鈥?What Tesla TSLA, -1.73% has built in the Nevada desert is impressive. Today it is a sprawling three-story red and grey structure the size of a dozen football fields that, when completed, aims to be the world鈥檚 biggest building. It is crammed top to bottom with automated machines, snaking assembly lines, engineering rooms, and 13,000 busy people working for Tesla and its Japanese partner. This is where half of the world鈥檚 electric-vehicle batteries are produced. Panasonic, occupying 30% of the building, produces the cells, 4,000 of which go into a pan beneath the floor of every Tesla Model 3 electric car. It鈥檚 a three-shift, 24-hour operation. Gigafactory is what South African-born Musk calls the machine that builds the machine. Density鈥攅fficient use of space 鈥?is driving down costs. Production begins on the third floor while finished panels emerge at the bottom. Each day, 1,000 car sets go by truck five hours to the Tesla car assembly plant in Fremont, Calif., on San Francisco Bay.
Plant manager Chris Lister, Tesla鈥檚 vice president of operations, calls the Gigafactory a self-contained, vertically integrated, manufacturing facility. The Gigafactory is a huge roll of the dice for the 15-year-old company that has yet to register an annual profit and which, analysts say, will lose money again this year. Many big investors have shorted Tesla stock, expecting the company to fail. Other big money investors and enthusiasts take the opposite view, saying Tesla is winning and leading the transition to sustainable energy. Engineering challenges at times create tension between Panasonic and Tesla. Musk is pushing for greater energy density in cells, which would boost vehicle range and increase power. Tesla has not yet selected Panasonic to produce cells for its vast plant under construction in China. In 2018 Tesla doubled the size of its fleet. But Musk and his deputies emphasize there is a huge untapped market. Electric cars account for only 1% of all cars on the road, and 60% of all electric vehicles are in China.
The new Tesla plant will be in Shanghai. Another production plant is planned for Europe, its location to be announced by the end of this year. Musk told shareholders that Tesla鈥檚 Model Y, a mid-size sport utility vehicle, will go into production next year. Both a semi-truck and a pickup 鈥?which Musk says will combine the attributes of a Ford F-150 and a Porsche 911鈥攁re in the works. Musk told shareholders that lowering the cost of batteries is critical. Boosting range and reducing charging time are huge engineering challenges. Vehicle range, said Musk, will soon expand to 400 miles (644 kilometers). The company dismisses reports that lithium is in short supply and says car sales currently exceed car production. Having put on weight over the past year ago and looking somewhat stressed, Musk said service and charging stations are the key to sales. On both counts, he said, Tesla is winning. In some markets Tesla personnel come to owners鈥?homes to change tires or do minor repairs. The number of supercharger stations is doubling. I traveled from the annual meeting in the Silicon Valley to Sparks, Nev., as a passenger in a friend鈥檚 Model 3. Acceleration and comfort were first class, even awesome. It is indeed a computer on wheels. But autopilot remains a work in progress. On the east coast of the U.S., Tesla naysayers are in control. Here on Tesla鈥檚 home ground, the enthusiasts and believers carry the day. Barry D. Wood, a veteran foreign correspondent, writes on economics markets, and world affairs.

This is unofficial documentation of the Tesla JSON API used by their iOS and Android apps. It features functionality to monitor and control their vehicle (Model S, Model X, and Model 3) and power (Powerwall) products. We currently have documentation for their vehicles, but always accept pull requests for improvements and additions. All requests require a User-Agent header with any value provided. For Tesla's sake, it's recommended you identify your application in some way using this header. Gives point-in-time data about the state of the vehicle and basic controls over certain functions of the vehicle. The state and command APIs loosely adhere to the REST standard, but differ in some crucial ways. As a result, you may not be able to use it with many REST tools and libraries out of the box. Streams in data about the car's telemetry at up to half second increments. The underlying protocol is simply a streaming HTTP API that provides JSON objects at regular intervals. A streaming command mode to control the automatic parking of HW1 (Autopilot v1) and HW2/HW2.5 (Autopilot v2) cars. This API uses a standard WebSocket that exchanges JSON objects to convey state information and issue commands during the Autopark session.
