Abstract
Description
[0001] Lithium battery installation technology field
[0002] The invention belongs to the technical field of lithium battery installation, and in particular relates to a lithium battery installation structure for an electric motorcycle. Background Art
[0003] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and a non-aqueous electrolyte solution.
[0004] An electric motorcycle is a motorcycle that uses electricity to drive it. It is environmentally friendly, energy-saving, and low-noise. The following is a detailed introduction to electric motorcycles: The working principle of an electric motorcycle is mainly to supply power to the motor through a battery pack, and the motor converts the electrical energy into mechanical energy, which in turn drives the motorcycle forward. Specifically, when the battery supplies power, the current passes through the coil of the motor, generating a magnetic field, which reacts with the magnetic field inside the motor to generate force, pushing the motor's rotor to rotate, and then driving the wheels to rotate, making the motorcycle move forward.
[0005] The disadvantages of the lithium battery installation structure of electric motorcycles can be expressed and summarized as follows:
[0006] Inadequate cooling system: Lithium batteries generate heat during use. If there is no effective cooling system (such as a water cooling system) in the battery pack, the battery temperature may exceed the safety threshold during long-term driving or fast charging, resulting in thermal runaway.
[0007] If the lithium battery installation structure of the electric motorcycle cannot be clamped, the stability is insufficient: If the lithium battery cannot be effectively clamped or fixed, the battery may shake or shift during the driving of the electric motorcycle, especially on bumpy roads or at high speeds. This will not only affect the stability and handling of the electric motorcycle, but may also cause damage to the battery itself. Safety hazards: If the lithium battery is not firmly clamped, it may rub or collide with other components due to vibration or collision, causing the battery casing to rupture or internal short circuit. This will greatly increase the risk of battery fire or explosion, posing a serious threat to the safety of the rider. Impact on battery life: When the battery works in an unstable state, it may be subject to additional stress and pressure, which will affect its performance and life. In the long run, the capacity of the battery will gradually decrease, the charging speed will also slow down, and eventually the battery may need to be replaced in advance.
[0008] If the lithium battery installation structure of an electric motorcycle lacks an anti-collision structure, its disadvantages are mainly manifested in the following aspects: Reduced safety: After the lithium battery without an anti-collision structure is installed, it is easy to be directly impacted when the electric motorcycle collides. This may cause the battery shell to rupture, internal short circuit, and even cause fire or explosion, posing a serious threat to the rider and surrounding people. When the lithium battery is hit, if there is no effective anti-collision structure to buffer it, the battery cell, electrolyte and other components inside the battery may be directly damaged, increasing the risk of battery fire or explosion.
