Geely Technology Group, part of the Geely holding, has presented its own technology for fast replacement of traction batteries in electric vehicles – E-Energee. It has been prepared since 2017, for the implementation of the project, the staff of the research and development department was increased to more than a thousand people, and in the process several hundred patents were registered, including for architecture for future electric cars, initially adapted for quick-detachable battery packs.
Strictly speaking, the first station using E-Energee technology opened in the metropolis of Chongqing in southwestern China back in September 2021, and by now it is already a network covering 10 provinces, but now Geely’s technology division has announced a bold plan: to cover the entire country with such points by 2025, bringing their total number to five thousand.
The company noted that the service is already popular with operators of commercial fleets, since the abandonment of traditional charging at the terminal allows to reduce downtime. It is stated that the entire procedure takes a symbolic 59 seconds, while you do not need to get out of the car, registration and payment are made automatically.
There is nothing fundamentally new in the quick replacement of batteries in electric vehicles: in the same China, a similar service is provided, for example, by the Nio brand. Tesla back in 2013, as an experiment, suggested changing a discharged battery pack using a robot in a minute and a half for a new one, but later the head of the company, Elon Musk, said that this did not cause much enthusiasm among car owners: most continued to use branded “Superchargers.” >
In Europe, Renault is the pioneer of such a service: the company sold electric cars at a reduced price, and rented batteries to buyers. Later, the same Zoe hatchback – one of the most popular models of its segment in the EU – was allowed to be purchased as a whole, along with the battery, but the idea itself has not lost its relevance. For example, the head of the French group, Luca de Meo, recently told reporters that this technology will simplify the replacement of a used power source, which can then be reused, for example, in modular “battery farms” for energy storage.
