Referring to fig. 1, a preferred embodiment of the present invention provides a power-up and power-down control method applied to a Battery Management System (BMS), wherein the BMS includes a charged Erasable Programmable read only memory (EEPROM) chip and a pluggable memory device, and the BMS is a "new BMS" described below. The pluggable memory device stores therein history data information of the BMS, and when the BMS is replaced due to a failure or other reasons, a worker removes the pluggable memory device from the replaced BMS and inserts the pluggable memory device into a new BMS.

The pluggable storage device may be a Secure Digital Memory Card (SD Card) or other storage devices with pluggable, readable, and writable functions.

Fig. 1 includes the following steps:

s101: and acquiring a power-on indication signal.

The power-on and power-off control method provided by the invention can be applied to a controller, and the controller can be a microcontroller MCU in the BMS or other controllers different from the MCU. The controller acquires the power-on signal through a power-on instruction sent by the whole vehicle controller.

S102: and responding to the power-on indication signal to determine a power-on mode.

The power-up modes include, but are not limited to: after-sale power-on, production line power-on and normal power-on.

Further, determining the power-up mode comprises: reading preset zone bit information; and when the preset zone bit information is a first numerical value, determining that the power-on mode is after-sales power-on.

The preset flag bit information may be a numerical value or a character corresponding to the preset flag bit, and the power-on modes corresponding to the preset flag bit information are set when the BMS leaves a factory. For example, when the preset flag bit information is a first numerical value, it indicates that the corresponding power-on mode is after-sales power-on; when the preset zone bit information is a second numerical value, the corresponding power-on mode is power-on of a production line; and when the preset zone bit information is a third numerical value, indicating that the corresponding power-on mode is normal power-on.

Further, the controller may read the flag bit information, and when the controller reads that the preset flag bit information is the first numerical value, it may determine that the power-on mode is after-market power-on, and then execute S103.

S103: and when the power-on mode is after-sales power-on, reading the stored data stored in the pluggable storage device and writing the stored data into the EEPROM chip.

The after-sale power-on is a general term, and can also be replaced by maintenance power-on, maintenance power-on or other names with similar meanings. The after-market power-up may include, but is not limited to, the following: the BMS fails to be replaced and the BMS is aged and needs to be replaced.

As described above, when the power-on mode is after-market power-on, that is, the BMS is replaced, the worker removes the pluggable memory device from the replaced BMS and inserts the pluggable memory device into the new BMS, wherein the stored data in the pluggable memory device is history data in the BMS before the replacement. Optionally, the storage data stored in the pluggable storage device comprises at least one of: the method comprises the following steps of battery pack manufacturing information, battery pack historical fault information, battery pack historical charging frequency information and battery health degree SOH information. When a new BMS is replaced, the controller reads the storage data stored in the pluggable storage device and writes the storage data into the EEPROM chip. The controller reads the stored data stored in the pluggable storage device and writes the stored data into the EEPROM chip, so that the data of the historical data of the BMS before replacement on the new BMS after replacement is updated, and a series of problems caused by inaccurate historical data on the new BMS due to the fact that the historical data cannot be updated are avoided. For example, the driver cannot accurately grasp the driving range information of the vehicle, so that the vehicle cannot arrive at the destination or be charged in time, and the driving experience is reduced.

The stored data including the battery pack history charging number information and the battery health SOH information will be described below.

The controller can accurately prompt the driving mileage information of the vehicle under different battery electric quantities according to the SOH information of the battery health degree. The driver passes through the mileage information of continuing a journey can be in when the electric quantity of battery package is less than preset electric quantity value, in time be the battery package charges, avoids the vehicle is in the long time travel when the electric quantity of battery package is less than preset electric quantity value leads to battery package insufficient voltage, and then influences the life of battery package. And the driver judges whether the electric quantity needs to be supplemented to the vehicle in advance according to the driving mileage information and the distance between the driver and the destination to be approached, so that the situation that the vehicle cannot reach the destination due to insufficient electric quantity in the driving process is avoided, and the driving experience is reduced.

The controller can be right according to battery package historical charging number of times information, can monitor the current life of battery package, when the historical charging number of times information of battery package reaches and predetermines the number of times of charging, the controller can indicate through display device on the vehicle to remind the driver to be right the battery package is changed, in order to avoid influencing the continuation of the journey mileage of vehicle.

Further, when the power-on mode determined in S102 is on-line power-on, the controller writes the manufacturing information of the battery pack into the EEPROM chip.

For example, when the information in S102 is the second value, it is determined that the power-up mode is line power-up. The power-on of the production line is a general term, and can also be summarized by power-on of production, power-on of factory or other names with similar meanings. When the power-on mode is power-on of a production line, the controller writes the manufacturing information of the battery pack into the EEPROM chip, so that when subsequent workers maintain or overhaul vehicles, the specific conditions of the battery pack can be mastered by checking the manufacturing information of the battery pack, and the service time, the service life or other indexes of the battery pack can be monitored.

Further, after writing the storage data to the EEPROM chip and writing the manufacturing information of the battery pack into the EEPROM chip, the method further includes: the power-up mode is set to normal power-up. Specifically, the preset flag bit information may be set to a third numerical value; the third value is used for indicating that the power-on mode is normal power-on. For example, the third value may be updated by the first value or the second value.

The controller may change the power-on mode from the after-sales power-on mode or the production line power-on mode to the normal power-on mode by setting the preset flag bit information to a third value for indicating that the power-on mode is the normal power-on mode, and the BMS may normally operate when the power-on mode is the normal power-on mode.

Further, when the power-on mode determined in S102 is normal power-on, data information in the EEPROM chip is read.

