What is Automotive CRBS?
3 Answers
Automotive CRBS is a braking system. Here is extended information about CRBS: 1. Braking energy recovery method: Currently, there are two ways to achieve motor braking energy recovery in vehicles - one is called Parallel Regenerative Braking System (RBS), and the other is called Serial Regenerative Braking System (CRBS). 2. Impact on range: The CRBS system may consume more energy through motor reverse braking than it recovers during low-speed driving, which could negatively affect the vehicle's range. Most new energy vehicles are equipped with CRBS systems that can intelligently distribute the proportion of power recovery and mechanical braking when the driver applies the brakes.
CRBS stands for Cooperative Regenerative Braking System, which is primarily used in hybrid and electric vehicles. Simply put, when you press the brake pedal, the system converts the kinetic energy that would otherwise be wasted into electrical energy and stores it back in the battery. Traditional car braking relies on friction to generate heat, dissipating all the energy into the air, but CRBS allows the electric motor to act as a generator, charging the battery while braking. I find this system particularly clever—it works seamlessly with mechanical brakes. Light braking mainly relies on energy recovery, while traditional calipers engage during heavy braking, ensuring both energy savings and safety. The most noticeable benefit is an approximately 15% increase in range. When driving, I can feel that the brake pedal travel becomes slightly longer, but the braking effect is more linear.
I love the CRBS feature the most when commuting with my hybrid every day! Every time I slow down on a downhill or before a red light, the dashboard shows a green arrow indicating charging. The biggest difference from regular braking is that when CRBS is working, there's almost no noise, and the brake pads don't get hot. Once after driving on a mountain road, I specifically touched the wheel hub, and the temperature was much lower than my colleague's fuel-powered car. This system is particularly useful for extending the life of brake pads. When I went for maintenance after driving 30,000 kilometers, the mechanic said the brake pads were less than half worn. However, it takes some getting used to at first because there's a slight dragging sensation when releasing the accelerator, but once you get used to it, you'll find the one-pedal mode super convenient.
