It appears as if Tesla is beginning to deliver cars with a built in Sentry Mode and Dashcam storage device. It currently functions that if a Tesla owner wants to use the Dashcam and Sentry Mode features, they must plug a USB storage device into the USB port in the car, and use a function on the screen of the car to format the USB drive to be compatible with the car. It makes sense that Tesla might want to include a storage device, as the feature was originally added to all cars via a software update and did not require any hardware changes. As of now, it appears that the included storage device is only being produced in cars made in the Shanghai factory, although this may trickle down into US made cars as we have seen with other features.
In 2018, Tesla received a large contract to build a massive battery pack in Australia which would store energy and help to reduce emissions as well as lower costs. After six months, it was evident that the battery pack was working as intended, as $17 million of the initial $60 million cost of building the battery pack was recouped. This week, tesla received another contract from Australia to build another Powerpack. While the first Powerpack only had a capacity of 100 MW, the new one will be able to store an impressive 300 MW of power. The new Powerpack will be used to service the Victoria to New South Wales interconnector in the event of an unexpected outage.
