Abstract

An insulating jacket for a vehicle battery, which acts to maintain the battery temperature and therefore operating efficiency in cold weather. The jacket is made from a foldable sheet material so that it can be stored in a flat condition. <IMAGE>

Description

vehicle Battery Protection Device" This invention relates to a device for protecting a vehicles batteries from the effects of low temperatures, and in particular to a device which provides heat insulation, so as to enable the battery to retain heat generated during normal use, or by means of an auxiliary heating device.
Most vehicle batteries are designed to operate at optimum efficiency at 250C. For every one degree fall in temperature there is one percent loss of power below 250C, therefore at 00C loss of power is 25%.
Accordingly, the present invention provides a collapsible heat insulating jacket, which is adapted to be positioned around a vehicle battery. Preferably the jacket and includes a flap like cover member having releasable fastening means.
Preferably the jacket is so constructed that it can be folded flat, and is made from a material which is both fire and acid resistant, and the flap like cover is so arranged as to enable access to the top of the battery, for servicing purposes.
The jacket material may be elasticated, so as to ensure that it fits snugly around the battery, and can be used with batteries in a range of similar sizes.
The jacket may for example be constructed of an outer 1skin" of plastics material with an insulating material, or may alternatively be integrally moulded from a foamed plastics material.
In the winter when most batteries in vehicles are fairly low on charge anyway (due to greater use of headlights and heaters) the power saving which the insulating jacket can achieve would make the difference between being able to start a vehicle and not being able to.
In use the battery accumulates heat from the small amount generated by the charging process, by its contact with the hot air produced by the engine, and by heat caused by radiation of sunlight upon the vehicle.
Additionally, the jacket may incorporate a resistive heating element, and may be provided with control means which is adapted to supply current to the element, under certain circumstances. For example, the arrangement may be such that current is supplied to the element, whenever the vehicle engine is running and thus the alternator is generating a charge, or when the ambient charge temperature is below a certain level, or under a combination of these circumstances.
Further the heating element may be made of a material which has a "positive temperature coefficient so that less current is consumed, as the temperature increases.
Some embodiments of the invention will now be described by way of example, with reference to the accompanying drawings, in which: Figure 1 is a schematic perspective view of a jacket in accordance with the invention, in an installed and partially open position; and Figure 2 is a plan view of the jacket of Figure 1 with the cover open; Figure 3 shows a plan view of a sheet of fabric for making a first type of jacket in accordance with the invention; Figure 4 shows the jacket of Figure 3 in partly made-up form; Figure 5 shows a perspective view of the jacket of Figure 3 in a further stage of assembly; Figure 6a shows a perspective view of the finished jacket of Figure 3 in use; Figure 6b shows a base for use with the jacket of Figure 6a; Figure 7 shows a plan view of a second type of jacket, in unfolded form; and Figure 8 shows the jacket of Figure 7 in use in its made up form.
Referring to Figures 1 and 2, which shows the general form of the jacket of the invention, the jacket 2 is generally box shaped, although the underside, not visible in the drawings, is open so that the cover can be positioned over a battery 6, whilst it is installed in the engine compartment of a vehicle, without the necessity for removing the battery from its normal position.
A closable flap 14 is preferably integrally formed with the jacket, and connected to it along one edge 16, so that in use, the jacket can be positioned over the battery, as shown in the drawings, and the flap then closed over the top of the battery. In order to secure it in position, the flap 14 is made somewhat wider than the battery and a row of stud fasteners of well known construction are arranged along the free edge of the flap with their cooperating parts arranged along the corresponding edge of the corresponding side of the jacket 2. Of course, any other suitable form of easily releasable fastener may be used.
The jacket may be constructed in various ways, of which two preferred ones will be described in more detail.
The first construction is illustrated by Figures 3 to 6, in which the jacket consists of a sandwich of a synthetic plastic sheet material 20 on the outside and an insulating material on the inside. The cover of the jacket can be made from plasticised P.V.C, polyurethane, or polyethylene, bonded onto a knitted fabric in order to increase tear resistance.
The material may include additives to improve fire retardant and acid resistant qualities. Tests using a fire retardant polyurethane bonded onto a fire retardant knitted fabric have proved favourable.
The filling 8 of the jacket (Figure 5) may for example comprise glass fibre or mineral wool. Both have equally suitable qualities. The seams of the jacket can be sewn or welded, depending on the nature of the plastic cover.
The cover can be made from a single piece of material as shown in Figure 3, which is folded in half and sewn to form the jacket of Figure 4.
The jacket is then "wrapped~ around the battery and secured at a corner using either press studs 18 or hooks and eyes. The advantage in using this method, rather than a "joined-up box" is that the jacket can be fitted or removed from a battery without disconnecting the leads from the battery terminals. It also means that the jacket can be packed flat for storage or sales.
The lid-flap 14 which covers the top of the battery is held down using either press studs or a velcro" strips 24 (RTM).
Since it is not possible to make one size that fits all vehicles because of the wide range of battery sizes available, the jacket can be made in a range of sizes. The thickness of the insulating material (and hence of the side walls of the jacket) will of course depend upon the amount of space available in the vehicle. Thus a range of wall thickness may also be made. Tests with a wall thickness of approx. 2" have provided 50% heat saving over an uninsulated battery.
The jacket of the invention is quite efficient without any base at all. However, a separate insulated base (26) may be provided for the underside of the battery.
Tests indicate that a further 15% of heat may be saved by this method. The base must have all the water, acid and fire resistant qualities of the cover, and in addition be rigid and flat, so that the battery will not rock. The base may be constructed of cork covered with polyurethane or a completely synthetic material.
An alternative construction is illustrated in Figures 7 and 8 in which a one piece moulding 30, Figure 7 in the flattened shape of the jacket is made from selfskinning polyurethane foam, which is cast under foam pressure. The surface skin has all the necessary qualities of water, battery acid, oil and grease resistances plus fire retardant qualities. The interior structure of the material comprises a cellular foam, with increasing sized cells towards the centre of the casting. This provides the necessary insulating qualities.
The moulding is then folded into a box shape (Figure 8) with side walls which are up to 50mm thick, although technically up to 150mm is possible. The flap (not shown) acts as the lid to enable battery servicing is integrally moulded along with the box. Only the lid and side fasteners need to be attached after the moulding process. Being flexible the jacket can be sold in the folded flat form.
A base for the box can be optionally provided made from the same material, or out of more rigid synthetics, and does not have to be joined to the box.
Due to the moulding process, a flatter, squarer box can be made by this method, which ensures more evenly distributed insulation, than using the filled jacket method of Figures 3 to 6.
Embedded within the insulation material, there may be a series of heating wires which are connected into the electrical circuit of the vehicle, by means of a suitable control circuit (not shown). This may be arranged (for example) so as to supply additional heat to the battery, as soon as the engine has been started in cold weather, so that its temperature is rapidly raised to a level at which it achieves good efficiency (i.e. at least 200C) even if the engine is only operated for a short period. Thus, even if the vehicle is only driven for a short distance, the battery will be quickly restored to a fully charged condition at which it achieves maximum efficiency, and also, as a consequence of the high average density of the material making up the battery, combined with the insulating qualities of the jacket 2, a considerable amount of heat will be retained, so as to ensure that the battery works at the best possible efficiency the next time the vehicle is started.
It will be appreciated that the exact shape of the jacket is not an essential feature of the invention, but either of the types of jacket described with reference to Figures 3 - 6 or Figures 7 and 8 may be made in any shape suitable for the application.
