Body;The battery unit is contacted by thermal grease with fin;The BMS circuit boards respectively with battery unit, humidity sensor
Device is electrically connected with;The battery unit, fin, BMS circuit boards, humidity sensor are placed in housing cavity.
It is preferred that the Li-ion batteries piles include two battery units, each battery unit include first support, second
Frame, battery;Battery is placed in by the first support with second support to be clamped between the two.
It is preferred that the fin cross section is T-shaped construction;The T-shaped horizontal end of fin is bonded with housing;Two electricity
Pool unit is located at the two sides at the T-shaped perpendicular end of fin respectively.
It is preferred that the first support, second support are that honeycomb is poroid;The thermal grease passes through second support honeycomb
Hole contacts with battery end, fin respectively.
It is preferred that the housing includes upper casing, shell, lower casing;The upper casing and lower casing are connected together with shell respectively.
It is preferred that the lower casing bottom sets the anti-reverse lead-out terminal being electrically connected with BMS circuit boards.
It is preferred that the Li-ion batteries piles also include a LED light on upper casing, itself and BMS circuit boards are electric
Property connection, for system intake early warning.
Using such scheme, the beneficial effects of the utility model are:
1) radiating effect is good:Take the poroid design of support honeycomb+thermal grease heat conduction to fin, fin by with
Shell Aluminum Drum, which fully contacts, carries out heat conduction outward;Particularly battery pack fast charge when, can be fast by high heat caused by heavy-current discharge
Speed exports to outside;The poroid design of honeycomb of support, effectively ensure the temperature consistency of each battery;
2) water inlet warning function:When internal battery pack is intake, humidity sensor will transmit a signal to BMS, system
Signal early warning can be carried out in Surface L ED indicator lamps;
3) it is anti-reverse:This battery pack connection terminal realizes that the rotation of 180 degree any direction is all unrestricted, prevents reversal connection from bringing
Battery failures even accident.
