• An electronic feature of a vehicle / aircraft / ship is patented to transmit the current battery level /
energy source status - also called SOC - for all external devices such as smartphones,
mobile navigation and / or tablet / portable PCs or notebooks via existing
Bluetooth / WiFi /
USB / NFC or other interface of the vehicle / aircraft / ship (* will be abbreviated as FFS below), to synchronize it and at defined intervals and / or permanently to calculate the optimal charging
route or charging stops on external devices mentioned above or for the apps / programs or all
software that can use this SOC
signal to calculate the charging points or charging
route of the FFS based on the current charge level of their battery or power source for example for
hybrid or
hydrogen vehicles. • All external devices and / or
software use manual methods to determine the current power source status of the vehicle / aircraft / ship, such as manually specifying the percentage or
state of charge, using a slider, or other "offline" and manually transferable methods to define it. This only occurs sporadically and does not take into account changes in the FFS* state, such as lighting, acceleration, or other electrical and electronic devices that can immediately affect the FFS's power source status and range, without the
software that calculates charging stops and charging routes noticing this without
delay and immediately updating the charging
route. • Constantly up-to-date information on the status of an FFS's power source enables a reliable and always optimal charging route for the vehicle / aircraft / ship, without manual intervention and readjustment of the latter by the driver or passengers, which poses an additional high risk for surrounding road users due to the high level of
distraction. Particularly in cases of sparse charging infrastructure, where there are not enough charging stations or facilities to meet
user needs, this invention proves to be a very useful and customer-
effective method for determining an optimal charging route and avoiding breakdowns and the subsequent additional effort and costs due to depleted energy sources and charging points that are not within available range.
