Things to consider when choosing lithium batteries for system integration
Capacity
Capacity is an important variable when assessing the system compatibility of lithium batteries. Capacity, measured in ampere-hours (Ah) or watt-hours (Wh), determines the energy a battery can store and supply. For engineering and IT infrastructures, it is necessary to match the battery capacity to the system’s power requirements. Overestimating capacity can lead to unnecessary expenditure, while underestimating capacity can lead to power shortages.
Service life
The service life of lithium batteries is another important performance indicator. It is usually measured in terms of the number of charge and discharge cycles, i.e., the number of times a battery can be fully charged and discharged before its performance significantly deteriorates. For system integrators, the longer the service life, the lower the maintenance and replacement costs. Factors such as depth of discharge (DoD), operating temperature, and charging price affect the battery’s service life.
Requirements
When selecting a lithium-ion battery for system integration, it is first essential to understand your specific requirements. This includes examining the requirements of both the engineering and IT facilities, including power requirements, cargo, and ecological issues. For example, data facilities may have different power requirements compared to telecommunications configurations.
Performance indicators
Examining the performance of a lithium-ion battery involves analyzing capacity, lifespan and efficiency. Capacity is measured in ampere-hours (Ah) and indicates the amount of charge that can be stored in the battery. Lifespan is the number of charge and discharge cycles the battery can undergo before performance significantly decreases.
Efficiency is the ratio of output power to input power and is usually expressed as a percentage.
Safety features of lithium batteries
Battery management system (BMS): The BMS checks the status of the battery and ensures optimal efficiency and safety by balancing costs, controlling temperature levels, and preventing over- and under-voltage.
Thermal management: An effective thermal management system is essential to prevent overheating, which can lead to thermal runaway. Sophisticated cooling strategies and products help maintain safe operating temperature levels.
Overcharge and over-discharge protection: These functions prevent the battery from being charged or discharged beyond safe limits, extending battery life and preventing damage.
Short circuit protection: This function automatically disconnects the battery during a short circuit, preventing fires or surges.

Lithium-ion batteries in integrated systems Individual options
Customized dimensions
One of the main factors for system integrators to consider is the physical dimensions of the lithium-ion battery. Space is at a premium in many applications, and the battery must fit within specific dimensions. Customized battery dimensions can optimize space utilization and ensure the battery can be perfectly integrated into the system without compromising efficiency or safety. This modification is critical in medical tools, mobile electronic devices, and specialized industrial equipment applications.
Modular design
Modular layout is another important aspect of custom lithium batteries. Modular technology allows for a more flexible battery arrangement that can be easily scaled up or down depending on the system’s power requirements. This is particularly beneficial in applications where power requirements change over time, or redundancy is required for reliability. The modular layout also simplifies maintenance and replacement, as dedicated modules can be replaced without disrupting the system.
Protective functions
Integrating advanced protection features is essential for risk-free and reliable operation of lithium batteries in integrated systems. These safety features include
- Overcharge protection
- Over-discharge protection
- Short-circuit protection
- Thermal management
These features help to avoid common battery problems such as overheating, overload and short-circuiting, which can lead to battery failure and even danger. By customizing the protection features, integrators can ensure that the battery meets the specific safety needs of their application.
