| 16S–20S 90A Smart BMS for Energy Storage Systems Precision Control | Stable Output | All-Round Protection Designed specifically for residential and commercial energy storage systems (ESS), the 16S–20S 90A Smart BMS offers smart battery management, strong protection, and excellent dependability. It is perfect for uses requiring lithium battery packs with mid-to-high voltages, guaranteeing effective and safe power delivery throughout each cycle. Key Features: Wide Compatibility Offers versatility for a range of ESS designs and supports 16S to 20S lithium battery combinations. It is compatible with chemistries like LiFePO4 (LFP), NMC, and LTO. High Current Handling This BMS is ideal for medium-to-high power energy storage requirements in residences, telecom towers, solar systems, and industrial backup because it is rated for 90A continuous current. Full Safety Protection Suite • Protection against overcharge and overdischarge to preserve battery health • Protection against short circuits and overcurrents for increased system security • Temperature monitoring to guarantee low-temperature startup safety and avoid overheating • Cell balancing to keep voltage constant and prolong battery life Advanced Communication RS485 and CAN connections are included for easy interaction with remote monitoring platforms, EMS systems, and inverters. Smart Control For remote diagnostics, parameter change, and real-time data visualization, it integrates with PC monitoring software and an optional Bluetooth mobile application. Built-In Thermal Management Longer system lifespan is increased by the BMS’s effective thermal design, which uses aluminum heat-dissipation components to keep it cool during high-load operation. Typical Applications: • Residential and commercial solar ESS • Off-grid backup battery systems • Telecom base station power supply • Industrial UPS battery banks • Microgrid and hybrid energy systems Why Choose Us? 20+ Years of Industry Experience With over 20 years of experience in battery management and power solutions, we are the most qualified to comprehend the needs of the evolving electric vehicle and energy storage markets.

A: A smart Battery Management System (BMS) is responsible for keeping track of and reporting on the condition, functionality, and upkeep of the related battery. Data centers, hospitals, banks, telecommunications towers, energy storage stations, and more are just a few of the many locations where smart BMS are used. Q: What is the BMS for energy storage systems? A: It optimizes the battery’s performance and lifespan by keeping an eye on and controlling its operation to make sure it stays within safe bounds. For electric cars, renewable energy storage systems, and portable gadgets to function securely, dependably, and effectively, the BMS is essential. Q: What are the three types of BMS? A: In total, there are three common types of BMS architectures • Small, single-board BMS. • Distributed BMS. • Large, centralized BMS. Q: What is the difference between smart BMS and dumb BMS? A: Because dumb BMS is simple and dependable, it might be better suited for severe or distant locations. Integration and Communication: Determine if your application needs the ability to integrate and communicate. A Smart BMS is the best option if you require data exchange or remote monitoring. Q: What is the difference between smart BMS and standard BMS? A: Compared to a regular BMS, a smart or intelligent BMS provides additional monitoring and analytical capabilities and connects with the bicycle. The bike determines which battery is best. Does it have everything it needs to communicate with the battery? |
