Description
technical field [0001] The invention belongs to the field of lithium battery design and production, and in particular relates to a battery system parallel high-voltage control box. Background technique [0002] Lithium-ion battery is a new type of battery product that has developed rapidly recently. The product is green and environmentally friendly and belongs to new energy products. However, there are potential safety hazards in the lithium battery itself. Overcharging of the lithium battery will cause the lithium battery to burn and explode, causing major personal injury and financial loss; over-discharging of the lithium battery will reduce the service life of the lithium battery. [0003] When lithium-ion batteries are used in high-voltage systems in parallel, how to effectively control the charging and discharging of batteries is particularly important. The existing technology cannot realize the parallel control of multiple high-voltage lithium battery systems, nor can...
