EV startup Ample today announced the rollout of its new modular battery swapping technology. A fully autonomous station deploys robots to remove and replace modules from an electric vehicle containing Ample’s modular battery architecture. These swapping stations are currently operational in California’s Bay Area.

With the rise and fall of battery-swap company Better Place in 2013, the prospect of mass-scale swappable EV battery packs in the US fell by the wayside. Tesla abandoned the idea a few years later. The big problem (among many) was a lack of common battery standards across multiple automakers. Battery packs need to be the same size and shape. That’s an issue that could be solved in China, where strong state control can dictate standards.

Profitable production of electric vehicles is highly important. Our capitalist society revolves around profitability and therefore, if electric vehicles are to prevail over gas-powered cars, they need to be profitable to manufacture in mass.

A new study published this month by McKinsey & Company and embedded below looks into how automakers can move past producing EVs as compliance cars and “drive electrified vehicle sales and profitability”. Unsurprisingly, it describes battery economics as an important barrier to profitability and though the research firm sees a path to automakers making a profit selling electric vehicles as battery costs fall, it doesn’t see that happening for “the next two to three product cycles” – or between 2025 and 2030. expand full story

Back in May, we shared a report from German newspaper Handelsblatt, which has often produced reliable insider reports on the German auto industry, citing insider sources saying that Volkswagen was about to present to its board of directors a plan to build a ‘multi-billion euro battery factory’.

In a new interview with the same newspaper this week, VW CEO Matthias Müller denies plans for the giant electric vehicle battery factory. expand full story

As always, a healthy dose of skepticism is important when it comes to an alleged “battery breakthrough”. Those announcements are being made every 2-3 months over the last decade and rarely anything comes to it, but at least we can always rely on the 5-8% annual incremental improvements in li-ion battery capacity. It’s not a “breakthrough” or doubling of capacity, but it adds up.

Now it’s time for another MIT spinout, after the defunct A123 Systems, to claim to have created the next battery breakthrough with an anode-free li-metal battery that could achieve an energy density of up to 500 Wh/kg – about twice the capacity of the current cells found in Tesla’s vehicles for example. expand full story

The Tesla Model 3’s $35,000 price tag will be enabled in part due to a significant reduction in battery cost through the automaker’s partnership with Panasonic on the Gigafactory in Nevada. While Tesla owns and operates the giant battery factory, Panasonic is still in charge of battery cell production at the plant, which Tesla then uses to make battery packs for its vehicles.

With the strong demand for Tesla’s vehicles, Panasonic now says that it expects its battery sales to double within the next 3 years – or after the first full planned year of Model 3 production. expand full story
