Batterie start-stop de voiture de grande capacité d'usine 12.8V 165Ah

Applicable models:

New Audi A4L, Audi A5, Audi TT, Audi Q5 (including domestic models), Baoan 5 Series, Volkswagen Phaeton, etc.

Advantages of 12.8V 165Ah large-capacity car start-stop battery:

1. Super long life

The cycle life of lead-acid batteries is generally 250~300 times, and the cycle life of this lithium iron phosphate battery is about 3000 times. If the vehicle is parked for a long time without starting, the battery of the car will be exhausted, and the lead-acid battery will be scrapped. The lithium iron phosphate battery can still be used normally after charging without affecting its lifespan.

2. Ensure safety

The main component of lithium iron phosphate battery is iron, which is not easy to catch fire and explode just like the main component of lead-acid battery is lead.

3. Improve power and reduce fuel consumption

The internal resistance of the battery is low, the output current is large, the electric spark of the spark plug is large, the ignition speed is fast, and the fuel is fully burned. The peak horsepower is increased by about 4.5%, and the peak torque is increased by about 3%. The fuel consumption of lithium iron phosphate batteries is 5% lower than that of lead-acid batteries.

4. High energy density
The same volume of lithium iron phosphate has 50% more capacity than lead acid, and the same volume of lithium iron phosphate has 70% less weight than lead acid.

5. Good high temperature performance

The electric heating peak of lithium iron phosphate can reach 350°C~500°C.

Lithium manganese oxide and lithium cobalt oxide are around 200°C.

The operating temperature range of lithium iron phosphate is -20°C~80°C.

The working temperature range of lead-acid batteries is -20°C~50°C.

6. Reduce vehicle weight

Lithium iron phosphate batteries weigh 70% less than lead-acid batteries, and the reduced weight allows cars to accelerate faster and consume less fuel.

7. Improve sound quality

The internal resistance of the battery is low, and the transient output power is large, which fully meets the stringent requirements for instantaneous high-current power supply when the audio is large and dynamic, making the mid-bass thicker and the treble more transparent

8. Scientific environmental protection

Lithium iron phosphate battery does not contain heavy metals and rare metals, non-toxic, non-polluting, in line with European RoHS regulations, waste batteries can be recycled and reused

9. Safe and reliable

Built-in intelligent BMS management system, with multiple protection functions such as overcharge, overdischarge, overcurrent, overvoltage, overtemperature, overload, short circuit protection, etc., to avoid battery damage caused by overcharge and overdischarge, and durable.

Why Traditional Starter Batteries (SLI) Are Not Enough for the Start-Stop Needs of Modern Vehicles:

Every start-up process involves a lot of energy from the car’s battery. The battery must be in very good condition to reliably deliver high cranking currents. Especially with modern vehicles equipped with automatic start-stop systems, the engine will be shut down several times while driving. During these phases, the battery continues to provide energy to all electrical devices. Traditional starting batteries (SLI) are not designed for this charge output (i.e. continuous discharge and charge). Only a battery with start-stop technology can meet these demands and withstand the stress.

In cars not equipped with automatic start-stop systems, the start-up process is usually a one-off event. During the driving process, the generator supplies power to the entertainment system, navigation equipment and other electrical equipment, so when the generator is working, the starting battery will not be discharged during driving.

For cars with stop-start technology, the situation is different. During a trip across town, the battery goes through a series of start and stop cycles. If a car is stopped at a traffic light and the engine is stopped, appliances such as lights, windshield wipers, radios or monitors still need power. Increase the load by continuously discharging and charging.

Short trips in particular present a challenge for the battery. Especially with old batteries and in winter, the charging acceptance of the battery will be reduced, so a sufficient charge cannot be guaranteed during short trips. This causes the battery to gradually discharge to the point that at some point, the battery no longer has enough energy to start the engine. Due to the use of special technology, the internal resistance of the lithium iron phosphate start-stop battery is much lower than that of traditional batteries throughout its lifespan, so it can ensure sufficient charging acceptance for a long time and better cope with multiple start-stop stages. excursions.
