ABSTRACT:
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 <1·109ohms 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.
