Thoughts on new energy vehicle power batteries and charging stations

Thread Content

I’m not sure which section would be more appropriate for this post, so I’m posting it here as I have done in the past. If there’s anything inappropriate, please ask the moderator to make the necessary adjustments. I don’t want to comment on whether in-vehicle power batteries are considered new energy sources or clean energy sources. Today, I just want to share my thoughts on charging stations and vehicle battery power, as a way to stimulate further discussion. I don’t understand how a charging system that is both time-consuming and costly, and moreover extremely inefficient to use, could be deemed part of **strategic planning**! The main disadvantages of the vehicle battery charging station approach are as follows: 1. No matter how many charging stations there are, it is not possible to achieve the same efficient energy replenishment as at gas stations, where one can refuel quickly upon arrival ； 2. On the other hand, an excessively long charging time inevitably results in a low effective utilization rate of the charging station per unit of time ； 3. Charging stations not only consume a large amount of the city’s valuable parking space but also result in significant waste of public parking slots ； 4. Charging stations, as well as the associated power distribution and transformation equipment and circuits, pose significant safety risks, especially in older urban areas or in cases where the power distribution and transformation switchgear and circuits were not designed or modified specifically for use with charging devices! (In fact, the frequent charging accidents involving electric two-wheeled vehicles these days prove that there is a serious safety crisis related to charging.) 5. An excessive number of scattered charging stations is not conducive to managing the load on the power grid....................... My approach is to control the number of public charging stations in a moderate manner and to plan the distribution of charging stations in cities in a scientific way. Then, the focus is placed on the construction of centralized charging facilities for electric vehicle batteries, as well as the development of a decentralized model for replacing these batteries at various locations. 1. Electric vehicle batteries are classified into different energy levels, similar to dry batteries numbered 1#–7#, and **standards are used to standardize the physical dimensions and wiring interface configurations of batteries in each level** ； 2. Make the power battery an optional feature when purchasing a vehicle, removing it from the standard equipment and leaving its production to private manufacturers, with consumers purchasing it on their own. Only in this way can there be full competition among social resources, technologies, and capital, thereby rapidly reducing the technological complexity and usage costs of on-board batteries for electric vehicles. This would alleviate users’ concerns regarding long-term usage, as well as the hassle and waiting time associated with charging ； 3. Taking into account the layout of power generation and transformation facilities in various areas, charging stations should be built on a centralized basis. Meanwhile, battery replacement points should be established in streets and communities; it is even possible to adopt the current online food delivery model to offer battery replacement services at customers’ homes. The cost of batteries operates in a manner similar to the buying and selling of bottled water; it is covered by a battery deposit plus the charging fee for battery replacement. With this model of centralized charging at charging stations, it is possible to carry out charging during the off-peak times of the power grid. This allows power plants to abandon their previous practice of reducing load at night, thereby maximizing their efficiency and productivity. At the same time, maintaining high combustion efficiency over extended periods helps to reduce pollution emissions. Of course, this is possible only on the premise that **battery energy standards and battery dimensions must be standardized; only then can a revolution be brought about in electric vehicles, and can they truly be promoted on a wide scale. The benefits of charging factories go far beyond these points; upon closer consideration, the changes are truly terrifying! ! What they will bring is a revolution in the industry! 4. The optimal time for centralized charging at charging stations is during the off-peak electricity generation period at night, from 23:30 to 07:00; this is something that everyone understands ； 5. Of course, following this approach, there are many subsequent management requirements and regulations that need to be addressed. For example, establishing technical standards for batteries (energy density, physical dimensions, interface standards, charging and discharging technical parameters, battery charge/discharge current density, battery lifespan – it’s best to calculate this based on the number of charge cycles), as well as evaluating the quality of charging at charging stations, etc. All teachers are welcome to share their opinions and criticisms; fellow netizens are also invited to offer their feedback and guidance!
