We haven’t even come close to seeing what sort of design Chinese electronics manufacturing behemoth Xiaomi intends to deliver under its young automotive division, but we may have a better idea of what level of power it may be packing. A recent image has surfaced that appears to showcase Xiaomi’s EV battery specs, hinting at an 800-volt platform housing over 100 kWh of battery power.
If you’ve never heard of Xiaomi Automotive, that’s understandable considering the young EV division was announced a mere two years ago and has yet to reveal its first model. Xiaomi Corporation on the other hand, is the second-largest manufacturer of smartphones on the planet which has led the company to expand into additional products like TVs, unmanned aerial vehicles, and even an ecosystem of Xiaomi Smart Home products.
We’ve followed Xiaomi Automotive as it set up its headquarters in Beijing where it intends to eventually produce up to 300,000 vehicles per year. There hasn’t been any mention of EV battery production, but given Xiaomi’s expertise in the technology, developing its own platform makes the most sense and was all but confirmed after rumors stirred about the new arm seeking co-branded EVs with BAIC in China.
Last we heard this past March, Xiaomi was once again taking EV development into its own hands and the progress of its new business had already “exceeded expectations.” This update followed some alleged leaked images of Xiaomi Auto’s camo’d sedan, which is expected to begin scaled production in the first half of 2024.
Most recently, another alleged leaked image, this time of a battery, suggests that Xiaomi Automotive is in fact progressing quickly and apparently knows what it’s doing – especially if it can deliver this platform at the price it originally promised.
Xiaomi battery image appears legit, packs 101 kWh
The battery image seen above, recently posted by MetaAuto on Weibo, features the Xiaomi logo and lists the following specifications:
Model Name: A1310C
Part Number: P000000367001
Manufacturer Code: F47832
Lithium-Ion Chemistry
726.7V
139 Ah
101 kWh
642 kg (1,415 lbs)
The voltage listed suggests the battery will deliver 800V fast charging to future Xiaomi EV drivers, and over 100 kWh of capacity is encouraging for a sedan when you think of the range that may be able to deliver. Other users on Weibo have pointed out that the battery modules should be lithium ternary, but there’s no way to confirm that without Xiaomi sharing details directly.
Xiaomi Automotive has not confirmed that this is in fact one of its EV battery packs. Right now, all we know is that the company is planning to deliver a sedan next year equipped with LiDAR supplied by Hesai Technology out of Palo Alto, California. The flagship EV is expected to start at a price around 300,000 yuan (~$43,100) – a steal for an 800V platform and LiDAR if it happens.
We also know that Xiaomi has been testing its own self-driving EV technology, which it says is aiming to be top-tier in the industry by next year. Let’s start with delivering an actual EV first, guys. That should happen sometime in the first half of 2024, and we are almost certain to learn more about Xiaomi’s EV, its battery packs and all the pertinent specs before then. Stay tuned.

After years of waiting and many falsestarts, Formula E is finally going to debut its mid-race charging system, which will give cars a quick boost of energy charging at a rate much faster than current road cars can.
For years now, we’ve been hearing about FIA plans to introduce charging stops to electric racing.
In gas car racing, some series allow mid-race fueling and some don’t. The World Endurance Championship, which runs the 24 Hours of Le Mans, obviously needs to fill up several times during the race. But Formula 1, which hosts shorter races, eliminated mid-race fueling in 2010.
But the FIA already had one electric racing series, Formula E, which had debuted in 2014. At the time, each driver had two cars, and would swap mid-race to a fresh car with new batteries.
Battery-swapping had been considered, but it would be too complicated to set up at temporary race facilities in city downtown areas, as many Formula E tracks are.
Then, in 2018, Formula E debuted a new “Gen 2” car which had a big enough battery not to need a charge mid-race, and later a “Gen 3” car in 2022, which had much stronger regenerative braking, capable of 600kW of braking power. Gen 3 also has an “Attack Mode” feature that lets cars unlock additional power for a short period each race, adding to strategy and mixing up the race order.
