Description
Technical field
The utility model relates to a kind of Large Copacity new type lithium ion battery group.
Background technology
Battery pack has the battery core of multiple parallel connection, and common electrode, thus increase the capacity of battery, lug is used for conduction electrode and multiple battery core, therefore, if connect firm not, larger contact resistance is easily caused, cause battery-heating serious, dangerous increase, in addition, connects the loose contact also easily causing battery core and electrode built on the sand, and, when lug is connected with multiple battery core, if adopt welding, can cause changing battery core inconvenient, therefore, be necessary to design a kind of novel Large Copacity new type lithium ion battery group.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of Large Copacity new type lithium ion battery group, and this Large Copacity new type lithium ion battery group novel structure, is connected firmly, good stability.
The technical solution of utility model is as follows:
A kind of Large Copacity new type lithium ion battery group, comprises base (8), battery core (5), drainage piece (4), lug (2) and electrode (1); Large Copacity new type lithium ion battery group also comprises through hole-bolt-nut mechanism;
The lower end of electrode (1) is connected with N number of lug (2), N be greater than 3 integer; Form one between 2 often adjacent lugs for holding the groove of drainage piece (4) upper end, described groove is N-1;
Drainage piece is N-1, the upper end correspondence of N-1 drainage piece to be inserted in a described N-1 groove and to be fixed by described through hole-bolt-nut mechanism, the upper end of drainage piece and lug are equipped with for the through hole through bolt (3), are fixedly connected with by screw bolt and nut (6) between the upper end of drainage piece and lug;
The lower end correspondence of N-1 drainage piece is connected with N-1 battery core (5); N-1 battery core is arranged in the base.
N is the integer between 4 ~ 6.
N is 4.
Through hole-bolt-nut mechanism is 2 covers.
The dividing plate (7) of polylith for separating adjacent battery core is provided with in described base.
Beneficial effect:
Large Copacity new type lithium ion battery group of the present utility model, adopt the multi-disc lug of fence type and 2 cover through hole-bolt-nut mechanisms to realize the connection of electrode and battery core, drainage piece is not easy to get loose, and electrical contact is good, and, owing to adopting bolt-nut fixed mechanism, it is all very convenient to mount and dismount, and is convenient to change battery core, therefore, this Large Copacity new type lithium ion battery group novel structure, is connected firmly, good stability.
