The electric vehicle range extender is a device designed to solve the problem of electric vehicle range. The main function is to monitor the electric vehicle battery power in real time. When the battery power is lower than the set value, the range extender will automatically start. After starting, the chemical energy of the fuel is converted into electric energy through the built-in generator, and part of the generated electric energy is directly supplied to the drive motor of the electric vehicle, so that the vehicle can continue to run; The other part is used to charge the battery and replenish the power consumed by the battery. According to the driving state of the electric vehicle, battery power, load size and other factors, automatically adjust the output power and speed of the generator, in order to achieve the best energy distribution and utilization efficiency, to ensure the vehicle's power performance and driving range.

Microgenerator packaging is first and foremost designed to protect generators from physical damage, such as collisions, squashing and vibration, during transportation and storage. Because there are many precise parts inside the generator, such as rotors, stators, circuit boards, etc., these parts are easily damaged by external forces. Secondly, in order to prevent moisture and dust, to prevent external environmental factors from adversely affecting the performance of the generator. For example, a humid environment may cause the metal components inside the generator to rust, and dust may block heat dissipation channels or affect electrical insulation performance.

Carton: can easily print product information, identification and transportation precautions. The strength of the carton can be selected according to the weight and transportation requirements of the generator, and double-layer corrugated cartons are generally used to pack the micro generator. This kind of carton has good compression and puncture resistance, and can withstand a certain degree of pressure during stacking and handling.

Wooden box: For some micro-generators with longer distribution distances or higher protection requirements, wooden boxes will be used. The construction of wooden cases is stronger and can provide greater protection. Especially for export products or generators that need to be transported over long distances and in complex environments, wooden boxes can better withstand external pressure and collisions.

During the transportation process, to ensure the completeness of the transportation process and the safety of the equipment, do the following related work:

• Package inspection: Before shipping the generator, carefully check the package is in good condition. Make sure the inner packaging material (e.g., foam, bubble wrap) is tightly wrapped around the generator and is not loose or displaced. The outer packing (carton or wooden case) should be strong, tightly sealed, and the signs on the packaging (such as fragile sign, moisture proof sign, upward sign, etc.) should be clearly visible.
• Document preparation: Prepare relevant shipping documents, including product manuals, warranty cards, shipping lists, etc. If it is cross-border transportation, it is also necessary to prepare customs declaration documents, certificates of origin and other necessary documents.
• Fixed generator: If the generator is transported in a transport vehicle (such as a truck, a container), it needs to be fixed. Tools such as ropes and wooden wedges can be used to prevent the generator from being damaged by shaking and collision during transportation. For example, in the truck compartment, after the generator is placed in the right position, it is tied with the fixed point of the compartment with a rope to ensure that it does not shift during the vehicle.