The issues involved building the charging system in temporary facilities and ensuring safety of the system (and of pit stops in general, which is always a concern when cars are driving rapidly near people). But after winter testing prior to this season, Formula E now says the system is ready to go.
So, once again, Formula E is ready to announce that mid-race charging is definitely, totally, positively, 100% certain at the upcoming Jeddah E-Prix, on February 14-15 in Jeddah, Saudi Arabia.
Formula E thinks that proving this high-power charging technology could help road cars to charge more quickly, which could have myriad benefits for electric cars in general.
The series is calling the system “Pit Boost,” and it will consist of a 34-second pit stop that provides around 10% additional charge to the cars (about 4kWh). While 10% isn’t a lot, 34 seconds is also not a lot of time. For comparison, one of the fastest-charging cars out there, the Ioniq 5, can charge from 10-80% in 18 minutes, which means 10% charge takes 2.5 minutes – five times as long as Formula E cars will manage the feat.
The stop will be mandatory for all drivers to take at some point in the race, and will mean new strategy options for drivers. Taking the stop means getting more energy, which means that your car won’t have to do as much energy saving to get to the end of the race – but it also means giving up your position on track, which can be hard to get back if you do it late in the race.
However, we’ve never seen it happen before, so it will be interesting to see what kind of strategic options develop.
If you’re interested in seeing how it turns out, tune in to the Jeddah E-Prix on February 14-15 to see what happens. It’s a doubleheader race weekend, with night races both on Saturday and Sunday, February 14-15, at 5pm UTC, 9am PST, 12pm EST, and 8pm local time. You can check out how to watch the race in your area by going to Formula E’s “Ways to Watch” section. In the US, Roku should be the most reliable way to watch.

JackRabbit, the maker of pint-sized electric microbikes, is back with a new product designed to quickly recharge their batteries from pure, uncut photons mainlined into an e-bike directly from the sun. In true independent charging form, the Solar Charging Kit from JackRabbit keeps riders rolling even when there’s not a convenient AC outlet in sight.
Unveiled this week, the Solar Charging Kit consists of a single folding solar panel and a tiny voltage converter that is configured to output 42.0V, which is the exact voltage required by JackRabbit’s little e-bike batteries. There’s also an added USB-A and a USB-C charging port for powering other devices in addition to charging JackRabbit batteries.
“This Solar Charging Kit plugs directly into your bike,” explained the company, “letting you recharge without needing an outlet, but with a speed comparable to the charger that comes with the OG/OG2 (42V, 2A).”
That would mean the panel outputs around 80W of solar power, which the company says can recharge its batteries in just three hours. That fairly quick recharging speed is helped by the fact that JackRabbit’s batteries are a mere 151 Wh, or around a third of the size of most e-bike batteries.
If that sounds small, then you’re right – it is. But JackRabbit is all about going micro, offering barely 25 lb rideables that are easy to store and bring on adventures, even when they aren’t actually being ridden.
With small batteries that fit under the 160Wh limit for many airlines in the US, the batteries can be quickly charged and taken to the widest number of locations. And for riders that want to go further than a single 10-mile (16-km) battery will allow, extra batteries are small enough to fit a pants pocket. The company also offers much larger Rangebuster batteries, though they won’t pass by TSA and make it onto an airplane in your personal item.
It sounds like the Solar Chargking Kit should be able to charge up JackRabbit’s large RangeBuster batteries, though likely in more than three hours.
The $349 Solar Charging Kit is a bit pricier than building something similar yourself, but it’s also safer and more convenient than hacking together your own battery charger since it’s designed to work with JackRabbit’s batteries right out of the box.
Technically it’s only inteded for JackRabbit’s micro e-bikes (themselves technically seated scooters, even if they look and feel more like a typical bike), but it’d probably work for just about any 36V e-bike that requires 42.0V to charge.
This isn’t the first time we’ve seen solar charging kits for electric bikes, and it’s a trend that is certainly appreciated by outdoors and camping enthusiasts, festival goers, or anyone who finds themself and their bike spending extended periods in the great, sunny outdoors.
