Abstract
The utility model introduces a battery box for charging nickel-hydrogen battery for vehicles, consisting of a box body 1 and connectors on the box body. The utility model is characterized in that at least one end of the box body 1 is provided with door heads 3 screwed with the box body. Two copper screws 4 communicated with the battery electrodes are respectively arranged on the two door heads; a connector 6 is arranged on the copper screw 4. Therefore not only the possible loose contact appeared in a unit cell in using and charging can be prevented and avoided, but also the using and charging performance of rechargeable battery can be effectively improved.
Description
Technical field
The utility model relates to a kind of automobile-used Ni-MH battery charging and uses battery case, belongs to DC charging method or charging device and auxiliary class.
Background technology
Along with the growing tension of petroleum-based energy, the lifting day by day of price, along with the raising of modern humans's environmental protection consciousness, moped is also developed to the direction based on electric power by oil gas fuel.But present most of electric bicycles are normally used to be lead acid accumulator.This lead acid accumulator commonly used has three big defectives: the one, and plumbous all harmful to environment and human body; The 2nd, the lead accumulator capacity is big; Three are to use the life-span short, whenever fill once electricity and can only power 2～4 hours, always with the life-span only in 1～2 year, though occurred the even more ideal lithium battery of performance in the market,, still do not fit into moped at present and use because its price is higher.
In addition, to the using and studying of automobile-used Ni-MH battery, in use also there is following problem in it through the inventor: at first, discharge and recharge though Ni-MH battery can reach thousand times on theoretical useful life, but often very easily damage, greatly reduction of service life because of application maintenance is improper.Its main cause is: 1, and the charging interval is long, causes voltage to surpass 1.43V and hot, the damage of swelling; 2, because Ni-MH battery has memory characteristic, when not using up the stored electric energy and charge repeatedly again when (voltage is higher than 1.2V), not only cause charging not advance, and its capacitance is reduced greatly; 3, (voltage is near 0V) can cause damage under over-discharge state.Secondly, seriously overcharging when scalding and to blast.It three is because cell voltage is 1.2V, will carry out a plurality of series connection and use when using 24V, 36V, 48V; If adopt each unit contact connected mode to use, little because of using electric current as contact pressure greatly to 5～10A, when causing the loose contact state, during greater than 0.5 Ω, both can cause contact loss, and can produce hot electrode and the battery of burning out at contact resistance.And when adopting the connection sheet metal that element cell is welded into the battery pack use, in case the wherein aging or damage of a batteries, will make when resistive causes serial connection charge greatly in it because aging battery voltage drop increase, and other battery charge deficiencies, cause charging uneven, damage because of a batteries that the most at last whole battery group is scrapped.
Therefore, design a kind of more scientific and reasonable Ni-MH battery charging composite set.Being to keep and prolong automobile-used Ni-MH battery useful life, also is a kind of necessary ways that improve its service efficiency.
The utility model content:
The purpose of the present utility model: be intended to propose a kind of Ni-MH battery that prevents and in use or charging process, can effectively prevent and eliminate the battery case of bad contact condition between the cell cube.
This automobile-used Ni-MH battery charging battery case, by box body 1 and and the wiring connector be located on the box body form, it is characterized in that: at least one end of described box body 1 be provided with box body be spirally connected 3.Respectively be provided with on described two heads one with the copper screw bolt 4 of battery electrode conducting.
Described copper screw bolt 4 is provided with one and connects jack 5.
Described copper screw bolt 4 is provided with a lug plate 6.
This automobile-used Ni-MH battery charging battery case according to above technical scheme proposition, because being provided with at the two ends of box body can be by the fastening door head of screw thread, and the suitable bindiny mechanism that on the door head, is provided with, therefore both can prevent and eliminate use and charging process in loose contact may appear in the element cell 10, so can effectively improve the serviceability and the charging performance of rechargeable battery.
Description of drawings
Accompanying drawing 2 is for using the utility model structural representation that banana plug connects;
Accompanying drawing 3 is for using the utility model structural representation that weld tabs connects;
Accompanying drawing 4 is the assembly drawing of the combined battery box of application the utility model composition.
Among the figure 1, battery pipe box 2, connector 3, door 4, copper screw bolt 5, connect jack 6, brace 7, banana plug 8, flexibly connect line 9, box body
Embodiment
This automobile-used Ni-MH battery charging battery case as shown in the figure, it is a kind of inventive improvements to existing various battery charge boxes, this automobile-used Ni-MH battery charging with battery case by box body 1 and and the connector be located on the box body form, it is characterized in that: at least one end of described box body 1 be provided with box body be spirally connected 3.Respectively be provided with on described two heads one with the copper screw bolt 4 of battery electrode conducting.Described connector can adopt the form of copper screw bolt 4, also can take to be provided with on this screw rod a banana formula jack, in use matches with it with banana plug 7, allows it be connected with other battery pack or is connected with electrical appliance; In addition, also can on copper screw bolt 4, a slice brace 6 outside transmission of electric energy be set by the mode of welding or be spirally connected.
What Fig. 4 provided is the assembled battery box that utilization single battery pipe box 1 constitutes, and the confession that it is made up of a plurality of battery pipe boxes 1 and plastic box body 9 flexibly connects battery case, forms a power supply by flexibly connecting line 8 polyphones between its each battery pipe box 1.Owing to all take the threaded door in two ends 3 formation in each battery pipe box, can guarantee that therefore the battery in each battery pipe box 1 has the excellent contact state.
