Battery Management System

1. Accurately estimate battery status: High-precision current sensors can provide accurate data basis for estimating battery state of charge (SOC) and state of health (SOH), helping users to more accurately understand the remaining battery power and battery health, and reasonably arrange travel and charging plans.

   
   

2. Optimize battery charge and discharge control: When charging, the high-precision current sensor can help the battery management system accurately control the charging current and time to prevent overcharging and extend battery life; when discharging, it can accurately monitor the discharge current to avoid excessive discharge of the battery.

   
   

3. Ensure safe operation of the battery: When the battery pack has abnormal current conditions such as overcurrent, short circuit, etc., the high-precision current sensor can detect it quickly and accurately, trigger the protection mechanism of the battery management system in time, cut off the circuit, prevent the battery pack from being damaged or even causing a safety accident.

Powertrain

1. Improve motor control accuracy: In power systems such as permanent magnet synchronous motors, high-precision current sensors monitor the current of each phase of the motor in real time and provide accurate current feedback signals for the motor control system, which helps to achieve more accurate vector control, speed regulation and torque control, making the motor output more stable and efficient.

   
   

2. Improve power system efficiency: Accurate current measurement allows the control system to accurately adjust the working state of the motor according to actual needs, so that the motor can operate in the high-efficiency range under different working conditions, reduce energy loss, improve the overall efficiency of the power system, and thus increase the range of electric vehicles.

   
   

3. Enhance system reliability and stability: High-precision current sensors can promptly detect current anomalies during motor operation, such as current fluctuations and imbalances. The control system can take corresponding measures, such as adjusting control strategies and issuing fault alarms, to avoid motor damage due to current problems and improve the reliability and stability of the power system.

Vehicle performance

1. Optimize the energy management system: The accurate current data provided by the high-precision current sensor can enable the energy management system to better coordinate the energy flow between various components such as batteries, motors, and charging systems, reasonably distribute energy, improve energy utilization, and enable electric vehicles to achieve optimal energy management under different driving conditions.

   
   

2. Improve driving experience: Due to the high precision of the current sensor, the power system responds more sensitively and the control is more precise. The vehicle's acceleration, deceleration, climbing and other operations will be smoother and smoother, and the power output will be more linear, bringing a better driving experience to the driver.

   
   

3. Assisting autonomous driving function: High-precision current sensors provide accurate current information for the autonomous driving system, which helps the autonomous driving system to more accurately judge the vehicle's power status and energy consumption, so as to more accurately plan the driving path, control the vehicle speed, adjust the driving strategy, etc., thereby improving the safety and reliability of autonomous driving.
