Technical Field

[0001] This utility model belongs to the field of vehicle power technology, and in particular relates to a vehicle-mounted lithium-ion capacitor power supply device. Background Technology

[0002] Before the advent of supercapacitor bicycle technology, electric bicycles primarily relied on traditional battery technologies such as lithium-ion or lead-acid batteries. These batteries were typically used to store and release electrical energy to power the electric bicycle's motor. Here are some key features of electric bicycle technology:

[0003] Lithium battery technology: Lithium batteries are a commonly used type of battery in electric bicycles. They are characterized by high energy density and lightweight, and can provide a relatively long driving range. However, lithium batteries have disadvantages such as slow charging, poor low-temperature performance, and low safety.

[0004] Range and charging time: The range and charging time of traditional electric bicycles are limited by battery capacity and charging technology, and usually require a long charging time to obtain a longer range.

[0005] Traditional lithium battery-powered electric bicycle technology has some defects and shortcomings, including but not limited to:

[0006] The lithium batteries used in traditional electric bicycles have low safety. Under certain circumstances, such as overcharging, over-discharging, and external short circuits, there is a risk that the battery may catch fire or explode.

[0007] Short battery life: Traditional battery technologies such as lithium batteries have a limited number of charge-discharge cycles. Over time, the battery capacity will gradually decrease, resulting in a reduction in driving range.

[0008] Slow charging and discharging speed: Traditional electric bicycles typically charge relatively slowly, requiring a long time to complete the charging process, which affects the user experience and convenience.

[0009] Low energy recovery efficiency: Traditional electric bicycles have low energy recovery efficiency, meaning that kinetic energy cannot be effectively converted into electrical energy for storage during braking or coasting, resulting in energy waste.

[0010] Poor low-temperature performance: Lithium batteries suffer a significant performance drop at low temperatures, and may even become unusable.

[0011] Environmental friendliness: The battery materials and manufacturing processes used in traditional electric bicycles may have a certain impact on the environment. For example, battery recycling and disposal may cause environmental pollution problems.

[0012] Based on the shortcomings and defects of traditional electric bicycle power supplies, there is an urgent need to provide electric bicycles with power supplies that improve safety, extend battery life, accelerate charging and discharging speed, improve energy recovery efficiency, withstand high and low temperatures, have a long service life, and provide strong power output.
