Abstract
The invention discloses a high-safety multifunctional power lithium battery pack. The high-safety multifunctional power lithium battery pack comprises a lithium battery module formed by a plurality of power lithium battery units connected in series, wherein each power lithium battery unit comprises a positive electrode battery box, a negative electrode battery box, and a plurality of parallel cylindrical cells, positive electrode parallel current converging boards and negative electrode parallel current converging boards, wherein the cylindrical cells are arranged between the positive electrode battery box and the negative electrode battery box; the positive electrode parallel current converging boards are arranged below the positive electrode battery box; the negative electrode parallel current converging boards are arranged below the negative electrode battery box; every two power lithium battery units enable the positive electrode parallel current converging boards and the negative electrode parallel current converging boards to be connected in series through busbars; and the lithium battery module is connected with a temperature control apparatus. By adoption of the high-safety multifunctional power lithium battery pack, the problem of insufficient coping to thermal runaway expansion in the prior art and the problem that the cells cannot be charged and discharged as normal in an extreme environment can be solved.
Description
technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a highly safe and multifunctional power lithium battery pack. Background technique [0002] Most of the existing power lithium battery systems use multiple batteries connected in parallel to form modules, and multi-level modules connected in series to form battery groups. The batteries currently on the market are mainly lithium iron phosphate batteries and ternary lithium batteries. The installation space of the power battery is restricted by the vehicle, while the ternary lithium battery has high energy density and good cycle performance, which can better meet the requirements of electric vehicles for the cruising range. In the small car and passenger car market, the application of ternary lithium batteries is becoming more and more extensive. [0003] However, as ternary lithium batteries are used more and more widely, corresponding problems are constantly exposed. ...
