Good morning, good afternoon and good evening wherever you are in the world, welcome to EV News Daily for Sunday 12th April 2020. It’s Martyn Lee here and I go through every EV story so you don't have to.
BMW 7 SERIES ELECTRIC RUMORED TO HAVE AT LEAST 650 HORSEPOWER
"When BMW announced the beefiest version of the next-generation 7er will have zero emissions, it didn’t disclose any details about the power delivered by its electric motors. Now, our pals at BMWBLOG claim to be in the know about the hottest version of the fullsize luxury sedan." says Motor1: "Rumored to be called Mi7 or i7 M60, the range-topping 7 Series is said to have at least two electric motors delivering a combined output of 650+ horsepower or about 50 hp more than the M760i. The report goes on to mention the flagship 7 Series will have a large battery pack with a capacity of over 100 kWh for a range between charges of up to 400 miles (644 kilometers). It won’t be the only M Performance version as below it will reportedly sit a plug-in hybrid model tentatively called M750e with a turbocharged straight-six 3.0-liter combined with an electric motor. The electric derivatives will have some stiff competition coming from existing models such as the Porsche Taycan and Tesla Model S as well as from the upcoming Audi E-Tron GT, Jaguar XJ, and the Mercedes EQS."

InsideEVs has more info on the pack sizes: “Regarding the i7, there will apparently be (at least) two variants. One will draw juice from an 80 kWh battery pack while another will have an even bigger 120 kWh pack; this should take it up to 600 km (385 miles) on a single charge, and there’s a good change it will only be offered in the long-wheelbase model in order to actually have enough room for the pack to fit.”

HOT PLUG-IN HYBRID VOLKSWAGEN T-ROC GTE
"The Volkswagen T-Roc range could potentially be bolstered by a high-performance GTE version in future, should the market produce sufficient demand" says Auto Express: "When asked during a press conference call if a performance plug-in hybrid for the T-Roc would be a good fit, VW’s Project Manager for Electrified Drivetrains, Dr Kai Philipp, said: “Our MQB technology gives us the possibility to do so.”Power would come from the petrol-electric powertrain that’s widely used across the Volkswagen Group. A 1.4-litre turbocharged engine is paired with an electric motor, which is capable of producing as much as 242bhp in the new 2020 Golf.However, the GTE would be more efficient than either: the 13kWh battery should enable an electric-only range of around 40 mile."

CONSTRUCTION OF TESLA GIGAFACTORY 4 REPORTEDLY POSTPONED
"After the super quick pace of work at the Tesla Gigafactory 4 (aka Giga Berlin) site in Grünheide, near Berlin in Germany, the activity now is almost frozen. Some were saying that Tesla is waiting for a permit, but the latest reports indicate that the company is revising its construction plan." says InsideEVs: "Tesla previously completed clearing the tree farm and ground leveling. The next stage would be the foundation, which seems to be postponed. Torque News reports: "We just got breaking news from Tesla Giga Berlin. Brandenburg’s public radio RBB 24 reports that Tesla has to postpone the construction of the foundation for its Gigafactory 4 in Grunheide, outside of Berlin." According to the State Environment Agency, Tesla wants to revise the approval documents on one more point: In response to criticism from local residents, the company had announced that the factory should use less water than originally planned."

LORDSTOWN MOTORS SHOWS ENDURANCE ELECTRIC PICKUP'S IN-WHEEL MOTORS IN ACTION
"Several automakers, from Ford to Tesla, are planning to launch electric pickup trucks, but startup company Lordstown Motors will have something that sets its Endurance pickup apart from the rest—in-wheel electric motors. A new video shows one of the in-wheel motors in action." says Motor Authority: "Mounting the motors inside the wheel hub frees up space, and offers the potential to more precisely control how much torque is sent to a wheel. Torque can be added or subtracted by adjusting the amount of current going to the motor, rather than using the clutch packs, differentials, or brake applications typically used to adjust torque split. Lordstown says the Endurance carries a base price of $52,500. It is accepting $1,000 refundable deposits for early build slots. In comparison, Tesla says its Cybertruck starts at $39,900. Lordstown has said it will start deliveries in the fourth quarter of 2020. Lordstown is also targeting commercial fleets, while the Cybertruck is aimed at individual retail buyers."

