101. the method comprises the steps of acquiring the charge state of the lithium battery in real time, and judging whether the charge state meets a preset first charge condition.
In an embodiment of the present invention, the lithium battery is a lithium battery of an electric scooter, and the State of charge (SOC) is a value that reflects a remaining battery capacity of the lithium battery and is numerically defined as a ratio of the remaining capacity to a capacity of the battery unit, and is in a range of 0 to 1, where SOC is 0 indicating that the lithium battery is completely discharged, and SOC is 1 indicating that the battery is completely charged. The first charge condition is used for judging whether the state of charge of the lithium battery is healthy, for example, when the first charge condition is 0.3, the state of charge of the lithium battery is greater than 0.3, the lithium battery can be determined to be healthy, and when the state of charge of the lithium battery is less than or equal to 0.3, the lithium battery can be determined to be unhealthy. The state of charge can be estimated through parameters such as the terminal voltage of the lithium battery, the charging and discharging current, the internal resistance of a charging and discharging circuit and the like, and the estimation method can refer to the existing state of charge calculation method.
In a possible embodiment, the first charge condition may be set by the user, or may be determined according to a route set by the user. Specifically, the user can plan the riding route by setting a starting point and a target point, the return condition is considered according to the riding environment and the route of the route, the lithium battery consumption condition under the total route is estimated, and the default first charge condition is adjusted according to the lithium battery consumption condition. When the estimated lithium battery consumption condition is less than 80% of the lithium battery capacity, the default first charge condition can be adjusted down linearly, when the estimated lithium battery consumption condition is greater than 100% of the lithium battery capacity, the default first charge condition can be adjusted up linearly, when the estimated lithium battery consumption condition is greater than or equal to 120% of the lithium battery capacity, a user is prompted to be too long, and when the estimated lithium battery consumption condition is greater than or equal to 80% and less than or equal to 100%, the default first charge condition is not adjusted.
102. And if the charge state meets the preset first charge condition, entering a first control mode.
In the embodiment of the invention, the first control mode comprises the steps of obtaining the riding environment of the electric scooter, and controlling the lithium battery to discharge at a first preset current according to the riding environment, wherein the first preset current is a preference current for different riding environments.
The state of charge satisfying the preset first charge condition may be understood as that the state of charge of the current lithium battery is greater than a first charge threshold, for example, the state of charge of the current lithium battery is greater than the first charge threshold by 0.3.
Optionally, the above-mentioned environment of riding includes cross-country environment of riding, meadow environment of riding, sand ground environment of riding and highway environment of riding, and the above-mentioned environment of riding acquires or acquires through user's selection through image recognition technology.
Furthermore, images of the riding environment can be collected through a camera carried on the electric sliding plate, and then the current riding environment is classified according to a background recognition algorithm in an image recognition technology, so that the riding environment of the current electric sliding plate is obtained. Or, the user can make a selection on a preset riding environment key or interface, so that the current riding environment of the electric scooter is determined through the selection of the user.

The first predetermined electric current that the different environment of participating in selects corresponds can be different size, for example, the first predetermined electric current that the environment of riding of cross country corresponds can set up between 60A to 70A to make electric scooter acquire sufficient power, the first predetermined electric current that the environment of riding on meadow and the environment of riding on sand correspond can set up between 20A to 40A, the first predetermined electric current that the environment of riding on highway corresponds can set up between 8A to 15A. Different environments of riding represent different road surface conditions, and the first predetermined electric current of different environments of riding can represent the preference electric current of user under different environments of riding, and the preference electrofluid is on electric scooter, then preference speed, can understand that the first predetermined electric current of different environments of riding has represented the preference speed of user under different environments of riding.
In one possible embodiment, the user may be guided to determine the preferred speed in different riding environments, so that the preferred current in different riding environments is determined according to the preferred speed of the user in different riding environments. For example, after the cross-country riding environment guides the user to determine the preferred speed, the output current of the lithium battery corresponding to the preferred speed of the user in the cross-country riding environment is used as the preferred current of the user in the cross-country riding environment, that is, the first preset current of the cross-country riding environment. Similarly, other riding environments can also guide the user to determine preference speed, and then the preference current corresponding to the riding environment is determined according to the preference speed, so that the first preset current corresponding to each riding environment can be obtained.
It should be noted that, the speed of the electric scooter corresponding to the first preset current is the preference speed of the user, and after the riding environment of the user is obtained, the lithium battery can be controlled to discharge with the first preset current corresponding to the riding environment, so that the user does not need to adjust the speed state of the electric scooter, and the user experience is improved.

More specifically, since the self weight of the electric scooter is fixed, the minimum required speed is substantially related to the load of the electric scooter. For example, in the cross-country riding environment, when the load of the electric scooter is greater than a preset load value, the second preset current may be adjusted to linearly increase, and when the load of the electric scooter is less than the preset load value, the second preset current may be adjusted to linearly decrease. Specifically, the following formula can be used:
