  Laptop battery circuit and the role of protection circuit

  Its main function is power measurement. In addition, it also detects various parameters of the battery, such as voltage, current, temperature, etc., and also includes communication with the host. Through SMBUS or single bus, there are other information stored in the register, such as manufacturer information, compensation parameters, third-level termination voltage, etc. Some parameters are related to power measurement, and some chips also provide secondary protection control.

  For specific situations, you can read the data sheet in detail, which contains detailed instructions.

  S-8244 is an overcharge protection control chip for 3 or 4 series lithium-ion batteries. It is often used for secondary overcharge protection control. The output is often connected to a controlled temperature FUSE for overcharge protection.

  The usual overcharge protection is completed by the primary protection circuit. When the primary protection circuit fails, the secondary protection circuit can act to avoid safety problems caused by overcharging of the battery. Its protection is one-time. After the protection action, the battery cannot used, while basic overcharge protection is restorable.

  Note: The battery is most likely to be in danger when it is overcharged, so it requires secondary overcharge protection. Over-discharge will only damage the battery core, but will not cause safety problems.

  Laptop battery circuit diagram 2: The function of laptop battery protection circuit

  Someone asked online: "What kind of work does the laptop battery protection circuit do?" The following answers come from electrical professionals.

  If a laptop lithium battery is overcharged during charging, it may cause the battery to explode. If it is overdischarged, the battery will be damaged. In order to avoid these two states, it is generally necessary to add a protection circuit to the laptop battery, that is, a battery protection circuit board. .

  What does the battery protection circuit do:

  Simply put, it is "overcharge protection", "over-discharge protection", "overvoltage protection", "overcurrent protection", "temperature protection", etc.

  That is, it protects the charging and discharging of the battery to prevent overcharging, over-discharging, excessive charging and discharging current, excessive battery temperature and other charging and discharging states that are harmful to the battery.

  For details, see the image below:

  Basic architecture of laptop battery protection circuit board”

  First, the battery parameter acquisition circuit collects the battery's charge and discharge current, battery voltage and battery temperature, and sends these parameters to the central controller;

  The central controller makes judgments based on the preset thresholds of current, voltage and temperature;

  If the judgment result is the above illegal charging and discharging state, the Mos transistor connected in series with the main circuit is immediately turned off to cut off the charging and discharging circuit, thereby protecting the battery.
