The utility model also provides a kind of battery modules, and above-described battery bus has been used to carry out electricity between battery
Connection.
The lug of battery is welded direct to after the through slot on battery bus is pierced by substrate, and it is close to improve energy
Degree, at the same can meet again high current by the needs of.
In another embodiment of the utility model, the connection between the substrate and the lug of battery includes Laser Welding
Connect with ultrasonic bonding at least one of.
After having used technical solution provided by the utility model, the area of passage of battery bus is increased, is improved
The high current handling capacity of bus-bar；The welding of lug and battery bus is more firm, and convenient for examining, reduces rosin joint
Possibility；Tubaeform opening is opened in through slot one end of battery bus simultaneously, and battery pole ear can be convenient from the opening
It is inserted into, the step of reducing the requirement to precision, simplify assembling.
