Lithium-ion batteries for Van Pack Jetter
World’s first fully electric sewer cleaning machine
The reduction of exhaust gases is a common goal nowadays. For this reason local authorities, manufacturers and suppliers try to reduce their carbon footprint. As a result the use of generator driven equipment and machinery becomes more and more restricted. This shared ambition leads to a growing market of electrification. For instance the company Rioned answers to this growing demand. Recently they introduced the eCityJet: world’s first fully electric Van Pack Jetter. Powered by MG lithium-ion batteries.
Zero emission and maintenance free
To sum up the advantages of this electric sewer cleaning machine. Zero emission and clean operation are the first and most important one. The electric driven Van Pack Jetter doesn’t produce any harmful exhaust gases. Moreover, the system is silent during operation. This makes it ideally for use in urban areas, where strong regulations are applicable. An additional advantage of this generator replacement solution is that a lithium-ion battery pack is maintenance-free.
The lithium-ion battery installation
Looking more in-depth to mobile installations, there are many cases of conflicting requirements. For example, how to make sure to have the highest available capacity installed? After all, a high capacity of a battery bank will result in longer operation times. On the same hand, the battery installation has to be as compact and lightweight as possible.
Batteries with the highest energy density
These requirements – capacity, low weight and limited space – leads to the search of a battery with the highest specific energy density. MG’s HE200 lithium-ion battery has a specific energy density of 175 Wh /kg. One of the highest available densities in the market. Therefore, the HE200 battery is the ultimate choice to answer the customer needs.
To provide enough energy, in total 6 pieces of the HE200 lithium-ion batteries have been installed on a rack-system. Thanks to the high energy density, the total weight of the battery bank is only 172 kg.
This all-electric sewer cleaning machine has all the features of a conventional diesel-driven van-pack and is only marginally heavier. The empty jetting machine weighs approximately 600 kg.
