Description
TITLE: BATTERIES HOUSING
I. Background of the Invention 1. Field of the Invention The present invention relates in general to devices for heating batteries and, more particularly, to a batteries housing using hot or warm air for heating.
I. Background of the Invention 1. Field of the Invention The present invention relates in general to devices for heating batteries and, more particularly, to a batteries housing using hot or warm air for heating.
2. Description of the Prior Art The operation of a battery is conditioned by a number of factors, one of which is temperature.
Common batteries with aqueous or nonaqueous electrolytes perform poorly in environments colder than their lowest operational temperatures, because the electrolytes freeze and/or become viscous, with consequent degradation of ion-transport properties. Furthermore, for example, when an engine starts, the battery must produce high voltage energy and this becomes critical in cold weather when the resistance in the battery increases and the voltage is lower.
Conventional battery heating systems typically use a separate power source to supply energy to a heating element that generates the required heat. The resultant heat is then transferred to the battery by either a convection system or a conduction system. Convection systems blow hot air across the battery, whereas conduction systems apply heat directly to the surface of the battery.
Warm air heating requires complex mechanical systems that use substantial amount of external power. This constraint limits the portability of batteries and demands the availability of an external separate power source for heating the battery.
Systems employing thermal jackets usually include flexible insulators that wrap around of batteries. The thermal jackets must also be powered by separate power sources and require substantial amounts of energy.
II. Summary of the invention Accordingly, it is desirable to overcome the disadvantages associated with the prior art systems.
The present invention addresses these disadvantages by using a batteries housing comprising a structure having - two outwardly open compartments between which a hollow zone is interposed, each of the two outwardly open compartments being divided in several partitions, each of the several partitions being adaptable to receive one of several rechargeable batteries, the several rechargeable batteries having terminals for contacting a wiring;
each of the two outwardly open compartments being provided with -channels for air for heating the several rechargeable batteries, said channels for air for heating the several rechargeable batteries being located in the two outwardly open compartments, in and adjacent their walls, as follows: a) in a top and bottom walls and in a pair of second lateral walls, and open towards the several partitions, and b) adjacent a first lateral wall, for forming upper and lower passages.
In one aspect of this invention, use is made of inlet and outlet fittings affixed perpendicular to the first lateral wall, in an area corresponding to the hollow zone, and communicating with the upper and lower passages.
In another aspect of this invention, sizes of the several partitions and the several rechargeable batteries are so chosen that a light-press fit is obtained when the latter are inserted into the former.
III.
