The invention discloses an explosion-proof
lithium battery power supply having two output types, and an operating method thereof. The explosion-proof
lithium battery power supply comprises a power supply body and an external
protection system, wherein the external
protection system is composed of an intrinsically safe type dangerous mixture concentration monitoring and power supply
protection system, and the power supply body comprises an explosion-proof power supply outer shell and an encapsulation module. The operating method comprises the steps that a battery module charges and discharges with the outside by means of a
discharge positive
electrode, a
discharge negative
electrode, a charge positive
electrode and a charge negative electrode, and a battery
management system and the intrinsically safe type dangerous mixture concentration monitoring and power supply protection
system control the on-off of a controllable switching unit inside the encapsulation module, thereby realizing different output types of the
lithium battery power supply. The explosion-proof
lithium battery power supply and the operating method thereof have the advantages that: by adopting the explosion-proof protection method combining encapsulation protection, intrinsic safe protection and explosion-proof protection, multiple
electrical protection mechanisms and a plurality of circuit isolation methods, restrictions on use of the
lithium ion battery power supply in dangerous regions such as ''0'' region are effectively eliminated, and the application range of the
lithium ion battery power supply is expanded.
