Energy Storage Systems in Batteries (BESS): What Are They and How Do They Work?

According to data from the International Energy Agency, global storage capacity must increase sixfold before 2030 to meet climate goals. In this scenario, Battery Energy Storage Systems (BESS) are the key piece that will transform how companies manage their consumption and electricity savings.

At V2C, we believe that the future of mobility and energy lies in integrated smart solutions: electric vehicle chargers connected to our new Oasys storage systems, an advanced BESS line capable of balancing demand, storing excess renewable production, and significantly reducing the energy bills of companies and industrial facilities.

What is a Battery Energy Storage System (BESS) and why is it key for energy savings

A BESS (Battery Energy Storage System) is a technological installation capable of storing electricity in chemical form to release it when it is most needed. It is not just a battery: it is a combination of hardware and software designed to optimize energy use and stabilize the grid.

These systems are particularly important for companies looking to save electricity by reducing demand peaks, managing renewables, and ensuring supply during critical moments.

Key aspects:

• They allow energy to be stored when rates are lower.
• They reduce dependence on the traditional electrical system.
• They increase the efficiency of photovoltaic self-consumption.
• They optimize the operation of electric vehicle chargers.

BESS turn stored energy into a strategic tool: lower costs, more control, and advanced management of electrical demand.

How a BESS works

A BESS operates very similarly to a smart energy ecosystem: it stores energy when there is surplus or low demand and releases it when consumption increases.

Main components of a BESS:

• Batteries: Lithium-ion or flow, depending on capacity and usage requirements.
• BMS (Battery Management System): Controls temperature, charge, and discharge to ensure safe use.
• PCS (Power Conversion System): Converts energy between direct current (DC) and alternating current (AC).
• EMS (Energy Management System): Coordinates energy flow and prioritizes savings, supported by artificial intelligence.

Together, these elements allow energy to be managed predictively, ensuring efficiency and energy stability for any installation.

How industrial BESS differ from domestic systems

The difference mainly lies in capacity and energy management.

BESS systems for companies are designed to balance the internal grid and reduce power costs during peak hours, while domestic systems aim to take advantage of stored solar energy or power an electric vehicle charger at strategic moments.

In industrial environments:

• They can be integrated into microgrids or photovoltaic plants.
• They increase electrical resilience against outages or overloads.
• They allow compliance with net balance and energy certification requirements.

In both cases, their purpose is clear: reduce energy expenditure and move towards real energy autonomy.

Oasys: the intelligent BESS that transforms energy management for businesses

Oasys is the first BESS developed by V2C that combines state-of-the-art batteries, advanced software with artificial intelligence, and a modular, all-in-one, Plug & Play design, capable of optimizing the energy use of any industrial or business installation. Its 100 kWh storage capacity and 50 kW power allow for up to a 40% reduction in energy costs, ensuring autonomy and operational continuity even during supply outages.

This system analyzes consumption patterns, electricity market prices, and weather forecasts in real-time to automatically decide when to charge or release energy, maximizing electricity savings and the performance of the electric vehicle chargers integrated into the installation.

Main features of Oasys:

• Predictive Artificial Intelligence: creates personalized charging plans based on consumption, solar production, and hourly energy prices.
• Intelligent energy arbitrage: buys energy when it is cheaper and releases it during high-cost hours.
• Optimized solar management: connects up to 65 kWp of photovoltaic energy to maximize self-production.
• Automatic Peak Shaving: injects energy from the battery to reduce demand peaks and avoid penalties.
• Hybrid or isolated operation: operates connected to the electrical grid, with solar energy, or via generator, ensuring total flexibility.
• Scalability and ease of installation: allows connecting up to 10 Oasys modules in parallel and starting up in less than 48 hours.

Thanks to the V2C Cloud software, the entire system can be monitored and controlled remotely: production, consumption, and storage in real-time, with automatic notifications, detailed statistics, and local technical support.

In simple terms, Oasys is the natural evolution of energy storage: a system that thinks, predicts, and acts so that every kilowatt counts, helping companies to be more efficient, sustainable, and competitive.

Why integrate a BESS with your V2C chargers

The integration between BESS systems like Oasys and smart V2C chargers represents the next leap towards low-impact, high-performance electric mobility. Thanks to the connection with our management system, companies can:

• Coordinate vehicle charging with periods of lower energy costs.
• Prioritize the use of stored or solar energy.
• Decrease contracted power without compromising operability.
• Facilitate the installation of electric vehicle chargers within energy optimization plans.

In short, a BESS like Oasys connected with V2C chargers turns every charging point into an intelligent node that learns, optimizes, and acts autonomously to drive savings.

Benefits of the BESS system for companies

Adopting a BESS offers tangible advantages in the bottom line and sustainability of any organization.

Most notable advantages:

• Economic savings: Lower energy costs through dynamic management.
• Operational stability: Energy available even during network incidents.
• Certified sustainability: Reduction of emissions and responsible consumption.
• Scalability: Possibility to expand capacity according to consumption evolution.

Energy storage thus becomes the foundation on which to build an efficient, competitive, and future-ready business model.
