The power supply application requirements of lithium battery packs in medical equipment mainly include the following aspects:

Safety requirements: Lithium battery packs must comply with strict safety standards to prevent potential safety hazards such as leakage, short circuit or overheating. Lithium batteries should adopt an aluminum-plastic flexible packaging structure to reduce the risk of explosion. Even in extreme cases, the battery will only be limited to gas expansion rather than explosion. In addition, lithium battery packs must pass strict safety tests, including heavy object impact tests, thermal abuse tests, and overcharge protection, etc., to ensure the stability of the batteries under various conditions. Meanwhile, the battery management system (BMS) needs to be improved to monitor the battery status, prevent overcharging and overdischarging, and ensure safe use.

Performance requirements: The lithium battery pack should have a high energy density to meet the long-term use needs of medical equipment, and the battery size should be as small as possible to facilitate carrying and use. Meanwhile, lithium battery packs should have a long cycle life, reduce replacement frequency and lower maintenance costs. In addition, lithium battery packs should also have low internal resistance, support high-current discharge, and be suitable for devices that require instantaneous high power.

Environmental adaptability requirements: Medical equipment may need to operate in special environments, such as high temperature, low temperature, high humidity or high altitude conditions. Therefore, lithium battery packs should be able to operate stably at different environmental temperatures. Generally, medical lithium batteries can be used in a temperature range of -20℃ to 60℃, ensuring reliability in medical environments.

Customization requirements: Lithium battery packs can be customized according to the specific space requirements of medical devices, including shape, size and capacity, etc., to ensure the best integration. This customized design can meet the special power supply requirements of different medical devices.

Environmental protection requirements: Lithium battery packs should not contain harmful substances such as lead and mercury, and should not pose a threat to human health or the environment. During the production and use process, strict compliance with environmental protection regulations should be ensured to guarantee the environmental performance of the battery.

Compliance requirements: Lithium battery packs need to comply with international and national standards related to medical devices, such as the ISO 13485 quality management system, as well as the registration requirements for medical devices in specific countries (such as the FDA of the United States and the CE of the European Union). Meanwhile, it is also necessary to comply with the IEC 60601 series standards to ensure the electrical safety of the battery in the medical environment. In addition, lithium battery packs also need to pass transportation safety tests such as UN38.3 to ensure safety during transportation.