And when the controller finishes reading the data information in the EEPROM chip, the controller detects the state of the battery pack and acquires the current battery pack data information.

On the basis of each of the steps described above, the controller is further configured to:

acquiring a power-off indicating signal;

responding to the power-off indication signal, and updating the current battery pack data information;

writing long-period data and short-period data in the battery pack data information into the EEPROM chip, and writing the long-period data into the pluggable storage device;

and executing a power-off process.

Wherein the long-period data includes, but is not limited to, battery pack fault information, battery pack charging number information, and battery health SOH information; the short-period data includes, but is not limited to, battery pack voltage information, cell voltage information, and insulation resistance information at power-on. By writing the long-period data and the short-period data in the battery pack data information into the EEPROM chip, when the vehicle is restarted, the controller can reacquire the long-period data and the short-period data, so that the state of the battery pack is effectively monitored and effectively prompted. The long-period data in the battery pack data information is written into the pluggable storage device, so that the long-period data can be backed up. When the BMS breaks down and needs to be replaced, a worker can install the pluggable storage device on the replaced new BMS, so that the long-period data can be updated on the replaced new BMS, a series of problems caused by the fact that the long-period data cannot be updated are avoided, for example, the driving mileage of a vehicle cannot be accurately prompted, and the driving experience of a driver is reduced.

Next, the controller is taken as a Micro Control Unit (MCU) in the BMS, and the pluggable memory device is an SD Card for example.

As shown in FIG. 2, compared with the prior art, the present invention adds a circuit for connecting the MCU and the SD Card. In the figure, "W" represents writing, "R" represents reading, and the MCU can communicate with the EEPROM and the SD Card. When the power is on, the MCU can read the data in the EEPROM or the SD Card, and when the power is off, the MCU can respectively write the updated data into the EEPROM and the SD Card, thereby realizing the backup of the data in the EEPROM by the SD Card. When the BMS malfunctions and needs to be replaced, a worker may remove the SD Card from the BMS before the replacement and install the SD Card in a new BMS. And when the MCU determines that the power-on mode is after-sale power-on, the data of the SD Card can be read and written into the EEPROM, so that the data updating is realized. Therefore, the accuracy of the historical data in the BMS can be ensured, the problems caused by the inaccuracy of the historical data, such as the inaccuracy of the driving mileage of the vehicle, can be avoided, so that a driver can not accurately master the real driving mileage information of the vehicle, the driver can not arrive at a destination or charge the vehicle in time in the driving process of the vehicle, and the driving experience is reduced.

Further, referring to fig. 3, the operation performed by the MCU during power-on will be described in detail.

In fig. 3, "BMS _ MODE" indicates the preset flag bit information of the BMS, "AS" indicates after-market power-up, "Line" indicates on-Line power-up, and "Normal" indicates Normal power-up. When the MCU acquires a power-on instruction, the MCU can judge that the current power-on mode is one of after-sale power-on, production line power-on or normal power-on according to the preset zone bit information of the BMS. When the MCU acquires that the preset zone bit information of the BMS is a third numerical value, the current power-on mode can be determined to be normal power-on, wherein the normal power-on is used for quitting power-on of a production line or after-sales power-on, the normal power-on can be entered by one-way skip of the power-on of the production line or the after-sales power-on, and then the MCU reads data information in an EEPROM; when the MCU acquires that the preset flag bit information of the BMS is a second value, the current power-on mode can be determined as power-on-line, wherein the BMS on the production line is provided with an SD Card for mass production of normal battery packs, the MCU writes the manufacturing information of the battery packs into the EEPROM, and when the MCU finishes writing the manufacturing information of the battery packs into the EEPROM, the MCU sets the preset flag bit information as a third value for indicating that the power-on mode is normal power-on from the second value, namely, the power-on mode of the BMS is changed into normal power-on; when the MCU acquires that the preset zone bit information of the BMS is a first numerical value, the current power-on mode can be determined to be after-sales power-on, wherein after-sales power-on the BMS does not have an SD Card for maintenance and use of a fault battery pack, the MCU reads data in the SD Card, the data in the SD Card is data in the BMS before replacement, and the data in the SD Card can comprise battery pack manufacturing information, battery pack historical fault information, battery pack historical charging frequency information and battery health degree (SOH) information. And when the MCU reads the data in the SD Card, writing the battery pack manufacturing information, the battery pack historical fault information, the battery pack historical charging time information and the SOH information into the EEPROM. And when the MCU finishes writing the data in the SD Card into the EEPROM, the MCU sets the preset flag bit information as a third numerical value for indicating that the power-on mode is normal power-on from a first numerical value, namely the power-on mode of the BMS is changed into normal power-on. When the power-on mode of the BMS is normal power-on, the BMS may detect a state of a battery pack, acquire and update short-cycle data, and execute a corresponding instruction according to the state of the battery pack and a Vehicle Control Unit (VCU) state machine.

Further, referring to fig. 4, the operation performed by the MCU during power-down will be described in detail.

When the MCU acquires a power-off instruction, the MCU can update the long-period data and the short-period data of the battery pack according to the running state of the battery pack and write the updated long-period data and the updated short-period data of the battery pack into the EEPROM, and when the MCU finishes writing the updated long-period data and the updated short-period data of the battery pack into the EEPROM, the MCU can write the updated long-period data of the battery pack into the SD Card. And the MCU executes power-off operation when the updated long-period data of the battery pack are written into the SD Card, namely the BMS finishes power-off.

Based on the same technical concept as the above power-on and power-off control method, as shown in fig. 5, another preferred embodiment of the present invention further provides a power-on and power-off control device applied to a battery management system BMS, wherein the BMS includes a EEPROM chip and a pluggable memory device.
