BESS: Jelec Battery Energy Storage System

In the transition to a decarbonized electric power system, variable renewable energy  (VRE) resources such as wind and solar photovoltaics play a vital role due to their availability, scalability, and affordability. However, the degree to which VRE resources can be successfully deployed to decarbonize the electric power system hinges on the future availability and cost of energy storage technologies.

Battery Energy Storage Systems help make better use of electricity system assets, including wind and solar farms, natural gas power plants, and transmission lines. They can defer or eliminate unnecessary invest ment in these capital-intensive assets.

Jelec’s Battery Energy Storage System (BESS) is a comprehensive and proven solution that includes battery units and battery management system software. This ensures maximum efficiency and safety for each customer.

The Jelec Battery Energy Storage System consists of, lithium-ion batteries, a Battery / Energy Management System, any necessary DC/DC, or DC/AC power conversion / charging Equipment, a filter to mitigate the level of harmonics, and a reliable Power Management System.

JEMS: Jelec Energy Management System

Battery Management System

Battery Management Systems (BMS) monitor and regulate the charging and discharge of batteries. The battery characteris tics that are monitored include voltages, temperature, capacity, state of charge (SoC), power consumption, remaining operat ing time, charging cycles, and some advanced indicators like State of health (SoH).
The task of battery management systems is to ensure the optimal and safe use of the battery. To avoid loading the batteries, BMS systems protect the batteries from deep discharge and over-voltage. The battery management system also provides a cell balancing function to ensure that different battery cells stay equal, keeping the system in peak performance condition at all times.

Automatic Power Management System

The Jelec Automated Power Management System (JAPMS) is a solution to optimize the number of generator sets in operation and increasing the average efficiency of each generator set. This is achieved by implementing a Load Dependent Starting and Stopping System (LDSS) that automatically turns on and off generator sets based upon specific load and duration criteria. When excess generator usage is eliminated, fuel consumption, running hours, and carbon footprint are all reduced, resulting in significant operating cost savings. Reduced engine hours also result in less rig downtime and significant savings on regular maintenance costs.
