Embodiment

[0030] Example: such as figure 1 Shown; A wireless charging method for a car, which includes:

[0031] S1: Initialize;

[0032] S2: Determine whether the car can be charged, if so, charge it; otherwise, do not charge it.

[0033] S211: Determine whether the battery of the trolley is in reverse connection state;

[0034] S212: If yes, do not charge; if not, perform charging.

[0035] S221: If the battery of the trolley is not in the state of reverse connection, judge whether the voltage of the battery of the trolley is too low;

[0036] S222: If yes, perform precharging; if not, perform constant current charging.

[0037] S2221: When precharging, judge whether the battery voltage of the car returns to normal, that is, whether it is greater than U 0 ;

[0038] S2222: If not, return to step S2221; if yes, perform constant current charging.

[0039] S223: Carry out overcurrent protection for the battery being charged by constant current, and judge whether the charging volta...

Abstract

The invention discloses a wireless trolley charging method. The wireless trolley charging method comprises the steps that a trolley battery is initialized; it is judged whether a trolley needs to be charged or not, if yes, the trolley is charged, if not, the trolley is not charged. The wireless trolley charging method is low in cost, high in charging efficiency and wide in application range.

Description

technical field [0001] The invention relates to the technical field of wireless charging, in particular to a wireless charging method for a small car. Background technique [0002] With the rapid development of economy, energy saving, low carbon and environmental protection economy have become the needs of social development. In recent years, the sudden rise of electric vehicles has attracted widespread attention. Subsequently, in terms of power supply technology for electric vehicles, wireless charging technology is the development trend for future electric vehicle power supply. [0003] In real life, wired charging is still popular with the public. However, wireless charging has not been widely realized in life, but wired charging has the following disadvantages: the mobile handling of charging equipment and the lead wire of the power supply are too long, the manual operation is cumbersome, and the charging station and charging equipment The public area is too large, and ...
