New Braking System will Revolutionise Electric Cars



New Braking System will Revolutionise Electric Cars

An innovative breakthrough from ZF could potentially revolutionize the dynamics of hybrid and electric vehicles by eliminating conventional fluid-based systems.


Steering-by-wire and shift-by-wire technologies, which manage steering and transmission electronically rather than mechanically and hydraulically, have been gaining substantial attention. This interest has amplified, especially with the advent of software-defined vehicles and the prominence of electric cars in the automotive landscape.

Now, a new frontier is on the horizon: brake-by-wire, a groundbreaking technology set to enable fully electronic brake adjustments. ZF, a trailblazer renowned for its automatic transmissions, has introduced a groundbreaking electromechanical braking system that fundamentally diverges from the traditional fluid-based approach.

This revolutionary system developed by ZF replaces the usage of brake fluid pressure with an electric motor, generating braking force at each wheel. The transmission of braking signals, from the pedal to the motor, operates exclusively within an electrical circuit. This innovative development, stemming from collaborative efforts across ZF’s laboratories in China, the United States, and Germany, was unveiled at the Next Generation Mobility Day in Shanghai, emphasizing software-defined vehicles (SDVs) and electric vehicles (EVs).

According to ZF, the brake-by-wire system not only reduces braking distances but also enhances energy recuperation during braking, thereby contributing to decreased maintenance expenses. In scenarios requiring automatic emergency braking, this system could potentially reduce the braking distance at 100 km/h by up to 9 meters when compared to conventional systems.

Particularly notable advantages are evident in electric vehicles, as the dry system facilitates more efficient recovery of braking energy during regenerative braking, potentially increasing the vehicle’s range by up to 17%. Importantly, ZF claims that drivers will not notice any discernible difference between the brake-by-wire system and the conventional hydraulic brake in terms of performance.

However, if you opt for the always-on display feature, the battery life reduces to about 3 days. While it may not match the endurance of certain other smartwatches like the Huawei Watch, it significantly surpasses many high-end models in this aspect.

In my experience, I’ve found that without using the always-on display, the Versa 4 easily stretches to a week on a full charge. Activating the always-on screen slightly diminishes this, bringing the battery life down to below three days. The usage of features like GPS can notably impact the battery life, draining it faster compared to continuous monitoring features like heart rate, which appear to be more power-efficient.

Fitbit includes a convenient fast charging feature that offers a quick boost to the battery. Just 12 minutes on the charging cradle can provide enough power for daytime tracking, akin to what was available in the Versa 3.

Verdict in Fitbit Versa 4 Review:

Despite the slightly reduced smartwatch capabilities compared to the Versa 3, the Fitbit Versa 4 remains a top contender as a fitness-tracking watch. It excels in monitoring daily activities and sleep patterns, and its focus on overall well-being and stress monitoring is commendable. Additionally, its user-friendly interface, customization options, and impressive battery life make it a strong choice.

However, for those seeking a more balanced array of sports, health, and smartwatch features, other options like the Apple Watch SE or Samsung Galaxy Watch might be worth considering, even though they may sacrifice a bit on battery life. The future trajectory of the Versa 4 as a smartwatch may also be affected, especially with the emergence of the Pixel Watch, which seems to receive more attention from Google and encompasses broader functionalities than Fitbit’s smartwatch lineup.
