Automatic battery connection switching

A connection management unit, CMU, the CMU being electrically connectable to a plurality of energy storage units configurable to provide power to a vehicle including an exhaust, the CMU being configured to:

• determine a connection arrangement of two or more energy storage units of the plurality of energy storage units based on at least one parameter, the connection arrangement including at least one connection type between the two or more energy storage units, the at least one parameter including a temperature associated with the exhaust of the vehicle, the connection arrangement including one of a first connection arrangement and a second connection arrangement, the first connection arrangement including a first connection type, the second connection arrangement including a second connection type, determining the connection arrangement including one of:
• switching from the first connection arrangement to the second connection arrangement based on the at least one parameter;
• and
• switching from the second connection arrangement to the first connection arrangement based on the at least one parameter;
• and
• cause the two or more energy storage units to one of provide power and terminate providing power to the vehicle using the determined connection arrangement.

A system comprising a connection management unit, CMU, and a plurality of energy storage units, the CMU comprising at least one switch electrically connectable to at least one of the plurality of energy storage units, the CMU being electrically connectable to the plurality of energy storage units, the plurality of energy storage units being electrically connectable to a heater associated with a catalytic converter of an exhaust of a vehicle, the plurality of energy storage units being configurable to provide power to the heater:

• the CMU being configured to:
• determine a connection arrangement of two or more energy storage units of the plurality of energy storage units based on at least one parameter, the connection arrangement including at least one connection type between the two or more energy storage units, the at least one parameter including a temperature associated with the exhaust of the vehicle, the connection arrangement including one of a first connection arrangement and a second connection arrangement, the first connection arrangement including a first connection type, the second connection arrangement including a second connection type, determining the connection arrangement including one of:
• switching from the first connection arrangement to the second connection arrangement based on the at least one parameter;
• and
• switching from the second connection arrangement to the first connection arrangement based on the at least one parameter;
• and
• cause the at least one switch to switch from a first switch state to a second switch state or from the second switch state to the first switch state based on the determined connection, the switching of the switch causing the two or more energy storage units to provide power to the vehicle using the determined connection arrangement.
