There are some differences in communication between the SOC (State of Charge) on the controller and the battery.
< br >
1. SOC communication: The SOC on the controller usually refers to the combined power percentage of all individual batteries in the battery pack. The controller periodically reads the charge from each cell and calculates the total SOC value. This value can be used to monitor the status of the battery pack and predict the remaining range. In the communication process, the controller sends a read request to the battery, receives the current status information of each cell, and then calculates the total SOC value.

2. Battery communication: Different from this, the communication between the controller and the battery is more involved in real-time monitoring and regulating the battery charge and discharge. In the communication process, the controller reads the temperature, pressure, capacity and other parameters of each battery to detect the battery status, and adjusts the charging and discharging rate and other parameters as required to ensure safety and optimal performance.

While the two methods of communication are different, they are both necessary components to ensure that the overall electric vehicle system works well.
There is no direct communication between the SOC on the controller and the battery. In the field of industrial automation, the SOC on the controller refers to the chip or module with components such as processor, memory, input and output interfaces, which is used to realize the calculation and data processing functions of the controller. The battery is used as a source of power supply for the device, which is mainly used to store energy to provide independent and repeatable energy for the system.

Therefore, the SOC and battery on the controller correspond to different hardware components, the main difference is the function and use, and there is no direct communication.
There are the following differences:
< br >
1. Different communication methods: the SoC obtains the battery status through the chip on the controller, while the battery manages and monitors the battery status through the battery management system (BMS).

2. Different monitoring objects: SoC mainly monitors the charging state of the battery, that is, the percentage of electricity remaining in the battery. The battery management system will monitor various parameters of the battery, such as voltage, temperature, current, etc., to ensure the safe and stable operation of the battery.

3. Different communication frequency: SoC communication frequency is usually relatively low, generally every few minutes or hours will be updated. The battery management system needs to monitor the battery status in real time, the communication frequency is relatively high, and the battery status can be updated in real time.
