Charging or changing electricity? Or is it a combination of charging and replacing? Electric vehicles may usher in new opportunities in solving mileage fears and energy supply methods.
Fear of mileage and difficulty in charging have always been considered as two major factors that hinder the popularization of electric vehicles. In recent years, with the continuous improvement of the cruising range of mainstream electric vehicles, a number of listed models have a cruising range of more than 500 kilometers this year, and several 600-kilometer models are ready to go, and the mileage fear is gradually fading.
Compared with the cruising range, the charging difficulty has not changed much.
From the spectator's point of view, this model has the following challenges.
First, to change the chassis structure, it is necessary to intervene from the design and development stage of the vehicle model, and even a large part of the design work of R&D is handed over to Bertin. It is doubtful whether the OEM can accept it.
Second, the entire three-electric system of the model is provided by Bertan, and the car factory has no control at all. In addition, the car sold by the car factory only has a body without batteries, and the later operation is not in their hands, which will definitely make the car factory very cautious.
The above two points determine that it is difficult for large-scale, technologically strong and relatively strong automakers to adopt this model. If we want to promote this model on a large scale, we need to wait for the competition in the electric vehicle market to become more intense, or readjust the proportion of the right to speak with OEM partners.
A new advantage is that the subsidy for electric vehicles is decreasing year by year, and it will be completely cancelled in more than a year. Battery costs will be borne by consumers. Once the user's expectation of cruising range is raised, it is difficult to fall back. Battery replacement mode will be a good solution.
It is an exaggeration to say that the charging mode is completely replaced by the vehicle-electric separation and battery splitting mode, but in the future, the coexistence of multiple modes must be a relatively long-term situation, and eventually the market will choose one or more of the most suitable combinations.
When charging the battery, charging cabinet will collect the serial number, voltage, electric quantity, temperature and other data of the battery and upload them to the cloud system developed by Botan Technology. The algorithm system will adjust the battery charging mode according to the different state of each battery, and optimize the charging and discharging of a single battery in the battery pack, thus solving the problem that the performance of a single battery in the battery pack is insufficient at present, and achieving the purpose of prolonging the battery life. The actual operation data show that the battery life can be improved by 30-40% by the single-pack charging optimization strategy.
The power exchange station adopts mileage charging method to charge the power exchange service fee to the power exchange vehicles. According to the different owners and operators of power exchange station assets, the service charge rate is slightly different. Typically, the rate standard is 0.4 yuan/km. This rate has completely covered the construction cost of the power station, the depreciation of the circulating battery, and also considered the cost of replacing the battery after the battery life of the vehicle is exhausted in the future, which can realize the worry-free electricity use of the owner.
