The development of electric vehicles can be described as in full swing, although at present for major brands, traditional fuel vehicles are still the most critical source of profit, and electric energy-related technology is the focus of showing "research and development muscles", but in addition to the continuous introduction of a richer electric army, the use of related software and hardware is also a stage that major brands cannot be absent. Porsche recently used the Taycan series to demonstrate the practical value that the Taycan can provide in the V2G (Vehicle-to-grid) function.
Electric vehicles are equipped with tens of degrees (kWh) of battery capacity, which also means that electric vehicles can be directly imagined as a huge mobile power supply, V2L (Vehicle to Load), that is, the practical value of electric vehicle power supply is generated, in terms of electric vehicle battery capacity, corresponding to home appliances or any electrical products, should be more than comfortable; and in addition to power supply to electronic products, many brands are also actively exploring V2G, that is, Vehicle to The complementarity between Grip electric vehicles and the grid.
Whether it is V2L or V2G, its practical intention is to want to complete the good power, especially in the V2G part of the vehicle to the power grid, the starting point is that most people need to use the vehicle, in fact, it is only needed in traffic, the remaining most of the time the vehicle is parked on the parking grid, if the electric vehicle is parked, if it can be more efficient to use "electricity"; through the electric vehicle's electrical energy feedback to the grid, to assist in the abundance and stability of electrical energy, of course, this also needs to cooperate with the smart grid, including charging when off-peak ( Electricity is cheaper), power supply during peak hours (to make money or get discounts, etc.).
Such the use of electrical energy for hardware has a certain demand, simply from the charging pile charging to the electric vehicle, which is a one-way flow of electrical energy, and in the V2G part of the two-way electrical energy application, as mentioned earlier, the electric vehicle can also be through the charging pile and the energy management system, to lend the electric energy on the car to the grid, at this time the electric vehicle is like a "battery".
However, V2G is not a large-scale application, but is more suitable for the use of small areas, if the power supply source of the power company is like a reservoir metaphor, through the diversion, pressure reduction and other layers of processes, wait until the 110V, 220V used in everyone's home, in fact, it is already the level of water pipe size; on the other hand, if you want to make up the reservoir through the size of the water pipe, even if tens of thousands of water pipes are not easy, but if it is for a small area, it will have a more obvious help.
Porsche recently through the media official website to show the V2G efficacy, in fact, the more important value, but in the V2G function of the Taycan, become an excellent buffer (Buffer) to assist in the stability of the regional grid, Porsche through 5 Taycans under the management of HEM and the grid connection, in the charging also to help test the stability of the range of the grid. Porsche also said that the use of V2G, HEM and other systems revealed that the benefits of electric vehicles are not only traffic vehicles, but also have more development possibilities.