ELECTRIC CAR WAITING TIMES REVEALED
"The average waiting time on a new electric car has significantly dropped in the past 12 months, with the majority of new electric vehicles now available within 12 weeks, according to What Car?’s analysis of all 26 electric models currently on sale." says WhatCar: "Last year, lead times for some electric cars exceeded more than 12 months, making it nigh-on impossible for buyers to commit to purchasing one. the Kia e-Niro, had a waiting list that extended to more than a year 12 months ago. As a result of increased supply, its lead time has been halved to 26 weeks. The longest wait is on Porsche’s first electric car, the Taycan (36 weeks), followed by the Seat Mii electric and Skoda Citigo e IV (26 weeks). Even cars with the shortest lead times, including the all-new Peugeot e-208 and new Renault Zoe, are available with discounts"
Zoe 1-12 weeks
Audi e-tron: 12 weeks
BMW i3 - 20 Weeks
IONIQ - 18 weeks

QUESTION OF THE WEEK
Paul Carnall
As I'm still working it's charged up 100% . But as I've got a long weekend off I'm leaving it at 80% . But in the past I've had the leaf plugged in at 100% for 3/4 days. Holidays when I've flown from the airport 30 miles away left it for two weeks at 60/70% . TBH I don't think it matters short term. Eg long weekend. But longer term week to two weeks plus I would say leave around 80% . Just my experience of 3yrs EV driving

Hi Martyn,
Regarding your question of the week. I keep my Nissan Leaf connected up to my V2G charger. I have set it to charge to maximum of 95% and discharge to minimum of 25%. It tends to do one full cycle over a 24 hour period. I have been on the OVO V2G trial in the UK since July 2019 and have seen no significant battery degradation in that time. The current lockdown just means the car spends more time connected to the V2G charger and goes some small way to help smooth out the demand peaks. The best part is that I have had basically free electricity for my home and EV since the trial began :-)

Car models may have special needs in layup. Chevy/Holden Volt Amperra will only maintain the 12 Volt battery if it is "rumning" or plugged in. Cant choose SOC so mine sits plugged in at 100% SOC = 85 % REAL. Also need to run it for 10 minutes on gas every month or so.

We're keeping our 2013 Nissan LEAF at 80%. We're not sure if we should keep it plugged in all the time or not. We are still driving it 1 or 2 days a week for small trips, so we could charge just one night every week if that's better for the battery's health

I parked up my Ioniq with about 75% charge as that’s what it was at when I last parked it. Once every couple of weeks I will go to the (remotely located garage) and change it’s parked position and leave the car on for 15 minutes to recharge the 12v battery. Tbh the 12v battery worries me more than the HV battery.

If the car is parked for a long time leave it at 50-60% no more.

Our Audi E Tron is setting @ 79 miles in the garage, here in FL USA. Probably not going anywhere for a while. Getting groceries delivered.

The BMW i3 manual is pretty clear. If you are leaving the car for over 3months then it should be plugged in. It has so little vampire drain that as long as it’s on reasonably high charge frankly there’s nothing really to worry about. There is no facility to set a charging limit, e.g. 80%, like a Tesla or Kona so you’d have to unplug manually at the right time if you wanted to leave it short of 100%. One important thing is, the i3 battery management has ‘passive cell balancing’ which is best done at 100% [it does happen at high charge but what level is unclear] so having the car idle is an opportunity to leave it balancing and getting a deep sleep.
[The manual is equally clear about not leaving the car on low charge. What is low? Well, it won’t let you turn on the heaters while sitting waiting at a rapid charger if it’s under 12%, so clearly the BMS is unhappy there. I drove back from Poole in 2017 with only 6 or 7% left and didn’t charge it back up for over a day – I’m sure the car emailed me it was unhappy, but I can’t remember for sure…!!]. I think most EVs need to be concerned about is their 12Volt batteries and it’s worth waking up the car, switching it on for say 20mins letting the DC to DC converter do it’s work [especially if they are a few years old]. I expect the i3 manual on the 3month lay up is thinking about this issue.

I’m a physician so I’m driving 80 miles a day or more! In the past however when I have left the EV for a week or so, I left the battery at about 50% under the assumption that the battery dislikes extreme states of charge or discharge.
QUESTION OF THE WEEK
How can the EV industry help people get driving electric as soon as this is all over?
