The invention relates to a device for protecting a battery from electrostatic charging. In particular, the invention is directed to an electrically conductive covering for a vehicle battery having a plastic casing. The type of plastics typically used in casings for vehicle batteries have a tendency to develop electrostatic charges. The accumulation of such charges can result in flash overs that can damage the battery and, in certain circumstances, can result in explosions. The covering may be a film having a surface resistance of &#x3c;1&#xb7;10ohms that is connected to one of the terminals of the battery, thus draining the electrostatic charges that might otherwise build up. The covering may be provided with various features, including ribbing that preserves the structural integrity of the covering as well as different structures to hold down the covering on the battery. The covering is designed so that it can be customized to fit various battery types and sizes and is also reusable.

Device for protecting a battery from electrostatic charging

A process for improving the charge state of a motor vehicle battery arrangement having at least one battery and a generator driven by an internal combustion engine. Output power of the generator being at least partially utilized in order to charge the battery arrangement in the vehicle. The generator has an output voltage, which varies due to fluctuations in the speed of rotation of the internal combustion engine, and which is controlled so that it does not exceed a specific threshold value. Immediately after a starting process, at least under specific operating conditions, a raising of the specific threshold value U.sub.limit occurs during a specific period.

An electrochemical storage device comprises an electrolyte which forms an ignitable gas under certain conditions during use. The electrochemical storage device is constituted by a tank and a lid which is joined in a liquid-tight manner thereto and in which the terminal pillars are brought out at the top. Furthermore, it has a labyrinth-type pressure equalization connection built into the lid to connect to atmosphere the space situated above the electrolyte and enclosed by the housing. A separate, shape-adapted displacement body having an hermetically closed cavity is disposed in the space between the lid and the electrolyte surface so that the housing does not burst in the event of an ignition of the gas.
