Patent attributes
An apparatus, system, and method are disclosed for assuring uninterruptible battery power for a typical electric motor vehicle powered by an array of series-connected member batteries. Such assurance results from a provision of an electrically-operated bypass switch configured to form a closed electrical bypass circuit path across a faulty first member battery upon activation, thus keeping the vehicle powered up. In one embodiment, the bypass switch is a double-pole multi-contact selector switch connected to each member battery and complimented by a pole-connect switch. For an atypical electric motor vehicle, such as with a multiple battery array parallel configuration, a backup battery may be provided and connected with the faulty battery array in series to displace the bypassed member battery, thus maintaining equal voltage outputs from the battery arrays.
