What Are Some Common Uses of Integrated Series Batteries?

Integrated series batteries, also known as series-connected battery systems, are widely employed in applications that require higher voltage or enhanced energy capacity than a single battery can provide. These batteries combine multiple cells or modules in series, allowing the total voltage to equal the sum of each individual cell’s voltage. The resulting power output and flexibility make integrated series batteries suitable for a wide range of applications.

1. Electric Vehicles

Electric vehicles (EVs) are one of the primary users of integrated series batteries. These batteries are essential for providing the voltage and energy capacity necessary to power motors and extend driving range.

High Voltage Requirements: Electric vehicle motors require higher voltage to operate efficiently. By connecting battery cells in series, integrated series batteries can provide the necessary voltage to meet motor specifications. For instance, a system with 100 cells, each rated at 3.7 volts, can produce 370 volts, which is suitable for many EV applications.

Extended Driving Range: Series-connected batteries increase the overall energy storage of the system, allowing electric vehicles to travel longer distances on a single charge. This makes integrated series batteries particularly relevant for passenger cars, buses, and delivery vehicles, where consistent energy output is critical for operational reliability.

Flexible Configurations: Integrated series batteries can be combined with parallel connections to further increase capacity while maintaining voltage. This flexibility allows vehicle manufacturers to design battery packs that balance energy density, weight, and performance according to specific vehicle models.

2. Renewable Energy Storage

Renewable energy systems, such as solar or wind installations, rely on battery storage to manage energy supply and demand. Integrated series batteries provide a practical solution for storing electricity generated from intermittent sources.

Voltage Matching for Inverters: Renewable energy systems often require batteries to match the voltage input specifications of inverters and grid interfaces. By connecting cells in series, integrated series batteries can achieve the precise voltage needed to convert stored energy into usable electricity for homes or businesses.

Energy Capacity for Nighttime or Low-Generation Periods: Solar and wind power generation is not constant. Integrated series batteries store surplus energy produced during peak generation times and release it when demand exceeds supply, ensuring a consistent power source.

Scalability: Integrated series batteries can be scaled by adding more series-connected modules to increase voltage or combining parallel strings to expand capacity. This modularity allows renewable energy systems to adapt to varying energy requirements and available installation space.

3. Uninterruptible Power Supply (UPS) Systems

UPS systems protect critical electronics from power outages and voltage fluctuations. Integrated series batteries are commonly used to provide reliable backup power in these systems.

Consistent Voltage Supply: UPS systems require a stable voltage to protect sensitive equipment, such as servers, medical devices, or telecommunication infrastructure. Integrated series batteries can provide the required voltage while maintaining consistent energy output for a predetermined duration.

Extended Backup Time: Series connections allow the UPS to support longer discharge periods, offering sufficient time for equipment shutdown or transition to alternative power sources. This is essential in environments where even brief interruptions could cause data loss or operational disruptions.

Compact Integration: The modular design of series-connected batteries allows UPS manufacturers to fit large energy capacity systems into compact enclosures, optimizing space without compromising performance.

4. Industrial Equipment

Industrial applications often require high-voltage power sources for tools, machinery, and mobile equipment. Integrated series batteries provide reliable solutions for these environments.

Heavy Machinery and Electric Forklifts: Series-connected batteries deliver sufficient voltage and current to operate heavy machinery efficiently. For example, electric forklifts and material-handling equipment rely on these batteries to perform lifting and transport tasks consistently throughout the workday.

Automation and Robotics: Industrial robots and automated systems often require precise voltage control to ensure consistent performance. Integrated series batteries can supply steady voltage across the system, contributing to reliable operation and downtime.
