However, electric bicycle The weakness is that the battery capacity is low, so the vehicle’s range is limited and to solve this problem, Tongneng New Energy company has invented a new battery that provides a range of up to 600km/day. charger.
Electric bicycles are an ideal vehicle for users who only travel short distances such as going to the market, taking children to school or going to work. With the advantages of convenience, compactness, speed and affordable price, it is very normal for a family to own many electric bicycles.
Possessing a compact design and easy to use, electric bicycles are a vehicle that many families choose to use every day. |
But electric bicycles have a weakness: the battery does not last long, it can only run a short distance before needing to be recharged. In other words, electric cars are very convenient but the “heart” of electric cars, the “battery”, is not strong. Weak batteries and having to charge them frequently is the obsession of many people electric bicycle users.
So the question is whether there is a battery with large capacity, long usage time, allowing electric bicycles to travel hundreds of kilometers on just one charge or without needing to be charged regularly for a long time? This is certainly a question that many electric bicycle users have asked.
Accordingly, a Chinese new energy company called Tongneng New Energy – specializing in developing and manufacturing lithium-sulfur batteries, has achieved unimaginable results through internal testing. Specifically, this company has used lithium-sulfur batteries to replace conventional electric vehicle batteries and the theoretical travel range can increase 13 times.
Use lithium-sulfur batteries to replace conventional electric vehicle batteries and the theoretical range can be increased 13 times. |
Tongneng New Energy company technicians bought a regular electric bicycle on the market, fully charged it and traveled 48 km before the battery ran out. It should be noted that this electric vehicle uses a common type of battery for electric vehicles with 4 battery packs and weighs about 11.8 kg.
During the test, Tongneng New Energy technicians did not fully install 4 lithium-sulfur batteries of equivalent mass. Instead, they only equip a battery pack of the same size and weighs only 1.9 kg.
Reduced by 3 batteries and 10 kg lighter in weight, so how far can a lithium-sulfur battery pack go when used on the same electric bicycle? Test results show that the average travel distance after 3 tests is up to 99km, only 1km less than the 100km mark.
New generation lithium battery with energy density of 700wh/kg, 3 to 5 times higher than popular lithium-ion batteries currently on the market. |
Operating range of nearly 100 km with 1 battery pack and 10 kg lighter, this result is surprising. However, Tongneng New Energy’s technical staff believe that this is not the most ideal result.
According to the report, Tongneng New Energy’s latest successfully developed lithium-sulfur battery is a new generation lithium battery with an energy density of 700wh/kg, 3 to 5 times higher than today’s popular lithium-ion batteries. on the market.
According to practical applications, under normal conditions, an electric vehicle equipped with a lithium battery has a travel range of about 400-600 km. But under the same conditions, if you replace this new lithium-sulfur battery, the travel range can reach more than 1,200 km.
According to practical applications, under normal conditions, an electric vehicle equipped with a lithium battery has a travel range of about 400-600 km. |
So if you replace the lithium-sulfur battery, how far can an electric bicycle go? Tongneng New Energy technicians said that the energy density of lithium-sulfur batteries is measured in wh/kg.
To make it easier to imagine, the electric bicycle mentioned before, if a lithium-sulfur battery with the same weight of 11.8kg is installed, the theoretical travel range can reach more than 610km, compared to only 48km when using the battery normally. If an electric bicycle can travel more than 600 km on a single charge, that must be an extremely wonderful thing for electric bicycle owners.
Ongneng New Energy said: “We are confident that we will complete the test and achieve positive results.” |
Of course, Electric bicycles can run more than 600km is still just a theoretical number, calculated based on internal test data. To determine accurate data, Tongneng New Energy will organize a test of electric bicycles using lithium-sulfur batteries with the goal of conquering a distance of 600km.
