Do mobile Bess applications have communication interfaces?

This thesis project, carried out at Northvolt Systems, aims to analyze the existing and readily used communication interfaces for a specific set of mobile BESS applications. The analysis is performed by a literature review of typical mobile BESS applications with the identified corresponding communication interfaces.

What are the hardware components of a Bess system?

The hardware components of a BESS system comprise the physical infrastructure that enables the storage and discharge of electrical energy. Including: Individual batteries form the core of the BESS system, storing electrical energy through electrochemical reactions.

What is Bess & how does it work?

One key application is for load shifting on-site generation, charging the battery from surplus solar or wind energy and discharging it later in the day to reduce grid import. Moreover, BESS is often used for peak shaving – reducing power usage during peak demand times to lower energy costs.

What is a Bess energy management system?

A crucial component of the BESS operation is its Energy Management System (EMS), which intelligently controls the charging and discharging of the batteries. Wattstor’s unique Podium EMS, for example, allows for day-ahead forecasting of price, generation, load and battery state of charge.

How much power does a Bess have?

The system is built of two main blocks. The PCS building block, responsible for the main control of the mobile BESS. The nominal power rating of the PCS block is 225 kVA, with a maximum peak power in the peak shaving mode of 275 kW . The second block is the modular battery pack.

What applications can a mobile Bess support?

The project aims to perform a thorough analysis of the various communication interfaces applicable to the applications that a mobile BESS can help support, of which, some typical VMS applications are construction sites, festivals, and EV charging stations.
