Use the correct battery to protect the engine Start/Stop Engine technology

  • 26/03/2021

The technology automatically disconnects the engine temporarily has many different names depending on the car manufacturer, namely: i-Stop on Mazda cars, Eco Start/Stop on Mercedes cars or Start/Stop Engine on Toyota cars...

Currently, many new-generation cars are equipped with the function to automatically disconnect the engine when the car is stationary (pause) to save fuel and reduce emissions.
When activated, this technology will allow the engine to stop working (the vehicle stops waiting for a red light, stops at the curb, or when the vehicle changes gears (P), or the user removes the seat belt, etc. However, few people know that to be able to shut down the engine and quickly restart the ignition process quickly, cars with special battery requirements are equipped.
What is Start / Stop Engine Technology?
Engine start / stop is a common system in modern vehicles, temporarily stopping the engine while the vehicle is stopped to reduce fuel consumption and emissions. The engine is restarted when the clutch is applied or the brake is released, when the driver is ready to start moving again.

How does the Start / Stop Engine work?
The system uses a computer to detect when the vehicle is stationary or idling, then it controls the injection of fuel and stops the ignition in the combustion chamber. Ignition continues while the vehicle is in motion or the clutch operates.
This process is automatic, but the driver can intervene so that when the system is activated or not by pressing a button on the dashboard, usually with the symbol A with the upper hook rotating clockwise. clock.
Normally, a set of gears with an engine spring will start, which will restart the engine as soon as the computer detects that the wheelchair or clutch is working. With the development of technology, the start-up engines of automobile engines gradually increase their power and operate faster, helping to minimize rolling delay when braking.
Disadvantages of Start / Stop Engine technology
In terms of engine durability and longevity, relevant factors would include the starter device, with the engine shutoff system, the number of starts several times a motor without a system. this.
According to the experience of a self-driving car rental unit in Da Nang like us, with a normal car that does not use the engine shutoff system, it can perform the start-up process about 50,000 times. during the life of that engine, but with the engine shutoff system equipped, its start times can reach up to 500000 times in its lifetime. of the engine. This poses challenges in the durability and longevity of engine bearings.
In fact, most car users have the basic knowledge that cars drive in the city with a constant explosion frequency (very large current required) while the continuous running time is rarely A full charge will cause the battery to burn rapidly. With vehicles fitted with technology that suspends the engine when not loaded, the explosion density increases dramatically, causing the battery to bear more load, reducing life expectancy.
In addition, when the engine is temporarily switched off, many car parts, including the new generation air conditioners or headlights, still need maintenance. These devices require high constant current, thought to be powered by the vehicle's generator, which now relies on batteries.
Meanwhile, traditional car batteries are only designed to power a vehicle ignition several times a day and power some basic electrical equipment that doesn't require a lot of energy (like the Insufficient to meet the requirements of the new motor shutoff technology.
As a result, models that are able to stop engines often require the use of sealed batteries with pressure valves called AGM (Absorbent Glass Mat). In the past, this type of battery was often used limited in the maritime and telecommunications sectors ... due to its high cost. This is also the reason why AGM batteries are sometimes called telecommunications batteries by experts in Vietnam.
While using the same lead-acid technology platform as traditional batteries, their distinct construction allows AGM batteries to excel in power / storage stability and can be fully charged much faster. times and withstand the state of high current. This feature allows it to meet the electrical needs of modern cars.

Using AGM batteries not only guarantees its own durability, but also helps reduce wear and tear for many automotive parts, including generators and drivers. More importantly, if vehicles require the use of AGM batteries but are fitted with batteries, they can often experience sudden battery failure, leading to many risks during use. In case of operation, the vehicle may not be able to start the engine, need to be assisted by hospital.
In a bad situation, turning off the air conditioning system in harsh sunlight or when the temperature is too low can have fatal consequences. For this reason, some high-end models may proactively alert or disable certain features when the installed battery type is deemed inappropriate.
To know if your vehicle requires AGM battery, the user should refer to the manual supplied with the vehicle or contact the manufacturer. For its part, AGM batteries are usually clearly stated on the label. Vehicles without AGM batteries can still use these batteries normally, but this is unnecessary waste as the price of AGM batteries is usually 1.5 to two times higher than traditional batteries.
In Vietnam today, AGM batteries are popular with capacities from 70 Ah to 95 Ah, corresponding to the selling price of 4.5 million to more than 5 million VND. Meanwhile, prices for traditional batteries of the same capacity range from over one million dong to 2.5 million dong.
