Product type
A Battery Management System (BMS) is an essential component in electric vehicles (EVs) and energy storage systems that monitors and manages the performance of battery packs. It ensures the safe operation of batteries by overseeing their charge and discharge cycles, balancing cell voltages, and protecting against overcharging, overheating, and deep discharging. Typically composed of hardware and software elements, a BMS uses sensors and control algorithms to maintain optimal battery health and longevity.
| Input voltage range | 48V to 800V |
| Communication protocols | CAN, RS-485, Modbus |
| Cell balancing method | Passive or active balancing |
| Temperature monitoring | Thermistor or digital temperature sensors |
| Protection features | Overvoltage, undervoltage, overcurrent, and thermal protection |
| Dimensions | Varies by application, typically compact designs |
When selecting a Battery Management System, consider the specific voltage and capacity requirements of your battery pack. It is important to specify the desired communication protocols for integration with other systems, as well as any necessary safety features such as thermal protection and cell balancing methods. Additionally, inquire about certifications and standards compliance relevant to your application, and determine the quantity needed for your project to ensure availability and cost-effectiveness.
