Hybrid (Solid+ liquid) capacitor in HU application D head up display
Application description of HUD head up display in the whole vehicle:
HUD (head up display) is a scheme that allows the driver not to look down at the instrument and put important information on the windshield in front of the line of sight. In the future, with the configuration in MEB, it may be extended to more electric vehicles, and the market will be huge in the future.
■ HUD head up display function:
□ HUD shall connect complete data information with the vehicle system, integrate it into big data, and then map some important information to the window glass.
□ such as fuel consumption, fuel volume, speed, mileage, time, map navigation, etc.
□ the head up display increases convenience, enables our drivers to see the status information of the car more intuitively, and reduces driver fatigue.
❒ application of solid-liquid hybrid capacitor in HUD head up display:
■ application examples:
■ Hybrid capacitor function:
In automotive HUD head up display, 4-6 solid-liquid hybrid capacitors are generally used, which mainly play the role of filtering and energy storage, reduce EMI and EMS for the whole machine, and smooth output at the same time.
■ performance requirements:
□ low esr: when the whole machine is working, it has low heating, low noise and stable output.
□ wide temperature stability: ensure the normal energy storage function of the capacitor under various ambient temperatures.
□ shock resistance: ensure that the capacitor can work normally under various motion conditions.
□ broadband stability: within the broadband range, the capacitor energy storage function and filtering function can maintain a stable
