Definitely. To solve this problem, we must first understand how electric vehicles are charged. As we all know, charging cars are usually charged through charging piles or charging stations. This charging infrastructure is also called electric vehicle service equipment (EVSE). Charging methods can be divided into two types: AC charging and DC charging. AC charging connects the alternating current in the power grid to the on-board charger (OBC) inside the vehicle. The OBC converts the alternating current into high-voltage direct current through the built-in AC/DC and DC/DC circuits to charge the vehicle power battery pack. DC charging requires completing the AC/DC and DC/DC power conversion of the alternating current in the power grid in the charging pile, and then bypassing the OBC inside the vehicle to directly connect to the battery for charging, because these converters do not need to be installed in the vehicle. internal, so it can be designed for high power levels, allowing for faster charging.
With the development of the electric vehicle market, the construction of charging infrastructure will also accelerate. In the "new infrastructure" blueprint launched by China, charging piles are one of the seven core areas, and their importance and The strategic significance is evident from this. The development of charging piles, especially the development of DC charging piles with fast charging characteristics, not only requires profound technical accumulation, but also needs to keep up with the pace of rapid iterative upgrades of technical products, which is a big challenge. The rich product portfolio and overall DC charging pile solutions provided by TI will undoubtedly help accelerate this development process.
The low cost of electric vehicles is an advantage at this stage. In the future, improvements in convenience and timeliness will completely eliminate fuel vehicles. The key point is that once the "circuit" is built and popularized, the battery pack capacity requirements of electric vehicles will be very small and only need to meet daily short-distance transportation; then the price of the vehicle will naturally have a great advantage, which will accelerate the elimination of fuel vehicles One of the reasons is that the future will only belong to trams.
1. Electric vehicles will become the mainstream of future cars;
2. Lithium-powered battery vehicles will become the mainstream of electric vehicles in China;
3. Electric vehicles Cars will develop towards long endurance, intelligence, and interconnection.
The first stage of the development of new energy vehicles in China: the stage of replacing oil with electricity. For example, the BYD F3DM, JAC Tongyue pure electric vehicle, and Zotye 2008EV launched in 2010 are all based on traditional platforms.
As more and more new and old forces are involved, the competition has become increasingly fierce and has entered the second stage: in accordance with the research and development process of fuel vehicles and the speed of project advancement, calm down. It will take 3-4 years to develop its own pure electric vehicle platform. NIO’s ES8 and Xpeng P7 are products of this R&D approach. The advantage of starting pure forward research and development from the platform is that car companies can completely independently define product performance and styling. The entire vehicle architecture can be designed around the most critical performance of the vehicle's cruising range, and the vehicle styling can also be very original. These car companies have brought China's new energy vehicle industry into the originalIn the forward development stage, new energy electric vehicles have begun to evolve faster than fuel vehicles. The next development direction of the overall architecture of electric vehicles must be super chassis modules with a more compact structure. This kind of design is not only to reduce costs and improve efficiency, but more importantly, it can reshape the entire business model of vehicle R&D, sales and operation.
