What is SOC during VB energy transfer state?

The Δ SOC during VB energy transfer state is compared with the Δ SOC during VB blocked transfer state to clarify the Δ SOC changes caused by VB during the dynamic adjustment of the positive and negative bus voltages. In Fig. 3, Fig. 4, the effects of Psource and PL on Δ SOC show opposite changes.

How much does VB equalization reduce the change range of bus voltage?

When the SOCs of the two sets of BESUs reached equilibrium, the change range of positive or negative bus voltage in the control strategy proposed in this paper is reduced by about 4 V compared with the change range of the bus voltage based on VB equalization alone.

How does VB's blocked energy transferring state affect SoC?

In Fig. 3, Fig. 4, during VB's blocked energy transferring state, changes in loads and micro-source have a significant impact on Δ SOC, which the Δ SOC will decrease if PL decreases and Psource increases at Pnet < 0 or PL increases and Psource decreases at Pnet > 0, and vice versa.

What is a SoC balancing control strategy for energy storage units?

A SOC balancing control strategy for energy storage units with a voltage balance function is proposed. An analysis of SOC trends is carried out in response to the power changing of loads and micro-source. An adaptive virtual resistances algorithm is coordinated with the control strategy of VB to accelerate the balance process.

Are switched reluctance motors suitable for EV applications?

The potential of switched reluctance motors (SRMs) for EV applications is considerable. 26, 27 SRMs basically have two modes of operation. 28 If the velocity is lower than the baseline velocity the current may be limited by chopping, known as the current chopping control (CCC).

Why do electric motors need more energy management strategies?

Since the electric motor functions as the propulsion motor or generator, it is possible to achieve greater flexibility and performance of the system. It needs more advanced energy management strategies to enhance the energy efficiency of the system.
