Embodiment 1

[0066] In an electric vehicle, a specific large-capacity battery pack composed of multiple battery cells connected in series and parallel is used as a power source, and such a battery pack provides electric energy for the operation of the electric vehicle.

[0067] However, after the existing electric vehicles have been working for a period of time, there are problems such as unstable power output, abnormal operation of the electronic control system, and abnormal operation of auxiliary equipment (such as dimming of the light brightness) during driving.

[0068] The existing view is that the above situation is caused by the performance degradation of the battery pack after a period of operation and the unstable power supply caused by improper battery management strategies. Therefore, the current countermeasure is to replace the battery pack with better performance parameters and optimize the battery management software to provide a better battery management strategy. However, a...

Embodiment 2

[0083] This embodiment is further described on the basis of Embodiment 1.

[0084] In this embodiment, the hot-melt connection is formed by melting the two ends of the support column 130 after being heated.

[0085] The two ends of the support column 130 are heated and melted. Compared with the first fixing plate 110 and the second fixing plate 120, the processing process is simpler, the processing process is more controllable, and the range of heating and melting is smaller, which is conducive to maintaining the first fixed plate 110 and the second fixed plate 120. The structural strength of the first fixed plate 110 and the second fixed plate 120 .

[0086] There are many ways of hot-melt connection, for example, the two ends of the support column 130 are heated and melted and enter the holes or grooves provided on the first fixing plate 110 and the second fixing plate 120 to form an integral connection; the two ends of the support column 130 are heated After being melted, ...

Embodiment 3

[0100] This embodiment is further described on the basis of embodiment 1 or 2.

[0101] like figure 2 and Figure 5 As shown, the edge of the surface of the first fixing plate 110 away from the second fixing plate 120 protrudes upwards to enclose the first receiving groove 112, and the first fixing hole 111 is opened at the bottom of the first receiving groove 112;

[0102] The edge of the second fixing plate 120 away from the first fixing plate 110 protrudes upwards to enclose the second receiving groove 122 , and the second fixing hole 121 is defined at the bottom of the second receiving groove 122 .

[0103] The shape of the first receiving groove 112 and the second receiving groove 122 is the same as that of the current collecting plate, so as to accommodate the current collecting plate.

[0104] like figure 2 As shown, a plurality of first collector plate fixing holes 113 distributed among the first fixing holes 111 may also be provided at the bottom of the first rec...

Abstract

The invention discloses a battery pack support, wherein support columns are connected with a first fixing plate and a second fixing plate in a hot melting way not by bolts; by hot melting connection, the connection between the support columns and the first fixing plate and the second plate is more steady and firm, the relative moving between the first fixing plate and the second fixing plate, which is caused by bolt looseness, can be eradicated effectively, such problems as the power output is stable during th running process of a vehicle, an electronic control system works abnormally and accessory equipment works abnormally can be solved.
