What does KERS mean on Roewe cars?
3 Answers
KERS is the button on the Roewe ei5 that controls the intensity of braking energy recovery charging. The ei5's energy recovery mode is divided into three levels: light, medium, and high. These three modes differ in terms of recovery intensity and coasting distance. When the vehicle is braking or coasting, the braking torque drives the motor to work in a power generation state to charge the battery, thereby achieving energy recovery. KERS is the English abbreviation for Kinetic-Energy-Recovery-Systems. Its basic principle is to store the vehicle's braking energy through technical means and release it as auxiliary power during acceleration. The specific usage method may mimic the acceleration button of A1. The Roewe ei5 supports the energy recovery system. There are three adjustable stages. Drivers can select three levels of energy recovery—light, medium, and strong—via the KERS button on the gear shift knob. Different recovery levels and the suppression effect when releasing the throttle have noticeable differences. In terms of the Roewe ei5's braking performance, the braking effect of the power recovery system is significant. When stepping on the brake, the brake pedal remains linear with almost no dead space. Due to the low center of gravity, body nodding during braking is also well suppressed. The Roewe ei5 is equipped with a customizable energy recovery system. This model is a pure electric vehicle under the Roewe brand, officially launched in March 2021. It is a compact pure electric model with dimensions of 4600mm in length, 1818mm in width, 1543mm in height, and a wheelbase of 2665mm. The vehicle's motor has a total power of 135kW, a maximum torque of 280Nm, a full-charge range of 501km, a 0-100km/h acceleration time of 8.3 seconds, and an energy consumption of 13.3kWh per 100km. The fast charging time is 0.5 hours, and the slow charging time is 9.5 hours, making it a practical model with strong cost performance.
In Roewe vehicles, KERS is called the Kinetic Energy Recovery System, a nifty feature that saves fuel and is environmentally friendly. Every time you brake to slow down, the kinetic energy from the wheels isn't wasted; instead, it's captured by a generator and converted into electricity, which is stored in the battery for later use. The next time you accelerate or climb a hill, this stored energy kicks in to assist the engine, providing a power boost while also reducing fuel consumption and emissions. When driving the Roewe e550 hybrid, I noticed how smoothly this system operates—it feels effortless, almost like the car is secretly saving energy to help you cut costs. Over time, the maintenance expenses remain low, making it ideal for budget-conscious drivers like us.
Driving a Roewe with KERS feels incredibly satisfying. When decelerating, the system automatically recovers energy, as smooth as stepping on a soft cushion, instantly replenishing the battery. The next time you press the accelerator, the car responds much faster, especially in traffic jams or when switching on highways, with significantly less jerkiness, and the fuel consumption data looks much better. I believe this system makes daily commuting more worry-free, with simple operation that doesn't require manual switching, and the fuel-saving effect is noticeable. The money saved on fuel over a year is enough for one maintenance session. In terms of maintenance, just regularly check the battery status and ensure the wiring doesn't get damp or corroded. It's a practical feature well-suited for family cars.
