Factory Acceptance Commissioning (FAC) is a procedure carried out at the manufacturing facility or factory to ensure that a system or equipment meets the specified requirements before it is shipped to the installation site. During FAC, the system undergoes rigorous testing and inspection to verify its functionality, performance, quality, and compliance with applicable standards and specifications. The FAC process involves various stakeholders, including the manufacturer, the customer, and sometimes independent third-party inspectors. Successful completion of FAC ensures that the system is ready for shipment and installation at the designated site.

Frequency Containment Reserve (FCR) is a type of ancillary service provided by power systems to maintain grid frequency within predefined limits. FCR resources are capable of adjusting their output or consumption in response to frequency deviations from the nominal value. Unlike Fast Frequency Response (FFR), which responds to rapid frequency changes, FCR resources provide longer-term support to help restore grid frequency to its target level after significant disturbances or imbalances occur. FCR helps ensure grid stability, prevents cascading failures, and maintains the reliability of electrical power systems during various operating conditions.

Fast Frequency Response (FFR) refers to the capability of a power generation or demand-side resource to quickly adjust its output or consumption in response to fluctuations in grid frequency. Maintaining grid frequency within acceptable limits is crucial for the stability and reliability of electrical power systems. FFR resources, such as certain types of power plants, energy storage systems, or demand response programs, can rapidly increase or decrease their output to help balance supply and demand on the grid, especially during sudden changes or disturbances. FFR plays a vital role in supporting grid stability, managing frequency deviations, and ensuring the reliable operation of power systems.

The public electrical grid refers to the interconnected network of power generation, transmission, and distribution infrastructure that delivers electricity to consumers. Electric vehicle charging relies on the grid for power supply.

Grid Integration involves the seamless integration of electric vehicles and charging infrastructure with the electrical grid, optimizing energy use, managing demand, and supporting grid stability through smart charging and V2G technologies.

Heavy Duty Electric Vehicles are electric vehicles designed for transporting heavy loads or performing demanding tasks such as hauling goods or construction materials. HDEVs contribute to reducing emissions in sectors traditionally reliant on fossil fuels.

The International Electrotechnical Commission (IEC) is a global organization that develops and publishes international standards for all electrical, electronic, and related technologies. It sets standards for devices, systems, and services that use or produce electricity, including those in areas such as power generation, transmission, distribution, and utilization. The IEC’s standards help ensure compatibility, interoperability, safety, and efficiency in various electrical technologies across different countries and industries.

Kilowatt (kW) is a unit of power, while Kilowatt-hour (kWh) is a unit of energy. kW measures the rate of energy transfer or consumption, while kWh quantifies the total amount of energy consumed or stored over time.

Lithium FerroPhosphate (LFP) is a type of lithium-ion battery chemistry that is gaining popularity due to its safety, long cycle life, and stability. It is composed of lithium iron phosphate as the cathode material, which offers improved thermal and chemical stability compared to other lithium-ion battery chemistries. LFP batteries are known for their high energy density, fast charging capabilities, and resistance to thermal runaway, making them suitable for various applications, including electric vehicles, renewable energy storage, and portable electronics.

Site Acceptance Test (SAT) is a crucial phase in the implementation of a system or equipment, especially in large-scale projects like construction, engineering, or technology deployments. The SAT is conducted at the site where the system will be operational, and it aims to verify that the system or equipment meets the specified requirements and functions correctly within the intended environment. The SAT typically involves testing various aspects such as functionality, performance, interoperability, and compliance with regulatory standards. Successful completion of the SAT indicates that the system is ready for operational use at the site.
