July 6th news, according to the electrek website, Tesla CEO Elon Musk said that Tesla may 're-examine' the technology of the car connected to the grid.
The Tesla first-generation roadster has the ability to output power from the car battery pack to equipment other than the engine. This technology is often referred to as 'car to grid' or 'car to home' and can be used by electric vehicle owners. The battery pack of its electric car is for home power supply.
Since then, Tesla has abandoned the technology in its introduction to the mass market, but other automakers have set their sights on it. Now, Musk said Tesla is also considering reusing the technology. .
The outside world had expected that the emergence of electric vehicles would increase the demand for electricity, but electric vehicles also provided some advantages by controlling the power load.
A recent study shows that by controlling electrical loads and using 'automobile to grid' technology, electric vehicles can save billions of dollars in electricity costs while enabling the grid to make better use of renewable energy.
Control the load, that is, the control ability of the electric vehicle when charging. As long as it is connected to the intelligent charging station, any electric vehicle can realize the control of the electric load.
This alone, by reducing the peak electricity consumption, can only have a huge impact on the grid when charging during the electricity valley period. Research shows that the 'automobile to grid' technology - electric vehicles will be powered by two-way chargers Returning to the grid will have a more beneficial effect.
For many years, Nissan has been testing the 'Voice to Grid' (V2G) system using the Leaf model. With the launch of the new generation of Leaf, Nissan has also demonstrated a new electric vehicle ecosystem, including plans to provide free electricity to owners of V2G systems. Nissan's new generation of leaf models can support V2G systems.
Tesla is gradually becoming the world's largest manufacturer of electric vehicles, and it already has the largest lineup of electric vehicles in terms of overall battery capacity.
The company has a huge impact on both controllable loads and V2G, but for the latter, Tesla seems to have doubts, because in terms of household energy storage, Tesla is more focused on its fixed battery system.
In the tweet released last night, Tesla CEO Elon Musk said he would like to re-examine the technology used in Tesla cars: 'A long time ago, we had the ability to make the car act as a battery. Energy output. May be worth revisiting. ' -ElonMusk (@elonmusk) July 4, 2018
This is not the first time Tesla has talked about reusing V2G systems in its cars. We have previously reported that Tesla has been thinking about using a two-way home charging station to realize the idea of 'car to grid' for a while. However, during the opening of the 2016 Tesla Shareholders' Meeting and the Gigafactory factory, Mask and Tesla CTO JBStraubel poured a cold water on the idea, saying it was not a priority.
Later, at the InterSolarMiddleEast conference in Dubai, Tesla was the EMEA region (ie, Europe, the MiddleEastandAfrica, acronym for Europe, the Middle East, and Africa). Energy director BenHill hinted at Tesla in his speech. There are some car-to-grid pilot projects. He said: 'There are many pilot projects around the world that connect battery systems to the grid, regardless of whether the battery pack is not in the car. Such technology will soon appear. Today, the plan has not been realized, but it seems that Musk is currently rethinking this technology.
Analysts pointed out that in addition to V2G technology, Tesla seems to be more interested in controllable loads and the value of the technology as the number of customers grows.
The outside world can understand why Tesla did not take this as a top priority. 'Car to grid' is a very attractive additional feature of electric vehicles, but there are some drawbacks. For example, if customers are looking for permanent home energy Storage solution, that V2G is obviously not. You can't expect your electric car to have enough energy to be used as a household energy storage. There is also the problem of battery aging, if you keep the battery between household and driving constantly switching. , will accelerate the aging of the battery. Therefore, if you want to have backup power at home, it is best to use a real home battery system.
However, in an emergency, the V2G backup power supply is still a good feature. The versatile Tesla battery pack can supply the average household for several days, which is usually much more than the power provided by the home battery pack.
