The Evolution of Start-Stop Technology

Start-Stop technology has come a long way since its inception. Initially, it was limited to a few high-end vehicles, but it has now become a common feature in many cars. The primary goal of this technology is to reduce fuel consumption and lower emissions by minimizing the time the engine idles. As a result, the engine automatically shuts off when the vehicle comes to a complete stop, such as at traffic lights or in heavy traffic, and restarts quickly when the driver releases the brake pedal.

One of the key components of Start-Stop systems is the Start-Stop battery, which needs to meet specific requirements to handle the frequent cycling between charging and discharging. These batteries are designed to provide reliable power to start the engine multiple times during a single trip.
