With the increase of the number of electric vehicles, it is a new problem for many countries, regions and enterprises to treat or recycle the batteries that have been eliminated. However, an overseas enterprise, through recycling, also gives a good solution. Sweden’s eco sightseing company recycles the old batteries of Tesla Model s and uses them in the Sylvia passenger ship, making it an electric passenger ship with more environmental protection and energy saving properties. < / P > < p > this passenger ship, called Sylvia, belongs to eco sightseing company in Sweden. It mainly provides tourists with boat tours. It uses old batteries recovered from Tesla Model s as power source, which is the first product to use Tesla batteries for the second time. < / P > < p > the ship is equipped with a 190kwh battery pack which can power an 85KW electric motor, and the cruise time of a single charge is about 14 hours. < / P > < p > the Swedish company said the batteries were contained in a specially designed waterproof airtight aluminum container under the captain’s chair. Ecosightseing doesn’t say when Sylvia will start carrying passengers, but it can carry about 49 passengers. < / P > < p > however, it is a more cost-effective way to continue to use these eliminated batteries in other work scenarios that do not require high battery performance. This also provides a reference operation method for the treatment and recycling of waste vehicle batteries in the future. Didi Qingju bicycle has entered 150 cities
