Abstract
ABSTRACT OF THE DISCLOSURE
This battery heater allows every battery independent of position (i.e.automobile load accumulator) to be heated up without ant external power sourco, and to improve the starting power while external temperature is low.
The circuit is constructed in such a way that an internal temperature below 0° C in the battery is prevented for a long period of time, and that a regular internal temperature of ca. 15° C in the battery is accomplished in most cases. In case the battery heater is switched on for a longer period of time, and the battery voltage drops below 12 V the battery heater will shift down to a minimal current of ca. 8 mA which is discharging the battery rather insignificantly. The battery heater functions maintenance-free, without any mechanical switches, and is only activated by a starter voltage of ca 14 V, in order not to influence the storage of the filled battery.
The durability of lead accumulator is, when using the battery heater, prolonged due to the constant internal temperature, because at the same time the development of lead sulfate (Pb SO4) in too large crystals is prevented or delayed in most cases.
In an electronically heated automobile starter battery the same Ah starting power i accomplished as in a battery of a size ca. 25 % bigger. This way the battery size can be reduced, and the enviroment is being charged with less lead acid waste.

Claims (7)
1. Electronic voltage- and temperature-regulated battery heater composed of an electronic control on a soldering platine (9) and four power transistors (16) installed on an aluminium plate (17) which is serving as a cooling sheet, and which is heated up by the four power transistors through their current flow.
The voltage required is being gotten directly from the plus-pole (12) and the minus-Pole (13) of the battery to be heated through the two connecting wire (6) with attached connecting rings (7, 8). The complete circuit entity is welded acid-proof in a foil (10), and is suspended in the interior (14) of the battery (15). Thereby, providing a 12 V voltage at the battery electronics and an external battery temperature below 15 ° C, the electrolyte and the active mass in the battery are heated up electronically, voltage- and temperature-regulated.
The voltage required is being gotten directly from the plus-pole (12) and the minus-Pole (13) of the battery to be heated through the two connecting wire (6) with attached connecting rings (7, 8). The complete circuit entity is welded acid-proof in a foil (10), and is suspended in the interior (14) of the battery (15). Thereby, providing a 12 V voltage at the battery electronics and an external battery temperature below 15 ° C, the electrolyte and the active mass in the battery are heated up electronically, voltage- and temperature-regulated.
2. Electronic voltage- and temperature-regulated battery heater in accordance with patent claim 1, characterized by the fact that the electronic control for the four power transistors (16) consists of two different-working temperature-regulators, one battery voltage control unit, and one fuse circuit,
3. Electronic voltage- and temperature-regulated battery heater in accordance with patent claim 2, characterized by the fact that the fuse circuit blocks the temperature control circuits by providing a minus voltages (3), and that the built-in fuse is damaged at ca. 14 V and thereafter discontinues to block the temperature circuit.
4. Electronic voltage- and temperature-regulated battery heater in accordance with patent claim 1, characterized by the fact that, instead of the power transistors (16) which serve as a heater, one single power transistor with similar development of heat is installed, or that a heating foil, a heating wire or a peletier element are approched via a circuit transistor.
5. Electronic voltage- and temperature-regulated battery heater in accordance with patent claim 1, characterized by the fact that the aluminium plate (17) with the heating and control electronics supplied with a plastic cover are installed on the exterior of the battery or directly built into the battery case.
6. Electronis voltage- and temperature-regulated battery heater in accordance with patent claim 1, characterized by the fact that the entire control circuit, or parts of it, are combined for the battery heater in an integrated circuit (IC), and that hereby the production of battery heating electonics is simplified substantially.
7. Electronic voltage- and temperature-regulated battery heater in accordance with patent claim 1, characterized by the fact that by the electronically regulated battery heater the battery is heating up in such a way that, at an external temperature of ca. 0° C, it produces an internal temperature of ca. 15° C, and herewith possesses approximately the same Ah starting power as a battery of a size ca. 25 % bigger, and thereby requires a lower amount of lead and acid in the battery.
