Abstract

The invention discloses a battery management system which comprises a first relay, a second relay, a fuse, a resistor, a diode, a first battery connecting end and a first charging power supply connecting end, wherein the first battery connecting end is connected with the first end of the fuse, the second end of the fuse is connected with the first end of the first relay, and the second end of thefirst relay is connected with the first charging power supply connecting end; after the second relay is connected with the resistor in series, one end is connected with the first end of the first relay, and the other end is connected with the second end of the first relay; the first end of the diode is connected with the first end of the first relay, and the second end of the diode is connected with the second end of the first relay. The invention also provides a battery management device. The size of the battery management system is effectively reduced, and the space utilization rate of the system is increased.

Description

technical field [0001] The invention belongs to the technical field of batteries, and in particular relates to a battery management system and device. The battery management system can be applied to an uninterruptible power supply (Uninterruptible Power Supply, UPS) or an energy storage system with high voltage and medium and small power, and has a low cost, occupies a small volume, and has a high space utilization rate. Background technique [0002] With the widespread application of new energy electric vehicles, the capacity, safety, health status and endurance of batteries have increasingly become the focus of attention. The battery management system (Battery Management System, BMS) is a system for monitoring and controlling the battery, commonly known as the battery nanny or battery steward. Battery life, monitor the status of the battery. The battery management system can feed back the collected battery information to the user in real time, and at the same time adjust...
