California-headquartered green power solutions company Jackery is officially releasing the Explorer 1500 on April 5 – its largest solar generator yet. The company asked Electrek if we’d like to try it out, so Jackery sent me a review unit, and I happily put it to the test. Here’s what I found.

Tim Grewe, GM’s director of battery cell engineering and electrification strategy, held a virtual media conference today about the company’s EV battery strategy. It was a wide-ranging info session explaining the General Motors approach to chemistry, cell, and module design, and how EV batteries will be manufactured in high volume. “Categorically, we think that the pouch cell is the winner,” said Grewe.

The Korea Herald reports that pre-pandemic shortages of battery supply, which caused delays for European automakers, have been made worse by the global crisis. The situation became urgent enough for the Polish government to waive travel restrictions, allowing 200 LG Chem technicians to resume expansion of its battery gigafactory in Wroclaw.

Any legitimate EV development program starts with the batteries that make electric vehicles go. So when General Motors (GM) yesterday laid out its multi-brand, multi-segment EV strategy — for getting to 1 million EV sales per year asap — it presented the company’s flexible Ultium battery system as the key.

The adaptive charging method offered by software maker Qnovo ensures battery health for tens of millions of smartphones. Now the company wants to bring the same algorithms to EVs. Should we stop waiting for pie-in-the-sky breakthroughs in cell chemistry or solid-state EV batteries?

Too good to be true? Yes, probably, but that’s what a Tesla Model S owner on Craiglist is claiming. While we will have to disagree with the owner’s definition of “minor dents and dings”, it’s not impossible to imagine how this Model S would still be able to drive – though its salvage status is evidently still well-deserved. expand full story

For the most part, Tesla’s Gigafactory has looked the same from the outside since the beginning of the year. The first phase consists of 4 sections of about 475,000 square feet for a total of 1.9 million square feet. The final version of the building, which should be completed by the end of the decade, is expected to have 13 million square feet of manufacturing and work space. It should be enough to become the biggest building on earth by footprint and Tesla plans for the factory to produce at least as much battery capacity as the entire world production of li-ion cells.
Now we learn that Tesla is planning to add a new section to the plant with an estimated completion date by the end of the year, according a building permit recently issued to Tesla. expand full story

Last year, Tesla had some troubles with the way it calculated the power output of its electric vehicles. The company had to go in mediation with over hundred of its customers in Norway and eventually changed the advertised horsepowers of the Model S P85D from 691 hp to 463 hp.
The issues mostly revolved around defining electric power in terms of horsepower and the power output being dependent on the state of charge of the battery pack feeding the car’s two electric motors. The issues have been mostly resolved after Tesla updated its advertised numbers, but since the introduction of the Model X and the ‘Ludicrous mode’, things have been more complicated again… expand full story

‘Lithium’ battery capacity degradation is one of the main concerns of electric vehicle buyers and potential buyers. Since the resurgence of electric cars is relatively recent, meaningful long-term data on large battery packs is fairly rare. Only Tesla has battery packs with a capacity higher than 30 kWh on the road in any significant number and they only have been in operation for a few years (Roadster aside).
But a few Tesla owners have accumulated impressive mileage on their vehicles and the data provides an interesting look into potential battery capacity degradation. expand full story

The fine folks at GM have given us a shiny new (OK, 500 miles) electric blue 2017 Chevy Volt to test drive for the next week. I’m keeping a diary of my experiences every day here and will wrap up the week with my conclusions. (Day 2, Day 3-4, Conclusion/Wrapup)
