Can hybrid energy storage system be used in battery electric vehicle?

The application of hybrid energy storage system with electrified continuously variable transmission in battery electric vehicle Model predictive control-based efficient energy recovery control strategy for regenerative braking system of hybrid electric bus

How much energy is recovered during the braking process?

It can be seen from Fig. 6 that during the whole braking process the total energy recovered by the compound energy storage system is 1.9 × 10 4 (J) and 1.17times of that recovered by the single battery system, which reflects the superiorities of the compound energy storage system and the proposed optimization method.

What are the advantages of braking energy recovery of electric vehicles?

The steady state errors and overshoots of the controlled system are significantly reduced. The load adaptability and anti-interference ability of the flywheel system are further improved. The above advantages provide theoretical and technical supports for the braking energy recovery of electric vehicles.

How does braking energy recovery affect battery life?

The efficiency of braking energy recovery, the speed control performance of FESS and battery life are increased. Braking energy recovery (BER) notably extends the range of electric vehicles (EVs), yet the high power it generates can diminish battery life.

Can a flywheel energy storage system improve battery life?

Braking energy recovery (BER) notably extends the range of electric vehicles (EVs), yet the high power it generates can diminish battery life. This paper proposes an optimization strategy for BER that employs a hybrid energy storage system (HESS), integrating a flywheel energy storage system (FESS) with a battery system.

What is the braking process of electric vehicle?

In the braking process of the electric vehicle, the braking energy is recovered and stored in the battery and flywheel devices, respectively. The main merit of the flywheel device lines in when the electric vehicle needs high power, it can convert mechanical energy into electric energy through the generator.
