the preset maximum charge capacity may be 100% of the maximum allowable charge capacity of the battery or 99%/95% of the maximum charge capacity.

The maximum value of the charge capacity may be 90% of the maximum allowable charge capacity of the battery.

For example: a charging cut-off highest SOC (cut-off charging capacity) selection switch can be designed on a man-machine interaction screen so as to allow a user to select a range A-C%; c% is the maximum value of the charge capacity.

And 130, charging the electric automobile according to the selected target cut-off charging capacity.

Through the current state of automatic monitoring electric automobile, can send the suggestion to the user under charge state to automatic suggestion user selects to cut off charge capacity, then cut off charge capacity according to the target that the user selected charges to electric automobile, so, both can make the user select suitable charge electric quantity to satisfy individualized car demand such as many charging point electricity in order to satisfy long-distance car demand according to self demand, can ensure again that the cut off charge capacity of selecting is less than the battery shallow requirement of predetermineeing the biggest charge capacity all the time, has satisfied the battery shallow requirement of whole car factory promptly, avoids the new energy automobile battery to appear spontaneous combustion accident, ensures the safety in utilization of new energy automobile's battery.

In some embodiments, the method further comprises:

and if the target cut-off charging capacity is larger than a first preset charging capacity, sending out a charging safety alarm, wherein the first preset charging capacity is smaller than the maximum value, but is also larger, for example, the charging capacity reaches 80%.

In order to ensure the use safety of the battery of the new energy electric vehicle, the selectable target cut-off charging capacity of the new energy electric vehicle is not more than the first preset charging capacity by default, but the user may have long-distance vehicle requirements, so that the selected target cut-off charging capacity may be larger than the first preset charging capacity, and at the moment, a charging safety alarm can be automatically sent out for the safety of the battery, so that the user can carefully consider whether the larger cut-off charging capacity is selected, for example, a prompt 'for battery health, the charging cut-off SOC is suggested to be not higher than the first preset charging capacity' can appear on a man-machine interaction screen. "

In some embodiments, the method further comprises:

If the current state is restored to the non-charging state, the cut-off charging capacity can be automatically restored to the first preset charging capacity, so that the safe charging capacity is automatically restored to the non-charging state, and the safe charging capacity can be directly used in the next charging process. Of course, the user may not directly use the safe cut-off charging capacity but autonomously select an appropriate cut-off charging capacity at the next charging.

In addition, in the non-charging state, the charging interactive interface may not be prompted, so that the user cannot select to cut off the charging capacity.

In some embodiments, if the current state is restored to a non-charging state, prompting a selection to restore to an off-charge capacity that is not greater than the first preset charge capacity and not less than a second preset charge capacity, wherein the second preset charge capacity is less than the first preset charge capacity.

Of course, the user may not directly use the safe cut-off charging capacity but autonomously select an appropriate cut-off charging capacity at the next charging.

In some embodiments, the method further comprises:

monitoring the current total travel of the electric automobile;

In some embodiments, the maximum value of the truncated charge capacity is adjusted according to the probability of occurrence that the target truncated charge capacity is greater than the first preset charge capacity.

In some embodiments, the greater the probability of occurrence, the smaller the maximum value of the truncated charge capacity.

The technical scheme of the present disclosure will be further described below:

a selection switch for charging up to the highest SOC (battery charging capacity) is designed on a man-machine interaction screen, and the range A-C% can be selected;

when the charging gun is plugged in and plugged out again (in a non-charging condition), the charging is cut off to the highest SOC (battery charging capacity) and a switch default position B is selected; not being able to choose higher than B "during non-charging;

only during the vehicle charging process, the charging section can be selected to be higher than B% up to the highest SOC; however, if the charge intercept SOC selected in the charging condition is higher than B%, a prompt "for battery health is suggested that the charge intercept SOC is not higher than B" appears on the man-machine interaction screen. "

The value A < B < C, wherein B may decrease gradually in response to an increase in the total range of the vehicle. When the total driving range increases by D, then current B '=b-E (E corresponds to D, e=k× D k is a coefficient greater than 0 and less than 1), and (B' -a) ×d is less than the design maximum range of the vehicle, a being unchanged.

Wherein C can be reduced according to the occurrence probability of the charge cutoff SOC being higher than B, and C is not more than 100.

The user basically takes care of electric quantity before running for a long distance, and fully fills the electric quantity of the vehicle, and only the vehicle can autonomously set a charging cut-off SOC value in the charging process, and the vehicle can travel for a longer distance by setting a higher cut-off SOC value in the charging process. This does not affect the user's long distance driving experience.

After the charging gun is plugged in and pulled out again, the charging section is recovered to the default value B by SOC, so that the battery is healthy, and the spontaneous combustion probability of the battery is reduced.

The electric vehicle battery shallow charging system meets the shallow charging requirement of a vehicle enterprise as much as possible, meets the long-distance vehicle requirement of a user, and can effectively reduce market complaints caused by the fact that the vehicle enterprise is subjected to power locking after having a rest.
