Tesla is releasing a wide rollout of its Powerwall Coordination feature with Model Y vehicles in a new software update as California residents are experiencing power outages and rolling blackouts.

Software Update 2020.32.3 first appeared on a Tesla Model Y LR AWD on Saturday, August 22, 2020, according to TeslaScope, and included several rollouts for owners of the all-electric crossover who are operating with Hardware 2.5 or Hardware 3.0.

Among the new additions to the vehicle’s capabilities is a Powerwall Coordination feature, which aims to increase the efficiency at which a Model Y will charge when plugged into a home charger.

The release notes indicate:

“You car coordinates with Powerwall for enhanced charging during a power outage, without exceeding the energy and power capabilities of your Powerwall system. Powerwall continuously responds to the changing power needs of your home and will slow or stop your car’s charging, keeping your home loads powered.

During a power outage, your car will charge from the Powerwall whenever it is above the threshold set in the Tesla mobile app. You can change this threshold to balance your home and transportation energy needs, putting you in full control of your energy ecosystem. Powerwall can also use surplus solar to charge your vehicle during an outage if you keep your car plugged in while the sun is shining.

This release brings support to more Tesla vehicles, and was initially released for some vehicles in April 2020.”

Like the release notes state, the feature was initially rolled out to some vehicles in April. Tesla had worked on a system that would allow Powerwalls to communicate more efficiently with charging vehicles. This feature is especially relevant in present-day because many owners in California are experiencing issues with blackouts and power outages amidst an intense heatwave.

Last week, Tesla displayed a message on California owner’s dash screens that advised and encouraged them to charge during non-peak hours. The message asked owners not to charge their cars from 4 pm to 9 pm so that stress could be taken off of the grid, which would allow the state’s residents to air-condition their homes and keep their lights on adequately.

Tesla is making the feature more widely available for owners of the company’s vehicles now, as it appears to be increasingly useful given the current situation. If an owner is experiencing an outage, they will not have to sacrifice, giving their vehicle range from their home because of the lack of power.

This could also be effective if an owner is forced to evacuate their home due to wildfires.

China considering EV acceleration limits to curb high-speed accidents

If approved, the regulation would be a national standard.

Recent reports have emerged stating that China is considering new national standards that would restrict how fast electric vehicles can accelerate upon each startup. The potential regulation is reportedly being considered amidst a rise in EV-related crashes. 

The draft for the proposed regulation was released by the Ministry of Public Security on November 10. If approved, the regulation would be a national standard.

New regulation targets default performance limits

Under the proposal, all passenger vehicles would start in a state where acceleration from 0–100 km/h (0-60 mph) would take no less than five seconds. This rule would apply to both pure EVs and plug-in hybrids, and it is aimed at preventing unintended acceleration caused by driver inexperience or surprise torque delivery. 

The public has until January 10, 2026, to submit feedback before the rule is finalized, as noted in a CNEV Post report.

Authorities have stated that the change reflects growing safety concerns amidst the arrival of more powerful electric cars. The new regulation would make it mandatory for drivers to deliberately engage performance modes, ensuring they are aware and ready for their vehicles’ increased power output before accelerating.

A rise in accidents

China’s EV sector has seen an explosion of high-powered models, some capable of 0–100 km/h acceleration in under two seconds. These speeds were once reserved for supercars, but some electric cars such as the Xiaomi SU7 Ultra offer such performance at an affordable cost. 

However, authorities have observed that this performance has led to an uptick in accidents. I recent years, incidents of crashes involving lack of control in vehicles with rapid acceleration have risen, as per an explanatory note accompanying the draft. 

Part of this is due to drivers seemingly being unprepared for the power of their own vehicles. For context, driving schools in China typically use cars that accelerate to 100 km/h in more than 5 seconds. This level of acceleration is also typical in combustion-powered cars.

Tesla Superchargers crowned best EV charging network in the UK for 2025

The Tesla Supercharger network was voted Best Large EV Charging Network for the second consecutive year.

Tesla has once again claimed the top spot in the UK’s most anticipated EV charging satisfaction survey. As per Zapmap’s 2025 driver satisfaction rankings, the Tesla Supercharger network was voted Best Large EV Charging Network for the second consecutive year. 

The annual survey, based on thousands of EV driver responses, measures reliability, ease of use, and payment experience across the UK’s public charging landscape.

Tesla tops the survey’s “Large” category

Zapmap’s 2025 rankings, which were drawn from nearly 4,000 battery electric vehicle (BEV) drivers, reflect how quickly public charging is evolving across the UK. For the survey’s “Large” network class, which includes systems with over 500 devices, Tesla once again stood out for reliability and cost efficiency. 

The automaker now offers 1,115 open Supercharger devices at 97 public sites, roughly 54% of its total UK network. That’s a 40% increase in public availability compared to September 2024. A particularly appreciated aspect of the Supercharger network is its cost, which continues to be “significantly lower prices than most rapid/ultra-rapid networks, with drivers also appreciating its reliability,” Zapmap noted.

Tesla Regional Manager’s comments 

Ollie Dodd, Senior Regional Manager for Northern Europe Charging at Tesla, shared his appreciation for the Supercharger network’s award.

“We’re thrilled to win Zapmap’s Best EV Charging Network for the second year in a row. Being recognized by the drivers themselves shows that our customer-centric and data-driven approach to building sites is well-received. We look forward to showcasing more customer-centric features in 2026 as we expand the network further and look towards new initiatives in roaming and payment methods,” he said.

Conducted during September and October 2025, Zapmap’s eighth annual survey found that reliability and payment flexibility remain top priorities among EV drivers, two things that the Supercharger network particularly excels in. Fortunately for UK EV owners, the Supercharger network is also aggressively growing.

Volkswagen has announced that owners of the ID.4 and ID. Buzz will soon gain access to Tesla’s expansive Supercharger network across North America. 

Starting November 18, eligible drivers can charge at more than 25,000 compatible DC fast chargers using a Volkswagen-approved NACS adapter. The adapter, however, would need to be purchased by eligible customers. 

Volkswagen goes NACS

To connect with the Tesla Supercharger network, ID.4 and ID. Buzz owners will need a $200 Volkswagen NACS-to-CCS adapter, which is available from dealers or online at parts.vw.com. Original owners of 2025 models can claim a $100 rebate within 90 days of purchase, with the program running through July 15, 2026, as noted in a press release. Starting with model year 2026, the NACS adapter will be included as standard equipment on all new Volkswagen EVs.

It should be noted that Volkswagen’s NACS adapter enables charging exclusively on DC fast chargers compatible with Tesla’s North American Charging System. It cannot be used with Level 1 or Level 2 AC chargers, including Tesla’s own Destination Charger network. Select 2024 and 2025 models will also receive a software update to ensure optimal performance when charging through NACS.

Volkswagen of America SVP’s comments

Volkswagen of America Senior Vice President of Product Marketing and Strategy Petar Danilovic shared his excitement about the ID.4 and ID. Buzz’s upcoming use of the Tesla Supercharger Network.
