I think the car gives plenty of warning if the main battery is running low but they do seem to have overlooked the little 12V one that runs all the systems......
Aiui all EVs have these secondary batteries so I expect there have been other such instances......

If proven, it looks like a good fit for a range-extender: small, light, etc..
However it does seem very similar to the Wankel concept....

I scan-read a review of LR's upgraded PHEV version of the Disco Sport.
It is powered by a 1.5 litre, 3-cylinder petrol engine driving the front wheels with an electric motor driving the rears.

So it only has 4-wheel drive when there is charge in the battery to drive the rear axle.

That could get tricky. Say you've been driving fast for far enough to leave the battery at or close to minimum and then face some uphill driving in slippery conditions. Traction could be a serious problem.
A family trip to, say, an Alpine ski resort could become a real challenge. The car would be heavily-loaded and the climbs up to resorts are typically steep with no downhill sections to charge the battery. That dinky engine would be screaming its nuts off, dragging 2.5+ tons up the mountain. And 2-wheel drive in snow could make things very interesting.

I wonder how many buyers are aware that, despite the badge, the car does not have permanent 4-wheel drive?

What goes down.....
"Solar module prices have risen 18% since the start of the year after falling by 90% over the previous decade. The reversal, fueled by a quadrupling in the cost of the key raw material polysilicon, threatens to delay projects and slow uptake of solar power just as several major governments are finally throwing their weight behind it in an effort to slow climate change." (Bloomberg)

On that LR PHEV, apparently the rear wheels can always be powered, even when the battery is drained, because the engine's integrated starter/generator can supply electricity. However I have not found any info on the output of the s/g unit; what I have read suggests it will not be anywhere near the rating of the motor. Customer experience will probably shed some light in due course.

So a campaign group took an electric coach down to Cornwall but then.....

From a GWPF post quoting Newsweek, California is struggling with power demand so is talking of pushing folk to charge their EVs during the day when power from solar and wind is usually more plentiful. Only problem.....daytime is when people are likely to want to use their cars. Could be a market for very long power cables?
Full post:
Meanwhile, California’s grid is so inadequate that it can’t effectively charge the tiny number of electric cars already on the road. Newsweek reports:
"As temperatures hit triple digits during California’s heat wave last week, the state’s power grid operators encouraged residents to relieve pressure on the grid by charging their electric vehicles before the peak energy use times of day.... “Now is the perfect time to do a load of laundry,” the state’s Flex Alert Twitter account posted on June 18. “Remember to use major appliances, charge cars and devices before #FlexAlert begins at 6 p.m. today.”
It is characteristic of some especially poor or war-torn third-world countries that electricity is available only intermittently during the day. California, welcome to the third world.
"Patty Monahan, the lead commissioner on transportation at the California Energy Commission, told Newsweek last month that the times of day Californians choose to charge their electric vehicles will be important in keeping the power grid balanced as reliance on electric vehicles grows...

Matthew Moniot, a researcher with the National Renewable Energy Laboratory, said during a recent interview with Newsweek that electric vehicle owners now mostly charge their vehicles at night, but that will likely have to change so that more drivers are charging while energy production levels are higher."
There is a reason why EV owners charge their cars at night. It is because that is when they are not driving them. The problem is inherent, since the Sun doesn’t shine at night and winds tend to die down at night, as well.
There is no real solution to the problem when EVs represent two percent of the cars on the road, let alone in the hypothetical world where they are 100 percent.
"Increased reliance on solar and wind energy will present a “tricky problem” regarding “how much can we move what’s currently overnight charging to be during the daytime hours, when generation may be more excessive,” Moniot said. “The key is flexibility,” he added."
Sure. Drive your car at night, and charge it during the day.
