Battery pack

Tesla builds its own battery packs, but imports the several thousands battery cells needed per pack from suppliers, mainly Panasonic. The automaker is heavily investing to change that by building the Gigafactory, in partnership with Panasonic, to manufacture both the cells and battery packs in the Nevada desert east of Reno.

But the planned output of the factory is 35 GWh in battery cells and 50 GWh in battery packs, meaning the Gigafactory will need to import 15 GWh of battery cells. Tesla already confirmed its intention to source the cells from more than one suppliers “potentially including Panasonic”, and today we learn through a new report from Asia Nikkei that the company is reportedly in the final stages of negotiations with LG Chem.

The so-called “poaching war” for top automotive engineering talent between Tesla and Apple gathered quite a few headlines in the past months, especially after Tesla CEO Elon Musk called the Cupertino company the “Tesla Graveyard” for hiring people he claimed were “fired” by the company. But after looking closer into the recent hires between the two companies, it looks like Tesla has little to fear from Apple’s recruiting effort, at least if we compare it to Faraday Future’s.

Faraday Future took a small step out of ‘stealth mode’ earlier this summer to announce that it is looking for a location for a manufacturing facility to build an electric vehicle. In the months since, the 1-year old startup ramped up its hiring effort and now has over 400 employees with an impressive percentage coming from Tesla.

Tesla Motors, SpaceX and SolarCity – three companies influenced by Elon Musk – are currently on a massive hiring spree around the US. They already have a combined headcount of over 32,000 employees and the total is set to increase significantly in the coming months. We learned that Musk’s companies are holding joined private recruiting events, the latest of which held last weekend at SpaceX’s headquarters in Hawthorne, California.

Recruiters from each company select students recommended through university programs and invite them to the relatively secretive events to interview with SolarCity, SpaceX or Tesla.

This year electronics and auto parts giant Bosch has been heavily investing the auto industry’s transition to electric powertrain. Earlier this summer, Bosch bought the solid-state battery start-up Seeo Inc. and has since been sparsely revealing details about its plan to bring new battery technologies to market by 2020.

During the company’s recent inauguration of its Renningen research campus, head of battery technology R&D Dr. Thorsten Ochs revealed more information about the company’s goals for Seeo’s solid-state battery. The Germany-based part maker is aiming for a 50 kWh pack to weight only 190 kg.

As we recently mentioned, there’s been some confusion in the media about the price of the Tesla Model X. The confusion even spread to Wall Street where analysts have been reducing their target price on Tesla’s stock because of the expensive $132,000 price tag circulating in the media.

To be clear, $132,000 is the starting price of the Signature Model X which is already sold out. The Signature comes standard with the performance package (P90D) and several options which increase the price. For example, a maxed out Tesla Model S cost $138,000, but the base version  starts at $70,000. Yesterday Elon Musk confirmed at a Vanity Fair conference that the Model X will have a similar price structure starting next year (when Tesla can actually catch up to demand).

SolarCity announced today a new project with the Temecula Valley Unified School District to install 6 MW of solar energy capacity and 2.6 MWh of energy storage at a total of 19 schools in the district. The solar installations will mainly consist of carports using the company’s ZS Beam system (see picture above).

Charging is still the primary concern of any new potential electric vehicle buyer. They want to know where they can charge the car and how long it takes. Now with the numerous charging standards and the difference between car models and battery pack sizes, it can be a difficult landscape to navigate. The bigger the battery pack, the longer it takes to charge, but at the same time, you can get an higher charging rate.

Netherlands-based charging station start-up Fastned is making the (safe) bet that battery packs will soon get bigger and, more importantly, they will be able to take higher charge rates.

Casey Spencer, a Tesla Model S owner, set a new record for the longest distance traveled on a single charge in a Model S by driving 550.3 miles in 26 hours. Spencer surpassed Bjorn Nyland’s record of 452.8 miles set just last month. Although Nyland used a Model S P85D, while Spencer used his Model S 85D.

A video posted to Youtube today gives us the most recent look at Tesla’s battery factory under-construction in the Nevada desert. For the first time we see the walls of what could become the biggest building on earth. In the latest drone fly-by video, we could only see the barebone steel structure.

The company plans to significantly reduce the cost of batteries through economy of scale by producing 50 GWh of battery packs at the ‘Gigafactory’. Tesla expects to produce the first battery packs at the factory during the first quarter of 2016.

Tesla Motors released more information about the Roadster battery upgrade in an email sent to owners today. The new battery pack will have 40% more energy than the previous version, but it will be heavier therefore allowing a 35% increase in range. The pack will be hand-built at low volume and Tesla doesn’t aim at making a profit on the upgrade, which will cost $29,000 including labor.
