As the electrification of construction machinery has just started to take off in recent years, few studies in the current published literature evaluate the different kinds of energy consumption and battery capacity requirements of ECMs, and provide corresponding methods for battery capacity selection.
What is a battery capacity selection framework for electric construction machinery?
Present a battery capacity selection framework of electric construction machinery. Evaluates energy consumption and battery capacity for variable operating conditions. A battery capacity selection process that considers multiple interest claims. Energy consumption and battery capacity are sensitive to its operating conditions.
In the next step, the variable operating conditions and parameters related to battery capacity selection are mathematically described, and then the optimal set of solutions for battery capacity selection is determined by using a double-layer optimization method targeting procurement and operating costs.
Are construction machinery batteries a competitive advantage?
The commercial battery technology is still evolving rapidly. Construction machinery manufacturers must keep a close eye on advances in battery technology and update their ECM battery capacity versions in time to gain a competitive advantage. Some studies [ 39, 40] have evaluated batteries' energy density and price.
Choose a battery capacity (Ampere-Hour) that surpasses the minimum capacity computed using the above formula. Mixing different battery sizes or types in a system is generally not recommended due to variations in voltage, capacity, and charging/discharging characteristics.
What are the steps in battery capacity selection framework?
The battery capacity selection framework is shown in Fig. 1, and it includes the following three steps: Step 1 Determining the range of operating parameters. Step 2 Calculating the objective function and solution sets. Step 3 Battery parameter solution sets decision.
How to select battery capacity of ECM based on variable operating conditions?
This study presents a framework for battery capacity selection of ECM considering variable operating conditions and multiple interest claims, which consists of three steps: The first step is to determine the construction machinery's operating scenarios and other factors depended on the requirements.
