Regenerative Braking Control Of The Brushless Dc Motor

What is regenerative braking?

Regenerative braking is a common feature found on battery and hybrid electric vehicles. The idea of regenerative braking is that the existing system (motor/battery/inverter) works in tandem with the propulsion system to translate available kinetic energy into electrical energy that can be stored for later use .

Are regenerative braking systems effective in electric vehicles?

The efficacy of regenerative braking systems in electric vehicles is strongly correlated with operational conditions. In urban environments, which are characterized by dynamic driving and frequent acceleration and braking cycles, the kinetic energy recovery system can achieve high efficiency.

Are regenerative braking systems better than thermoelectric generators?

In addition, the work of Yu et al. indicates that RBSs attain the best fuel economy (4.08 %) compared to thermoelectric generators (1.67 %) and energy regenerative suspensions (0.9 %) in incorporating all three energy regeneration systems to formulate a single comprehensive energy system . 3.2. Enhanced emission reductions

Can Adaptive braking improve regenerative braking energy?

Elevated braking intensity correlates with an increase in regenerative braking force, which facilitates the system's ability to utilize a larger amount of regenerative braking energy. Scientific studies demonstrate that employing adaptive braking strategies can lead to a 15–25% improvement in recovered energy .

Can regenerative braking improve energy recovery?

Their simulations demonstrated that the proposed regenerative braking control strategy can enhance energy recovery up to 28.29 %. Similarly, Lyu et al. constructed a brake force distribution strategy amongst vehicle axles and developed an FLC to improve RB performance for a dual-shaft four-wheel-drive HEV.

What is a regenerative braking system (RBS)?

For instance, RBSs can include different forms of batteries (e.g., conventional lead-acid or Li-ion batteries) as their main ESS with a motor/generator unit (MGU) linked to them for electro-mechanical conversions. These systems fall under the electric regenerative braking (ERB) classification.
