The effect of magnesium alloy power battery module holder manufactured by the present invention is far better than existing battery modules holder.
Existing battery modules holder generally uses aluminium alloy extrusions to make, and front end closure plate, rear end closure plate, a left side are made with aluminium alloy extrusions
Side shield and right-hand apron, left side baffle and right-hand apron are a monoblock baffles；To mitigate weight, proximate matter, proximate matter are used
Middle part be it is empty, therefore it is bad be spirally connected, by closure plate and baffle attaching at, all using welding, can not being torn open when holder
Need multiple artificial and complicated equipment that could complete when unloading, and welding；Its fixing threaded hole being mounted on battery case runs through
Whole closure plate height so that its fixing bolt is long, increases weight.
Product of the present invention has lot of advantages compared with existing aluminium alloy power battery module holder：
1. being made of magnesium alloy materials, 30% or so is just alleviated on material properties.
2. using portable structure, side board is made of shelves item, reduces materials'use amount, using fixing threaded hole
Seat, the length of such fixing bolt greatly shorten, and further reduce materials'use amount, and 10% left side is alleviated from material utilization amount
It is right.
3. using side buckle and support Snap-bar structure, battery can be made to be more firmly mounted, improve making for battery modules
Use the service life.
4. using bolt attaching, convenience simple for process is not necessarily to complicated production equipment, and production efficiency is high；And aluminum alloy battery
Module bracket, which needs to weld, can just install, and complex process, the infusion of financial resourcess such as required process equipment such as welding robot are big,
Low production efficiency.
5. since this product uses bolt attaching, such as individual battery cores to be broken and can be replaced with dismounting helix, holder can continue
It uses.And the holder of welding is used to need that holder destruction could be replaced, time-consuming and waste material.
Generally, the weight of the aluminum alloy battery module bracket of standard specification has 583g, and the magnesium alloy of standard specification is electric
The only 377g of the weight embodiment 1 of pond module bracket, the only 385g of embodiment 2, the only 397g of embodiment 3.
Electric vehicle typically now has 24 battery modules, and by this calculating, aluminium alloy post total weight has 13992
It is a, and magnesium alloy bracket is used, weight at most only has 9528g, and at least only 9048g, significantly reduces the whole of battery case
Body weight.
Electric vehicle is raising course continuation mileage and energy content ratio has the high-grade battery core of pursuit, but energy storage at present preferable three only
First lithium battery security performance is not but high, and price is also more expensive, can be substantially whole if its module and battery case are changed to magnesium alloy materials
Body improves the energy density ratio of battery pack, and such electric car enterprise can be used energy storage and be weaker than ternary lithium battery, but other performance is as pacified
The complete preferable ferric phosphate lithium cell of property, can be by percent 30 or more battery pack cost reduction, and can not increase overall weight, can be complete
Full up foot relevant policies requirement.
