Core technology on the electric automobile is energy reserves and feed system, and the operation technique of resolving storage battery has just become the key problem in technology of electric motor car industrialized development.The present invention has finished the cell and the standardized designs of battery container in groups, and accumulators has been created an operational environment that safety is suitable, makes it give full play to usefulness, reaches safe handling and maintenance standard, has satisfied the instructions for use of electric automobile.

Summary of the invention

The design has realized standardization, seriation, generalization, satisfies the requirement of various electric automobiles to the power supply system standardized module.Rationally solved big case and little case, the Dialectic Relationship with in parallel, vehicle-mounted charge and separation of charged of connecting, and solved the local critical section that the ordinary appliances joint occurs.Have variable increase-volume, security monitoring, quick dispatch, ventilation constant temperature, waterproof, fire prevention, dustproof, do not have function such as exposed terminal, be suitable for the industrialized requirement of supporting charging of charging station and battery module retail quick change.

Embodiment

Now be described further in conjunction with the accompanying drawings.

Sub-cell and housing, end cap are combined into cell, and can select capacity as required is the combination of 100AH, 200AH or 400AH, sees Fig. 1-Fig. 7 for details.Select corresponding gland according to capacity, the gland both sides are to gather line telltale hole and fastener hole, and cell top connects with gland, the bottom connects with screw, have sealing three anti-functions, with jack and plug cell is assembled into single case battery pack according to capacity requirement then, see Fig. 8-Figure 11 for details.Battery bracket one end is the right angle fixed head, and the other end is removable location-plate, with carriage and the fastening location of battery pack, forms battery pack and bracket assembly with four long screw bars, sees Figure 12-Figure 13 for details.

Battery case is furnished with detection module, has temperature, voltage, capacity alarm indication, still has a cover to show with the instrument that case moves when separating with car body, makes the self-control thermostatic thermal element with special insulation material and Electric radiant Heating Film, and powerful centrifugal fan heat radiation also guarantees sealing.The casing front panel directly links together with battery pack, the assurance sealing of aliging with casing, and convenient disassembly, and the red handle of pulling on the panel can be pulled out battery pack.Be contained in the lead-out terminal on the bonnet, have sealing and positioning function, output has screw thread to be connected with the cable nose, and the wiring nose pierces into from pipe, is connected on the rear end cap lead-out terminal screw thread and with seal cover to seal.Casing top hollow toughened glass is incubated transparently, has more fail safe.The battery case left and right side respectively has two screw externally is installed, and two ventilation blowers are established in the centre, and air inlet is arranged at the bottom, sees Figure 15-19 for details.The battery case profile is seen Figure 20.

By the design of standardized battery case, can satisfy following requirement and condition:

1. satisfy the requirement of variable increase-volume

Different to the requirement of battery struck capacity and voltage level according to different vehicle, the design has taked cell gland connected structure, and connection in series-parallel is very convenient.Press 3.6 volts of calculating of lithium battery, the standard load that a single case of standard can be realized 100.8 volts-100 ampere-hours, 50.4 volts-200 ampere-hours or 25.2 volts-400 ampere-hours also can realize combination in any and reach the electric pressure standard.

2. satisfy the operational environment of battery

For guaranteeing battery operated environment, the design has been contained in battery in the automatic control ventilation insulating box, does heating element with Electric radiant Heating Film, adopts powerful centrifugal fan, and also can guarantee sealing property when ventilating.

3. satisfy security requirement

For guaranteeing security requirement, the design's cell shell and battery casing have in groups all adopted applied fireproofing, and explosion-proof drainage structure is set, and have designed waterproof and dustproof, the fire proof seal structure of not having any exposed terminal.

4. satisfy fast-assembling and quick-release requirement

For guaranteeing to decompose in groups and fast fast, monomer group has taked the gland connected structure, and FCL is connected in series fastening method with bolt in groups, and the little Battery pack of a plurality of monomers is fastened on the slideway supporting plate, put insulating box in identical with the drawer push-pull fashion, for the assembling and maintenance bring convenience.

5. satisfy the requirement of security monitoring.

Adopted single case with case self check, warning system, the dual battery management system of car load communication mode makes single case leave vehicle and also can pinpoint the problems.
