In order to improve the convenience of replacement of the power supply battery, the opening of the switch lock is generally controlled by a motor controller, the motor controller is a power consumption part and can normally work only when the power supply battery supplies power, and if the electric quantity of the power supply battery is exhausted, the power supply for the motor controller can not be continued, so that the motor controller can not work normally due to no electric quantity, the switch lock can not be controlled to be opened to complete the unlocking process, and when the battery needs to be replaced, a worker can need to unlock in other modes, therefore, the problem that the power supply battery is complex to replace is caused, and in order to solve the problem, the embodiment of the present application provides a battery management device, which will be elaborated in the following embodiment of the present application.
As shown in fig. 1, there is provided a battery management apparatus for an embodiment of the present application, including: a power supply battery 101, a switch lock 102, a motor controller 103 and a central controller 104.
In particular, the power supply battery may be a 36V power supply battery, which is used to power a motor controller for controlling some motor components on the electric vehicle, such as a switch lock for protecting the power supply battery.
The switch lock can be a motor lock, and the motor controller can control the switch lock to be opened when receiving an unlocking instruction, so that a worker can conveniently replace a power supply battery.
Specifically, the battery protection shell provided for the power supply battery may include a battery container and a battery cover, the battery cover and the battery container are connected through a switch lock, and when the switch lock is opened, a worker may open the battery cover to take out the power supply battery to be replaced from the battery container.
In order to perform over-discharge protection on a battery core of a power supply battery, generally, when the remaining power of the power supply battery is lower than a set low power threshold, the power supply battery does not output power to the outside, the low power threshold is generally set when the power supply battery leaves a factory, if it is detected that the remaining power of the power supply battery reaches a set threshold higher than the low power threshold, the power supply battery is disconnected to control the output power of a motor, when the power supply battery needs to be replaced, the power supply battery is recovered to control the output power of the motor, because the remaining power of the power supply battery is higher than the low power threshold, the power supply battery can also continue to supply power to a motor controller, and the power supply controller works normally, based on the idea, the following process is provided:
the central controller 104 is respectively connected with the motor controller 103 and the power supply battery 101, and is used for acquiring the residual capacity of the power supply battery 101, and disconnecting the output of the power supply battery 101 to the motor controller 103 when the residual capacity is smaller than a first set threshold; when receiving the unlocking instruction, the power supply battery 101 resumes the output of the electric quantity to the motor controller 103, and sends the unlocking instruction to the motor controller 103.
And the power supply battery 101 is used for supplying power to the motor controller 103.
And the motor controller 103 is connected with the switch lock 102 and is used for controlling the switch lock 102 to be opened when receiving an unlocking instruction.

The central controller 104 is further configured to send a battery replacement request to the user terminal and/or the background server through the communication component when detecting that the remaining power is less than the first set threshold.
For example, the above-mentioned electric power-assisted vehicle is applied to the sharing field, when the central controller detects that the remaining power of the power supply battery is less than a first set threshold, a battery replacement request may be sent to a background server of the sharing vehicle through the communication component, where the battery replacement request carries a model and a geographic position of a vehicle in which the power supply battery is located, and when the background server receives the battery replacement request, an area in which the power supply battery is located may be determined through the geographic position, and then a to-be-replaced instruction, which carries the geographic position of the power supply battery and the model of the vehicle in which the power supply battery is located, is sent to a mobile terminal of a worker corresponding to the area in which the power supply battery is located, so that the worker may go to the corresponding geographic position to replace the power supply battery when receiving.
Alternatively, the central controller may transmit the battery replacement command to a user terminal corresponding to the vehicle to which the power supply battery belongs through the communication means, and the user terminal may be a mobile terminal of a user of the vehicle to which the power supply battery belongs or a mobile terminal of a maintainer of the vehicle to which the power supply battery belongs.
Or, the central controller may also send a battery replacement instruction to the user terminal and the backend server corresponding to the vehicle to which the power supply battery belongs through the communication component, so that the backend server can learn the low power state of the power supply battery, and ensure the replacement speed of the power supply battery, for example, ensure that a person responsible for the vehicle to which the power supply battery belongs can be notified, thereby accelerating the previous replacement speed of the power supply battery.
In one embodiment, the motor controller is further configured to send switch lock opening feedback information to the central controller after determining that the switch lock is opened.
After the switch lock is opened, the motor controller can acquire the opening state of the switch lock, and then can send switch lock opening feedback information to the central controller after the determined switch lock is opened, so that the central controller can feed back the switch lock to the user terminal and/or the background server according to the opening information.

The central controller may store a second set threshold in advance, where the second set threshold is used to calibrate whether the power supply battery can continue to supply power to other power consuming components except the motor controller, for example, whether the power supply battery can supply power to a motor in an electric power assisted vehicle to which the power supply battery belongs, if the power supply battery is smaller than the second set threshold, the power supply battery cannot supply power to the motor any more, and when a user needs to use the electric power assisted vehicle, the central controller may control the prompting component to perform low power prompting to inform the user.
