Introduction to Button Battery Power Supply for Car Central Control System
Introduction to Button Battery Power Supply for Car Central Control System
In modern cars, the central control system is the core part of the vehicle's electronic control, responsible for managing functions such as in-vehicle entertainment, navigation, air conditioning, and window control. In order to ensure that these systems can still save key data (such as time, user settings, fault codes, etc.) after the vehicle is turned off, the car central control system usually requires a reliable backup power solution. Button batteries are ideal for car central control systems because of their small size, stability, and long life. Among them, BR2032 is a commonly used button battery model in car central control systems, and is favored for its high temperature resistance, superior storage performance, and wide range of applications.
Common Model: BR2032
BR2032 is a lithium-manganese dioxide button battery with a diameter of 20 mm, a thickness of 3.2 mm, and a nominal voltage of 3 volts. Compared with ordinary CR series batteries, BR series batteries use a special chemical formula to make them perform better in high temperature environments, which is very suitable for the harsh working environment of car central control systems.
Product Features
1. High temperature resistance
BR2032 batteries can work stably in a wide temperature range of -40°C to +85°C.
This feature makes it very suitable for car central control systems, because the internal ambient temperature of the car varies greatly, especially in summer or after long-term operation, the temperature inside the car may rise sharply.
2. Superior storage performance
BR2032 batteries have extremely low self-discharge rates, and the annual self-discharge rate is usually less than 2%.
Even if they are not used for a long time, the battery can still maintain sufficient power to ensure that the data of the car central control system will not be lost.
3. High energy density
BR2032 batteries have a high energy density and can provide long-lasting power support for the car central control system. The service life can usually reach 5-10 years.
4. Safe and reliable
BR2032 batteries adopt a sealed design with excellent anti-leakage performance to avoid damage to the precision electronic components of the car central control system due to battery leakage.
It complies with RoHS environmental protection standards, does not contain harmful substances such as mercury and cadmium, and is safe and environmentally friendly to use.
5. Wide range of applications
In addition to the car central control system, BR2032 batteries are also widely used in car key remote controls, tire pressure monitoring systems (TPMS), on-board diagnostic systems (OBD) and other scenarios.
Role in the car central control system
1. Real-time clock power supply
The BR2032 battery provides power for the real-time clock (RTC) of the car central control system to ensure that the time information is still accurate after the vehicle is turned off.
2. Data storage backup
When the vehicle is powered off, the BR2032 battery provides temporary power to the memory of the central control system to prevent the loss of important data such as user settings, navigation history, fault codes, etc.
3. Low-power operation support
When the vehicle is in sleep mode, the BR2032 battery provides power to the low-power module of the central control system to ensure that the system can wake up quickly and operate normally.
Application scenarios
1. In-car entertainment system
Save user's radio channels, sound settings and other information.
2. Navigation system
Store historical destinations, map preferences and other data.
3. Air conditioning control system
Records the user's personalized settings such as temperature and wind speed.
4. Window and seat control
Saves user preferences such as seat position and window height.
5. Car key remote control
Provides power to the electronic circuit of the remote control to achieve remote unlocking, starting and other functions.
Replacement and maintenance
1. Regular inspection
It is recommended to check the power of the BR2032 battery every 5 years to ensure its normal operation.
2. Correct replacement
When replacing the battery, make sure the vehicle is in a power-off state and replace the old battery with a battery of the same model.
3. Installation precautions
Pay attention to the positive and negative poles of the battery during installation to avoid short circuit or damage to the central control system.
The BR2032 button battery has become an ideal choice for the power solution of the car central control system with its high temperature resistance, excellent storage performance and wide range of applications. Whether in hot summer or cold winter, the BR2032 battery can provide stable and reliable power support for the car central control system, ensuring the normal operation of the vehicle electronic system and the safe storage of user data. Choose BR2032 battery to provide lasting power for your car's central control system!
