Abstract

The invention discloses a battery system integrated with different chemical systems, which comprises a first battery pack comprising a plurality of first battery cells connected in series and/or in parallel; the second battery pack comprises a plurality of second single batteries which are connected in series and/or in parallel; the first battery monomers and the second battery monomers are alternately arranged in the width or length direction of the module, and at least one large surface of each first battery monomer is attached to at least one large surface of each second battery monomer; the first battery state detection unit is connected with the first battery pack; the second battery state detection unit is connected with the second battery pack; the battery control unit is respectively connected with the whole vehicle control unit, the first battery state detection unit, the second battery state detection unit, the first battery pack and the second battery pack of the vehicle; and the first battery pack and the second battery pack are controlled to independently or jointly output power outwards according to battery parameters collected by the first battery state detection unit and the second battery state detection unit and an instruction of the whole vehicle control unit.

Description

technical field [0001] The invention relates to a battery system and a control method thereof, in particular to a battery system integrating different chemical systems and a control method thereof. Background technique [0002] In recent years, with the decrease of fossil energy and the increasingly serious environmental problems, people have paid more and more attention to the research and development of new energy vehicles. The rapid development of new energy vehicles has made power batteries gradually replace gasoline as a new power source for vehicles. [0003] In new energy vehicles, because lithium-ion batteries have higher energy density and power density than other types of batteries, lithium-ion batteries are currently the most widely used battery type for new energy vehicles. Among them, lithium-ion batteries are usually classified according to the type of positive electrode material, and can be divided into lithium iron phosphate batteries, ternary lithium batter...
