When your Tesla is idle — that is, not driving or charging — you may experience what's known as  phantom drain, where the battery slowly drains a few percentage points over the course of several hours. Phantom drain happens when the vehicle stays awake and doesn't sleep to conserve battery.

The list below includes all known causes of phantom drain on Tesla vehicles and how to fix it:

1. Disable Sentry Mode
   Sentry Mode will keep the vehicle awake to monitor the surroundings.
   
   
2. Disable Cabin Overheat Protection
   Cabin Overheat Protection will keep the vehicle awake to monitor and cool the interior.
   
   
3. Disable Data Sharing
   When data sharing is enabled, the vehicle will wake and upload data to Tesla in the background.
   You can disable it in the vehicle under Software > Data Sharing.
   
   
4. Don't use multiple Tesla tracking apps
   When one service is letting your vehicle sleep, the other may be keeping it awake inadvertently. This is a side effect of how the Tesla firmware is currently designed.
   You can reset access to all tracking apps by changing your tesla.com account password.
   
   
5. Install pending software updates
   The vehicle may stay wake when an update is pending but hasn't been fully downloaded and installed.
   
   
6. Move devices outside of Bluetooth range
   When a Bluetooth connection occurs, the vehicle may wake up automatically.
   
   
7. Update the Tesla app on your devices
   Certain Tesla app versions have a bug which will continuously wake the vehicle.
   
   
8. Move key fobs away from the vehicle
   When a key fob is detected near the vehicle (including vertically, in a room above or below the vehicle), the vehicle may wake up automatically.
   
   
9. Improve the WiFi signal
   Weak WiFi connections can cause the vehicle to stay awake due to constant disconnections and reconnections. You can turn off WiFi in the vehicle or move your WiFi router to improve the signal.
   
   
10. Disable Summon Standby
    Summon Standby will keep the vehicle awake. You can disable it in the vehicle under Autopilot.
    
    
11. Remove the Tesla app widgets from your home screen
    The Tesla app widgets communicate with the vehicle and may keep it awake. You can use Tessie widgets safely.
    
    
12. Restart the vehicle
    There is a known computer issue that can prevent the vehicle from sleeping. You can restart the vehicle by pressing both scroll wheel buttons on the steering wheel until the screen turns off.
    
    
13. Power cycle the vehicle
    Underlying firmware issues can also prevent the vehicle from sleeping. You can perform a power cycle to eliminate them.
    
    
14. Reduce polling interval
    In certain conditions, the Tesla data API may wake the car. In Tessie, change Settings > Connectivity > Polling Interval to 60 seconds and wait 24 hours to see if it helps.
    
    
15. Replace the 12V battery
    Many Tesla owners have had success in reducing excessive wakes by getting the 12V battery serviced or replaced.
    
    
16. Service the vehicle to fix the underlying components
    Your Tesla will automatically wake up when an underlying component activates.
    Some components, like the HVAC system and certain sensors, can be faulty and activate needlessly, which will cause the vehicle to wake up.
    Replacing these components will allow the vehicle to sleep normally.

• Battery Pack - 40kWh Lithium Ion, occupying ~0.25 cubic meters of space.
• Battery Weight - 450kg (1000lbs)

1. It takes only a few tenths of a second for the ZOE e-sport concept's motors to reach 4,300rpm.
2. Its doors are opened by a simple tap on the 'open' zone incorporating tactile sensors.
3. The dash panel features three zones that permit management of the gearbox, driving mode (four options available) and brake distribution.
4. An air-and-water cooling system with a front-mounted radiator is used to make sure that the battery and control systems operate at the ideal temperature.
5. The electronic settings offer four driving modes that adapt, depending on whether the driver wants performance or a longer range. They can also be tailored to suit different types of circuit and driving styles, adjusting the power delivery between the two motors to place greater emphasis on front or rear-wheel drive.

1. Formula E, officially the FIA Formula E Championship, represents the world's first fully-electric racing series. Foreshadowing the motor industry’s development in the coming decades, it provides a framework for R&D while accelerating interest in electric vehicles and promoting sustainability. 
2. The series was conceived in 2012, and the inaugural championship started in Beijing on 13 September 2014. The series is sanctioned by the FIA. Alejandro Agag is the current CEO of  Formula E.
3. Operating as an 'open championship', the series gives manufacturers the opportunity to showcase their energy technology in a competitive environment by designing cars to technical specifications set out by the FIA. Formula E fully complies with the same FIA standards as used in Formula 1
4. It centers around three core values - energy, environment, and entertainment - and represents a fusion of engineering, technology, sport, science, design, music, and entertainment.

1. Growth in urban population, rising mobility of people and goods, and consumer trends are changing the environment. As global megatrends are creating difficulties for governments, businesses, and individuals to create integrated solutions, the demand for platforms where different actors can exchange ideas to sustainability challenges, is increasing.
2. Formula E acts as a catalyzer for technology innovation, it brings together major global corporations that recognize the benefits of developing cross-industry collaborations and of jointly building innovative and sustainable solutions. Formula E is a perfect place to test custom batteries, and there’s a good chance a breakthrough energy-storage device will debut here. 
3. Using cutting-edge technology, the Formula E aims to push the boundaries of what is currently achievable in electric motorsport. While striking a balance between cost-effectiveness and sustainability, it will also rise to the challenge of racing solely on street circuits. Formula E cars have a potential problem not found in Formula One.
4. Formula E drivers have their fuel when they start the race, but they can keep topping it up as they can regenerate, Drivers are looking at the total amount of fuel, that is, the "charge", how much of it is left and accordingly how hard do they have to push that energy, to use that fuel out of the corners or on the straights, and how much braking they should do, how much speed should they carry through the corners. They have to manage regeneration off of the braking, if they brake very harshly, that impedes the ability of the system to regenerate, as braking less sharply helps to conserve energy. A challenge for the teams is how to make the most of the available charge, but also how to add more to the charge.
5. In a lithium-ion battery, a very publicized problem is them getting too hot during their operation. It’s an exothermic reaction: so they just keep getting hotter, thereby becoming potentially unstable. Most battery cells need to be <65C, and for stability and performance, the battery temperature needs to be between 35C to 40C.
6. While a Formula E car is not as fast as a Formula One car, it is nevertheless a serious racing machine built by some of the world’s top racing experts.
7. The Founding Partners of Formula E decided that it would be a platform to boost sustainable innovations, a gateway to the cities of tomorrow and alternative transport. After the very first Formula E season in 2014-2015, this dream is already becoming a reality – and the best is yet to come.

