ARM-based universal smart charger for electric bicycles and its method

Abstract

The invention provides a general electric bicycle intelligent charger based on an ARM. The charger comprises an ARM main controller, a detection circuit, a control circuit, a power supply module, a step-down transformer, a controllable rectifying circuit, a filtering voltage stabilizing circuit and a storage chip. The ARM main controller is respectively connected with the detection circuit, the control circuit and the storage chip; the control circuit is respectively connected with the controllable rectifying circuit and the filtering voltage stabilizing circuit; the controllable rectifying circuit is respectively connected with the step-down transformer and the filtering voltage stabilizing circuit; the step-down transformer is connected with the power supply module; the detection circuit, the control circuit and the filtering voltage stabilizing circuit are all connected with a storage battery; and the storage chip is mounted in the storage battery. The invention also provides a general electric bicycle intelligent charging method based on the ARM. The charger is generalized; the resources are saved; and the charger is convenient for people to get around.

Description

Technical field [0001] The invention relates to the application field of power electronics, in particular to an ARM-based general intelligent charger for electric bicycles and a method thereof. Background technique [0002] Since France trial-produced electric vehicles using lead-acid batteries as a power source in 1881, countries around the world have continuously made new breakthroughs in the research of electric vehicles. Since the 20th century, especially after the Second World War, countries around the world have vigorously advocated the development of electric vehicles, and electric bicycles have been greatly promoted and used with their unique advantages. Electric bicycles have become the direction of transportation upgrades due to their advantages such as low pollution, energy saving, simple structure and control, easy operation and maintenance. [0003] Now, with the rise of oil prices and people's awareness of environmental protection, electric bicycles are becoming more...

Problems solved by technology

However, electric bicycles also have shortcomings such as frequent charging and regular battery replacement.

[0004] Nowadays, many families have more than one electric bicycle, but because there are many electric bicycle manufacturers and there are many types of battery models, electric bicycle chargers of different manufacturers and different battery models cannot be used universally.

At present, the output current and voltage adjustment range of electric bicycle chargers on the market are very narrow, and they are only suitable for specific loads. Generally, a charger can only charge the same type of battery from the same manufacturer, which has resulted in differences between various types of electric bicycles. The closure of the room has caused inconvenience to consumers who own more than one electric bicycle at the same time

When an electric bicycle is broken, its charger is useless, and the charger of an electric bicycle is damaged, and other models of chargers cannot be replaced. Even after the electric bicycle is replaced with a new battery, the original The charger can no longer be used

This creates a certain degree of waste invisibly

At the same time, because the charger is not universal, people need to carry the charger with them when they go out. However, there are potentiometers on the internal circuit board of the existing chargers, which cannot withstand the long-term vibration and bumps during driving, otherwise the internal potential will be changed. The resistance of the charger makes the charger prone to failure, which undoubtedly brings great inconvenience to people's life and travel.

[0005] Therefore, the chargers of electric bicycles cannot be standardized, and electric bicycle chargers of different manufacturers and models cannot be used universally. This problem has just become a problem that those skilled in the art want to overcome.
