an energy storage of a vehicle, (ii) route information corresponding to a planned driving route for the vehicle, and (iii) a predicted driver characteristic; determining using the received information, and presenting to a driver of the vehicle, a first energy-versus-distance measure for the planned driving route; receiving a user input indicating a proposed change in at least the driver characteristics, and determining using the received information and the user input, and presenting to the driver, a second energy-versus-distance measure for the planned driving route that takes into account the proposed change.

An ultrasonic sensor assembly is placed against an inside surface of a panel for sensing objects on an opposite side of the panel and includes an ultrasonic sensor, a preload structure, a coupling element, and a damping material. The preload structure applies a preload on the ultrasonic sensor toward the inside surface of the panel. The coupling element interfaces between the ultrasonic sensor and the inside surface of the panel. The damping material is placed against the inside surface but not where the coupling element interfaces between the ultrasonic sensor and the inside surface. The coupling element may include a matrix material that is reinforced with a filler.

A heatsink with an internal cavity for liquid cooling includes: a first part having a first group of fins extending into the internal cavity; a second part attached to the first part so that the internal cavity is formed, the second part having a second group of fins that extend into the internal cavity and that are configured to fit among the first group of fins; an inlet into the internal cavity on at least one of the first and second parts; and an outlet from the internal cavity on at least one of the first and second parts.


A vehicle crush rail includes: a body configured to be at least partially crushed along an axis between first and second ends thereof, the body having a cross section profile that comprises first, second and third cells that are substantially square, wherein at least one of the first, second and third cells extends from the first end to the second end, wherein the first, second and third cells have respective initiators arranged according to a crush pattern for the crush rail.


An energy storage system includes: a host; energy storage modules; a plurality of nodes, each implemented at a corresponding one of the energy storage modules and configured to monitor and control that energy storage module; a communications and data transmission medium forming a loop from a first portion of the host and sequentially through the nodes to a second portion of the host; and in each of the nodes, first and second devices configured to perform at least partially redundant communication and data transmission functions using the communications and data transmission medium.


Patent
Tesla Motors | Date: 2016-11-22

An apparatus and method for identifying a presence of a short circuit in a battery pack. A fault-detection apparatus for a charging system that rapidly charges a collection of interconnected lithium ion battery cells, the safety system includes a data-acquisition system for receiving a set of data parameters from the collection while the charging system is actively charging the collection; a monitoring system evaluating the set of data parameters to identify a set of anomalous conditions; and a controller comparing the set of anomalous conditions against a set of predetermined profiles indicative of an internal short in one or more cells of the collection, the controller establishing an internal-short state for the collection when the comparing has a predetermined relationship to the set of predetermined profiles.

An energy storage system includes: a grid tie unit comprising at least one DC/AC converter; and multiple pods connected to the grid tie unit, each pod including: a number of cells; and a power electronics unit, wherein the cells are floating relative to the system and are galvanically isolated therefrom. The multiple pods may be organized into packs, with a pack including a thermal management system.


A system and method for mitigating the effects of a thermal event within a non-metal-air battery pack is provided in which the hot gas and material generated during the event is directed into the metal-air cells of a metal-air battery pack. The metal-air cells provide a large thermal mass for absorbing at least a portion of the thermal energy generated during the event before it is released to the ambient environment. As a result, the risks to vehicle passengers, bystanders, first responders and property are limited.
