the base module is configured to communicate the charge level of the external battery module to the user or a person other than the user.
6 . The medical system of claim 5 , wherein the base module is configured to control distribution of electrical power received by the external battery module to charge the external battery module and output electrical power to the base module.
7 . The medical system of claim 1 , wherein the base module further comprises a base module output connector comprising two power connectors, two ground connectors, and a data connector arranged in a symmetrical arrangement that accommodates two opposite connection orientations of a mating output connector with the base module output connector.
8 . The medical system of claim 1 , further comprising: a percutaneous connection line that operatively couples the medical device to the base module.
9 . The medical system of claim 1 , wherein electrical power for powering operation of the medical device is transferred via transcutaneous power transmission.
10 . The medical system of claim 1 , wherein the data connector comprises a fiber optic connector.
11 . A method of supplying electrical power to a medical device worn by a user or implanted in the user, the method comprising:
transmitting electrical power from an external power source to a base module through a base module input connector of the base module, wherein the base module input connector comprises two power connectors, two ground connectors, and a data connector arranged in a symmetrical arrangement that accommodates two opposite connection orientations of a mating output connector with the base module input connector;
supplying electrical power to the medical device via the base module; and
controlling, by the base module, operation of the medical device.
12 . The method of claim 11 , wherein:
the base module comprises one or more base module battery cells; and
the method further comprises controlling, via the base module, distribution of electrical power received by the base module to simultaneously charge the one or more base module battery cells and output electrical power to the medical device.
13 . The method of claim 11 , further comprising transferring a connection signal over a connection cable from an external power source to the base module indicating connection of the external power source to the base module.
14 . The method of claim 13 , wherein:
the external power source comprises an external battery module;
the external battery module comprises an external battery module controller and one or more external battery module battery cells;
the method further comprises:
monitoring a charge level of the external battery module;
communicating the charge level of the external battery module to the base module; and
communicating the charge level of the external battery module to the user or a person other than the user.
15 . The method of claim 14 , further comprising implementing a charging sequence in which the base module is charged first via electrical power received by the external battery module and the external battery module is charged via the electrical power received by the external battery module after the base module is charged.
16 . The method of claim 15 , further comprising:
generating a base module temperature signal indicative of a temperature of the base module; and
controlling, via the base module, charging of the base module based on the base module temperature signal to prevent a charging induced exceedance of a predetermined base module temperature.
17 . The method of claim 15 , further comprising:
monitoring a charge level of the base module; and
communicating the charge level of the base module to the user or a person other than the user.
18 . The method of claim 17 , wherein communicating the charge level of the base module to the user or a person other than the user comprises wirelessly transmitting the charge level of the base module to an electronic device for communication to the user or a person other than the user.
