Abstract

A composite power supply. Including micro control unit, battery voltage detection module, super capacitor voltage detection module, DC conversion module, current detection module, signal amplification module, voltage regulator module, super capacitor and battery. The micro-control unit processes the status signal according to the preset parameters, sends control commands to the DC conversion module, adjusts the output frequency and duty cycle of the DC conversion module, and controls the output power of the super capacitor and the output power of the battery; its purpose is to improve the electric motor Bicycle launch, acceleration, climbing performance. Avoid high-current charging and discharging of the battery alone, reduce damage to the battery, and improve the service life of the battery. Provided is a method for controlling the output power of the composite power supply of the present invention, which controls the composite power supply to provide electric power for electric bicycles to achieve high-speed and long-term running.

Description

technical field

[0001] The invention relates to a power supply device and a control method thereof, in particular to a compound power supply for an electric bicycle and a control method thereof. Background technique

[0002] With the development of battery technology, colloidal lead-acid batteries, nickel-metal hydride batteries and lithium-ion batteries have emerged. Compared with lead-acid batteries, these types of batteries have better performance, less pollution to the environment, and avoid secondary pollution. However, due to its stable performance, high quality and low price, lead-acid batteries will occupy the majority market share for a long time in the future. For example, in the domestic electric bicycle market, lead-acid batteries are basically used as energy sources for power supply.

[0003] The plate of the battery is composed of lead and lead oxide, and the electrolyte is an aqueous solution of sulfuric acid, which will cause great pollution to the environme...
