In the past two years, as various government departments have continuously increased financial subsidies for the promotion and application of new energy vehicles in public services such as sanitation, the new type of pure electric sanitation car has ushered in the development of “blowout†and at the same time The pure electric sanitation vehicle industry also ushered in a good opportunity for development. The classification of pure electric sanitation vehicles according to garbage collection and transfer vehicles, excrement vehicles and road surface cleaning vehicles can be classified into three categories.
Several of the more important parts of pure electric sanitation vehicles are analyzed; currently the chassis of all domestic electric sanitation vehicles are based on the chassis of traditional commercial vehicles, and the original work function is maintained without changing the traditional chassis frame. Under the premise of not being made, the power and structure are mobilized to develop and configure the drive system of a pure electric vehicle, including a drive motor, a rotation system, and a motor control system. Of course, the use of pure electric sanitation cars need to consider the type of car being modified. The nature of work, the quality of work that needs to be achieved, and the carrying requirements.
The battery of the chassis of the electric electric sanitation vehicle is made of lithium iron phosphate, and a small part of the chassis also uses lead-acid batteries, lithium manganese batteries and ternary lithium batteries. These types of batteries are lithium-ion batteries. Their price is very affordable, original materials are good, practical performance is also very reliable, and it is easy to meet the power requirements of electric vehicles.
The lithium iron phosphate battery used in electric vehicles is actually equivalent to the technical bottleneck of low-temperature performance and low specific power of ternary lithium-ion batteries, making it difficult to achieve breakthrough progress. With the advancement of technology, the security of the ternary lithium battery has been solved. More and more new energy vehicle companies in China are pure three-way lithium batteries that have larger capacity and better functionality than ever before. In order to meet the increase in the cruising range of pure electric sanitation vehicles and increase the demand for carrying capacity, in the next few years, the replacement of lithium iron phosphate batteries with lighter weight three-element lithium batteries will be the development trend for pure electric sanitation vehicle power batteries.
