Battery products




History

In April 2015, the company unveiled its Powerwall home and Powerpack industrial battery packs, and received orders valued at $800 million within a week of the unveiling. The two Powerwall models included a 7 kWh (25 MJ) unit and a 10 kWh (36 MJ) unit, both with 2 kW (2.7 hp) continuous power. The Powerpacks were larger-scale configurations for industrial users in units of 100 kWh (360 MJ). The company planned to open source its patents for the entire range. In September, 2020, Tesela announced an increase in pricing to the Powerwall product line due to increased demand.

In October 2016, Tesla unveiled the Powerwall 2 with 5 kW (6.7 hp) continuous power and 13.5 kWh (49 MJ) capacity.

Initial cells were made by Panasonic. In 2017, production was shifted to Giga Nevada, where Tesla expected costs to drop by 30%.

Deployments

In September 2016, Tesla announced it had been chosen "through a competitive process" to supply Southern California Edison (SCE) with 20 MW (27,000 hp) power and 80 MWh (290 GJ) energy of battery storage. In May 2016, regulators had ordered SCE to invest in utility-scale battery systems to compensate local power supply after natural gas provider Southern California Gas leaked 1.6 million pounds (730 t) of methane into the atmosphere when a well ruptured at its Aliso Canyon Natural Gas Storage Facility, closing it permanently.clarification needed

In November 2016, American Samoa's island of Ta'u, with a population of approximately 600, was converted to a solar and battery microgrid from diesel-based energy generation. In 2018, two microgrid projects were built in Samoa on the main island of Upolu: one at the Fiaga power station and one at the Faleolo International Airport.

After Hurricane Maria in September 2017, Elon Musk offered to work with Puerto Rico's government in rebuilding the island's electrical grid. In October 2017, Tesla brought 700 solar panels to the "Hospital del Niño," where the batteries helped bring care back to 3,000 patients who needed constant care.

In June 2017, Hawaii's Kauai island received a 13 MW solar and 52 MWh battery installation. In July 2017, Tesla won a contract to install the world's biggest grid-scale lithium battery in South Australia by promising installation within 100 days. The Hornsdale Power Reserve with total power capacity of 100 MW (130,000 hp) and 129 MWh (460 GJ) was connected to the grid on December 1, 2017.

In July 2019, Tesla unveiled Megapack, a containerized battery product for utility-scale projects. Each Megapack comes fully assembled from the factory with up to 3 MWh (11 GJ) of storage and 1.5 MW (2,000 hp) of inverter capacity.

In February 2020, Pacific Gas and Electric Company received approval to deploy 449 Megapacks at the Moss Landing substation in Monterey County, California, to provide 182.5 MW of power and 730 MWh of energy storage capacity.clarification needed When operational in 2021, it will be the world's largest battery storage installation by a significant margin.

Tesla receives service revenue from customers after the initial vehicle purchase and reached almost $500 million in 2020 Q2. As of August 2020update, those services include: Vehicle servicing Charging Insurance Software upgrades Improved connectivity Future services which have been discussed include: Tesla network, Autopilot as a subscription, paying for a WiFi hotspot in the car, and the Tesla app store. Vehicle servicing For most vehicle manufacturers, only dealers can service (and sell) the cars, and the manufacturer receives no revenue from servicing cars. Tesla cars are not serviced through dealers. In 2016, Tesla recommended to have any Tesla car inspected every 12,500 miles or once a year, whichever comes first. In early 2019, the manual was changed to say: "your Tesla does not require annual maintenance and regular fluid changes," and instead it recommends periodic servicing of the brake fluid, air conditioning, tires and air filters. At the June 2018 shareholder ...
