Battery Management System (BMS)
Overview
BMS(Battery Management Systems are designed for using with’s Zhongyi’s Scalable Lithium Battery. The BMS provides numerous system integration options facilitating temperature, voltage, current and state-of-charge monitoring. Scalable Battery Modules offer twice the run-time at nearly half the weight of similar sized lead-acid batteries, offering outstanding intrinsic safety, excellent float and cycle life resulting in low cost of ownership.
Features
- Monitor temperature, voltage, current, SOC, battery module error information
- One BMS can manage multiple battery modules
- CANbus or RS-485 communications for control and management
- Digital and analog I/O
- Battery-to-battery balance control
- Pre-discharge and pre-charge control
- Control of up to 4 contactors
- Insulation measurement
- Sleep mode when key signal ‘OFF’