Technologies Used -

1. Spot Cooling -
   The Immortus needs to use little energy, and air-conditioning is not an option. Therefore, the driver will be cooled with the strategic application of vented air. The knowhow that comes from this will be of value to other car makes looking to increase efficiency via better cooling approaches.
2. No Side Mirrors -
   The Immortus, to be aerodynamic, will not have side mirrors. Instead, cameras in the rear of the vehicle will be used with screens inside to allow the driver to perceive the events behind. The knowhow and system developed doing this prove a potential to be superior to current systems. 
3. Regenerative Shock Absorbers -
   Traditionally an academic pursuit these shock absorbers are so ideal for a solar car that they are being developed to take them from the theorised to the applied.
4. Air Cooling -
   The Immortus must be light and always needs to charge and discharge. This means effective battery management and the effective use of air cooling as opposed to liquid cooling, which is heavier and also more prone to failure due to the extra parts.

1. This car is inspired by the world portrayed in post-apocalyptic movies, the Immortus is designed to exhibit a toughness that no other car has: endurance. 
2. The ability to run on the power of the sun and store the energy for later use make it a car of practically infinite endurance. As long as the sun shines the Immortus lives...
3. The initial model will be a specialised vehicle to showcase this new technology, which will be presented as a high-end custom vehicle for high network individuals.
4. Looking at Tesla, EVX Ventures hope to replicate its strategy by first offering the Immortus as a luxury limited edition before affording it to the mainstream.
5. Electric vehicles still need to be plugged into a power source to charge and often that main power grid is a dirty, rather than clean and renewable energy source. With solar powered vehicles there are no external plug ins and the whole system, including power and refill costs, steps beyond that of previous electric vehicles.
6. The Immortus is currently our technology development platform where a 'concurrent engineering' approach is utilized. This approach has proven to be very economical and rapidly yields spin-off peripheral technologies with multi-industry applications.
   This project was a Finalist for Singularity University's Australian & New Zealand Global Impact Competition 2014. 
7.  EVX is an early stage venture focused in the R&D and commercialization of high performance solar and electric vehicle technologies. EVX's ultimate vision is to make self-powering cars the future of transportation.
8. EVX is supported by the research and development team at Swinburne University of Technology, one of the leading electric vehicle research groups in the world. Founded in Melbourne, Australia.

1. The Tesla Model V/5 is 12.5% smaller than Tesla Model E/3 and 30% smaller than Tesla Model S.
2. The car is specifically made for developing economies, thence, the ground clearance is kept relatively high and top speed is kept within appropriate legal limits.
3. Since the market for such a car would be predominately limited to metro-cities in developing economies, the range is not kept too high for long distance routes and is preferably useful for daily commotion within a city &/pr nearby places.
4. The low cost of the car allows it to be considered a more economic and more efficient alternative to compact diesel cars which also leads to lesser air pollution within cities.
5. To make the car's manufacture more geared towards developing economies, advanced hardware for technologies like "Autopilot", etc are left out which make this car simpler, cheaper, lighter and easier to manufacture.
6. The Tesla app in the user's phone is used, and the phone is docked in the dashboard as a substitute for the expensive Interactive digital display. This is done, as phones are predominantly used in developing economies and serve as a more portable and easy-to-use digital device for the less articulate masses. This reduces the final cost of the car.
7. The battery pack forms the bottom of the vehicle between the axles, concentrating the mass between the axles.
8. This distributes its mass equally on its axles and lowering its rotational inertia, allowing it to turn more quickly.
9. Since the battery pack is the single most heavy component of the vehicle, the car has a very low center of gravity height, due to the location of the battery pack.
10. This also helps in achieving a high lateral acceleration and an increased protection against rollover. 
11. The placement of the battery pack increases the rigidity of the passenger compartment, improving the passive safety of the car.

1. Electronic Vehicle Control Module (EVCM) (made by Zytek) provides the interface between the powertrain and the rest of the vehicle.
2. EVCM integrates powertrain control, by including torque arbitration, temperature control and voltage management to allow better decision making using algorithms.
3. Optimises the driver’s torque request based on a broad range of parameters including battery charge and temperature and the grip available at the tyres.
4. Provides more with less, improving both the driving experience and the range while reducing the size, weight and cost of the power electronics and battery pack 
5. Tested under the strict Euro-NCAP safety standards under Gordon Murray’s approval, with results that he claims are “first-class.”
6. Survived a EuroNCAP 50kph side impact mobile deformable barrier test with "virtually zero cabin intrusion"
7. World's Most Efficient Electric Car,
   Smart EV/ED uses 29% more energy/km,
   Mitsubishi iMiev uses 36% more energy/km,
   Mini-E uses 86% more energy/km.
