[0021] The present invention will be described in further detail below with reference to the accompanying drawings.
[0022] like Figure 1As shown, an intelligent battery management device includes a battery 1 and an electronic product 2. The battery 1 is provided with a battery protection board 3, a battery information chip 4 is provided on the battery protection board 3, and a battery information identification chip 5 is built into the electronic product 2. The battery information identification chip 5 is electrically connected to the battery information chip 4 and is configured to read and identify information stored in the battery information chip 4 and adjust the battery management strategy based on the identification results. By integrating the intelligent battery protection board 3 with the battery information chip 4 and the battery information identification chip 5 within the electronic product 2, the present invention achieves automatic identification and intelligent matching of battery information, effectively improving battery safety and compatibility, extending the service life of the battery and electronic product 2, and providing convenient battery replacement guidance.
[0023] Specifically, in this embodiment, the battery information chip 4 stores information about the battery capacity, maximum charging voltage, maximum charging current, standard charging current, and maximum discharge current. It should be noted that the battery information chip 4 stores detailed battery parameters, including but not limited to battery capacity, maximum charging voltage, maximum charging current, standard charging current, and maximum discharge current. It should be noted that the battery information identification chip 5 is used to read and analyze the contents of the battery information chip 4 on the battery protection board 3, automatically determining the degree of compatibility between the new battery and the original requirements of the electronic product 2.
[0024] Specifically, in this embodiment, the battery protection board 3 is electrically connected to the positive and negative electrodes of the battery 1 .
[0025] Specifically, in this embodiment, when the battery information identified by the battery information identification chip 5 completely matches the original requirements of the electronic product, the electronic product 2 controls the battery to operate according to normal parameters.
[0026] Specifically, in this embodiment, when the battery information identified by the battery information identification chip 5 does not match the original requirements of the electronic product, the electronic product 2 automatically adjusts the battery operating parameters to the minimum safety value and prompts the user that the battery information does not match.
[0027] Specifically, in this embodiment, when the battery information identified by the battery information identification chip 5 does not match the original requirements of the electronic product at all, the electronic product 2 controls the battery to operate at minimum power and not exceeding the maximum charging voltage marked on the battery, and issues a battery replacement prompt.
[0028] In summary, the intelligent matching and protection mechanism of the present invention is:
[0029] Exact match: When the identified battery information is completely consistent with the original requirements of the electronic product 2, the battery operates according to normal parameters to ensure optimal performance and safety.
[0030] Partial match: If the battery information does not match, the system will automatically adjust to the minimum safety parameters (such as minimum charging current and minimum discharging current) and prompt the user on the electronic product 2 interface that the battery information does not match, suggesting that the battery be replaced with a compatible one.
[0031] Mismatch: If the battery information does not meet the requirements of electronic product 2 at all, the system will control the battery to charge and discharge at the minimum power (not exceeding the maximum charging voltage marked on the battery), and at the same time prompt the user to replace the battery immediately through visual or sound.
[0032] Specifically, in this embodiment, the electronic product 2 sends a battery status prompt to the user through visual or sound signals.
[0033] Specifically, in this embodiment, the battery protection board 3 uses the power management chip S-8254A. It should be noted that the specific design of the battery protection board 3 includes the following structures:
[0034] Core control component: Choose a high-performance power management chip, such as the S-8254A. The power management chip S-8254A is responsible for receiving sensor signals such as voltage, current, and temperature, and making judgments and controls based on preset protection strategies.
[0035] Voltage detection circuit: This circuit reduces the lithium battery pack voltage to within the acceptable range of the chip through a voltage divider circuit and inputs it to the chip's voltage detection pin. The chip has an internal voltage threshold. When the voltage exceeds or falls below the threshold, overcharge or over-discharge protection is triggered.
[0036] Current detection circuit: This uses components such as Hall sensors or shunt resistors to convert the lithium battery pack's current into a voltage signal, which is then fed into the chip's current detection pin. The chip has an internal current threshold; when the current exceeds the threshold, overcurrent protection is triggered.
[0037] Temperature detection circuit: Using components such as a thermistor or NTC temperature sensor, the temperature of the lithium battery pack is converted into a voltage signal and input into the temperature detection pin of the chip. The chip has an internal temperature threshold. When the temperature exceeds the threshold, overheat protection is triggered.
[0038] Protection output circuit: The chip controls the on / off switching of components such as MOSFETs in the protection output circuit based on sensor signals such as voltage, current, and temperature, thereby protecting the lithium-ion battery pack. If an abnormality is detected, the chip disconnects the MOSFETs, severing the connection between the lithium-ion battery pack and the load, preventing battery damage or potential safety incidents.
[0039] It should be noted that the power management chip is responsible for receiving sensor signals and making judgments and controls, and is the core component of the protection board.
[0040] Voltage, current and temperature sensors: used to detect the voltage, current and temperature of the lithium battery pack respectively, and convert the signals into voltage signals acceptable to the chip.
[0041] MOS tube: used to control the connection and disconnection between the lithium battery pack and the load to achieve control of the protection output circuit.
[0042] Auxiliary circuits such as voltage divider circuits and filter circuits are used to preprocess and filter sensor signals to improve signal accuracy and stability.
[0043] The utility model sets a battery information chip 4 in the battery protection board 3, which contains information such as the battery capacity, maximum charging voltage, maximum charging current, standard charging current, and maximum discharge current, and a battery information identification chip 5 is built into the electronic product 2. After replacing the battery, the electronic product 2 automatically reads and identifies the battery information. When it meets the original requirements of the electronic product 2, the battery is completed and can operate normally. When the electronic product 2 identifies that the battery information does not match, the battery is controlled to operate with minimum parameters or a prompt is given to replace the battery. When the electronic product 2 identification is not satisfied, the battery charging and discharging will be controlled to operate with minimum power and according to the maximum charging voltage marked on the battery, the battery will be matched with the minimum power, and a prompt will be given to replace the battery. The utility model realizes automatic identification and intelligent matching of battery information through the intelligent battery protection board 3 with integrated battery information chip 4 and the battery information identification chip 5 in the electronic product 2, effectively improving the safety and compatibility of battery use, extending the service life of the battery and the electronic product 2, and providing convenient battery replacement guidance.
