• Then, the thermostats, that will be placed on the cover side, have to be in direct
contact with the batteries. However, the role of the support, which is to prevent the
batteries' bulge, must not to be forgotten. This fact does not allow to increase the
height of the entire cover. So, some notches have to be manufacture in the cover to
allow the thermostats' integration. This step is illustrated in Figure 3.20.

• An important fact that must be noted is that the thickness of the batteries is not
constant. Indeed, there is a small part, including an electrical insulator, which is of
negligible thickness. So, to avoid any bulge of the thicker part, some end stops must
be added under the cover. This step is illustrated in Figure 3.21.

• Finally, as for the box, some weld toes are added to obtain the nal design of the
cover presented in Figure 3.22.
