Description
technical field [0001] The invention relates to the technical field of lithium battery systems, in particular to a lithium battery system and a working method. Background technique [0002] At present, the lithium battery system is only in the initial application stage in the field of industrial vehicles, and the electrical principle design is not perfect. The electrical principle design that has been verified and used in the field of electric vehicles can no longer be used on industrial vehicles due to cost and special vehicle use requirements: [0003] 1. Due to cost requirements and the communication connection with the vehicle strategy, the electrical design of industrial vehicles cancels the total negative relay; [0004] 2. Due to the cancellation of the total negative relay in the circuit, the principle design of charging heating and discharging heating needs to be made a new design; [0005] 3. The fast charging method used on new energy vehicles includes charging ...
