ESM-48100A9 is an energy storage unit composed of lithium-ion batteries. It features better charge and discharge performance, longer service life, and less self-discharge loss than ordinary batteries. An ESM consists of electrochemical cells, an energy storage management unit (ESMU), power and signal terminals, and mechanical parts. It can be used as an independent 48 V unit, supports the mixed use of old and new batteries as well as lithium and lead-acid batteries, and can collaborate with third-party power systems.

• Parallel connection for power expansion: The maximum power (P) of N ESMs connected in parallel can reach 24 kW. For details
• Application in class B environments with direct ventilation: The ESM can be used in indoor environments where the ambient temperature and humidity are not controlled or outdoor environments (with simple shielding measures such as awnings) where the humidity can reach 100%.
• Support for third-party power systems: The ESM implements lithium battery self-management so that it can be used with third-party power systems.
• Mixed use: In a Huawei power system, lead-acid batteries can be directly connected in parallel.
• Maintenance-free: This feature reduces battery O&M costs and the frequency of site visits.
• Long service life: The service life of a lithium-ion battery is two or three times that of an ordinary lead-acid battery. The battery state of health (SOH) and state of charge (SOC) can be monitored online in real time, improving the reliability of site power backup.
