Conversion efficiency of each part of the energy storage container

How to validate the design of energy storage converter?

To validate the design, the experimental prototype is developed to verify that the proposed energy storage converter exhibits exceptional efficiency and reliability.

How to reduce the energy consumption of a reefer container?

For example, reducing the idle in operations, energy-aware scheduling of equipment, slight postponement of duty cycles, reduction of simultaneous lifting, and limiting maximum energy use can also bring energy cost reductions. Similar to the equipment, a significant portion of the energy consumption comes from reefer containers in some ports.

What is the difference between conversion efficiency and total efficiency?

Towards full load, the difference between conversion and total efficiency decreases and at full utilization, conversion efficiency is 85%, and thus only 4 percentage points lower. The relative losses, again over the charge-based utilization grouped into battery, power electronics, and system consumption, are shown in Fig. 11 c.

What is the difference between conversion losses and auxiliary power consumption?

The conversion losses are related to the conversion and storage of energy in the power electronics and battery respectively, whereas the auxiliary power consumption is the additionally necessary power for the operation of the system, namely thermal management as well as the control and monitoring components.

What is conversion efficiency optimum?

For higher utilization, conversion efficiencies increase to a peak value of 87% at 41% charge-based utilization (marked as conversion efficiency optimum) and decreases slightly afterward. Total efficiency is slightly lower, peaking at 81% at full utilization (marked as total efficiency optimum).

How does refrigerated container dwell time affect energy consumption?

The energy consumption and thus emissions for the cooling operations are time-dependent and strongly correlate with the refrigerated container dwell time in the terminal (Wilmsmeier & Spengler, 2016).
