Abstract

The utility model provides a storage battery charging is overheated to prevent short -circuiting device which constitutes and includes: temperature detect switch, safeties will the electrode of temperature detect switch, safeties and battery one end establish ties, temperature detect switch safeties battery, charger constitution series -wound loop, temperature detect switch sets up the position near holding battery electrodes. The beneficial effects are that: the utility model discloses the structure is fairly simple, and temperature detect switch and safeties low price realize the protection on the basis of costneutrality moreover.

Description

The overheated short-circuit preventing device of a kind of charge in batteries

Technical field

The utility model relates to a kind of storage battery protective device for preventing overheat, particularly relates to the overheated short-circuit preventing device of a kind of charge in batteries.

Background technology

Now there is a large amount of electric motor cars socially, because of battery circuit safety position arrange improper, frequently short circuit and fire hazard is caused in charging process, because charge in batteries needs 4-8 hours, in the process, personnel are substantially own falls asleep, unattended, also be difficult to disconnected battery supply, put out, and cause large area fire and casualties.

The fire that existing most of electric motor car charging short circuit causes, often because of its charging later stage, energy is sufficient, and temperature excursion, dissolves lead wire insulation rapidly, cause short circuit, in battery, all energy discharges rapidly initiation detonation, even if when there being people, is also difficult to power-off fire extinguishing, thus cause fire spread, cause heavy losses.

Due to the storage battery in battery case, in an enclosure space, in charging process, it is overheated easily to produce, and particularly some old storage batterys, after overheated, reach uniform temperature and also easily cause storage battery to catch fire, gently then property loss, heavy then threat to life.

Good technology can not prevent this phenomenon now, has some charge in batteries with protective device, but these device more complicated, and also protected effect is general.

Summary of the invention

The deficiency that the utility model exists for above-mentioned prior art, provides a kind of charge in batteries overheated short-circuit preventing device.

The technical scheme that the utility model solves the problems of the technologies described above is as follows: the overheated short-circuit preventing device of a kind of charge in batteries, its composition comprises: temperature detect switch (TDS), safeties, described temperature detect switch (TDS), safeties are connected with the electrode of storage battery one end, the series loop of described temperature detect switch (TDS), described safeties, described storage battery, charger composition, the setting position of described temperature detect switch (TDS) is near the electrode of storage battery.

Further, in the circuit that multiple storage battery is connected, described temperature detect switch (TDS) and described safeties all will have one.

Further, described safeties are Fuse Type insurance.

The beneficial effects of the utility model are:

1. the utility model have employed temperature detect switch (TDS) and is connected with storage battery with safeties, and these two apparatus cost are cheap, and technology maturation, facilitates large-scale application; And adopting temperature detect switch (TDS) and safeties simultaneously, safety effect is better.

2. in battery pack, each storage battery is connected, temperature detect switch (TDS) and safeties, like this when charging, if one of them has problem just can stop the charging of this storage battery at once, after temperature reduces, can recover charging automatically.

3., in battery pack, the operating temperature of each temperature detect switch (TDS) can set, and provides against any misfortune.

Accompanying drawing explanation

Accompanying drawing 1 is the schematic diagram of the single storage battery of the utility model.

Accompanying drawing 2 is the structural representation of the utility model battery pack.

Embodiment

Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.

As depicted in figs. 1 and 2, temperature detect switch (TDS) 3, safeties 2, storage battery 4, charger l form series loop, temperature detect switch (TDS) 3 and safeties 2 are arranged on charging circuit, the position that temperature detect switch (TDS) 3 is installed, as far as possible near the electrode of storage battery 4, if storage battery 4 occurs overheated, reaches the operating temperature of temperature detect switch (TDS) 3, temperature detect switch (TDS) 3 disconnects, charging process is closed, and when storage battery 4 temperature drops to below the operating temperature of temperature detect switch (TDS) 3, temperature detect switch (TDS) 3 is connected.

In electric motor car, the battery pack be made up of storage battery 4, in battery pack, have one group of temperature detect switch (TDS) 3 and safeties 2 at least, or on the output electrode circuit of each storage battery 4, temperature detect switch (TDS) 3 and safeties 2 are all set, play the effect of multiple security, in this multiple temperature detect switch (TDS) 3, the temperature that each temperature detect switch (TDS) 3 sets can be different, also can be identical, if it is overheated that one of them storage battery 4 occurs, reach this storage battery 4 nearest temperature detect switch (TDS) 3 operating temperature, so this temperature detect switch (TDS) 3 will disconnect the charging circuit of this storage battery 4.

Safeties 2 are Fuse Type insurance, and when these safeties 2 are set to and are connected in series to loop, setting is detachable, is convenient for changing safeties, in the line electric current or voltage excessive time, safeties 2 disconnect automatically, avoid causing battery pack to damage.

The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
