Description

A kind of battery pack assembly

Technical field

The utility model relates to technical field of new energy, in particular to a kind of battery pack assembly.

Background technique

Environmental protection, energy security overall situation under, with the support energetically of national policy, new-energy automobile is in recent years It quickly grows, new-energy automobile quantity is in the rapid increase stage.But new-energy automobile associated safety accident is constantly sent out in recent years It is raw, hinder the development of new-energy automobile.Really, the development of new-energy automobile not sail right before the wind, as one concerning arrive people The product of body safety, property safety, Environmental security need to go the safety for guaranteeing vehicle, more particularly to vehicle from multiple angles High-voltage safety.And battery pack assembly is as the core component of high-pressure system, other than going to guarantee its reliability from components angle, It also needs to go to design associated high voltage circuit from vehicle angle, it is ensured that the safety of vehicle high tension loop.Also, it is related to this The power supply capacity of battery pack assembly is also to be improved, in addition the related subsidy policy in current China, double integrator policy are more likely to The development of pure electric automobile.

At present.It is as follows for battery pack assembly external high pressure electrical connection major programme: 1 group of heavy-current discharge connector of design It is externally exported for high pressure, 1 group or multiple groups low discharging current connector (can without), 1 group of direct current charge charge connector (can without), 1 group of trickle charge charge connector (can without).Existing scheme mainly applies to forerunner or rear-guard scheme: being directed to main high current components (electric machine controller) in vehicle front side or rear side, high voltage component is not simultaneously present front and rear sides phenomenon；Or even if other high pressures Component and electric machine controller, also because components demand current is small (cable diameter minor loop is few), run through front and back not in the same side Formula, which installs cable craft, to be influenced less.And it is directed to 4 wheel driven scheme, above-mentioned technical proposal is then unfavorable for arrangement and site technique Installation: battery pack only 1 group of heavy-current discharge output, no matter output interface is mounted on which direction of battery pack, will necessarily be related to The installation of at least 1 group of high-current cable from front to back (or from back to front)；Will be related to following disadvantage: cable need to be from interior cabling (occupying interior space, be related to cable across Metal Sheets for Body-manufacturing, there are leak and electrical safety risk, cable are difficult to install) or (channel space, difficult to install in occupancy, and cable, which is easily interfered with battery pack upper cover, occurs electrical safety wind for channel cabling in chassis Danger) or chassis two sides cabling (battery pack space can be occupied, reduce electricity arrangement, is difficult to install)；It can be related to occupying empty Between, installation is inconvenient and safety issue.

And existing usually high electricity design scheme are as follows: battery pack assembly is arranged in below chassis, and Y-direction installation point is fixed on vehicle Left-right longeron position (battery pack cabinet need to be located at side rail inner)；X to guarantee front overhang, Rear secondary frame for vehicle safe distance；Z-direction Big face and chassis keep designed distance, and middle channel position protrusion is designed for battery pack interior distribution, protrusion below back seat For placing two layers of mould group.There are following both sides defects for this scheme: 1, electrically-charging equipment is not perfect, 2, continual mileage not Foot, 3, space layout it is less reasonable；From the point of view of vehicle angle, the competitiveness that continual mileage will directly promote vehicle core is improved. Undoubtedly, battery pack assembly plays certainty as vehicle power resources, how many pairs of continual mileages of electricity.
