High-voltage high-power storage battery protection system and monitoring method thereof

Abstract

The invention provides a high-voltage high-power storage battery protection system, which is characterized by comprising a battery management control module, and a temperature control module, a smoke detection control module, an upper management system and a plurality of fire extinguishing devices which are respectively connected with the battery management control module through a circuit, wherein an input end of the temperature control module is connected with a plurality of temperature sensing devices through a circuit; and an input end of the smoke detection control module is connected with a plurality of smoke detection device through a circuit. By performing multi-point temperature monitoring on the storage battery, the high-voltage high-power storage battery protection system takes mean temperature as charging management of charging reference and simultaneously solves the problems of over-temperature and fire breakout of the storage battery through the temperature detection and smoke detection control in the using process, and the fire extinguishing devices are also arranged to effectively inhibit and prevent fire spreading after the storage battery is on fire.

Description

technical field [0001] The invention relates to a storage battery protection device and a protection method thereof, in particular to a protection system and a monitoring method for a high-voltage and high-power storage battery resistor composed of several single storage batteries connected in series. Background technique [0002] At present, batteries, as an energy component, have been widely used in various fields such as production, life, service, and scientific research. With the advancement of technology and the improvement of production means, the storage battery has also developed from the initial single lead storage battery to a variety of storage battery series including nickel-cadmium storage batteries, nickel-hydrogen storage batteries, and lithium storage batteries. At present, due to the low voltage of various types of single batteries, generally in the range of 1.2-2 volts, and limited power, in order to meet the demand for high-voltage and high-power electrici...
