Vehicle energy storage system control methods and method for determining battery cycle life projection for heavy duty hybrid vehicle applications

A method for equalizing a storage parameter for a vehicle energy storage system having two or more energy storage banks associated therewith, the method comprising:

• identifying an active period of operation for the vehicle;
• determining whether the value of a defined storage quantity for a first energy storage bank differs from the value of said defined storage quantity for a second energy storage bank by a threshold amount;
• during a motoring operation of the vehicle, applying discharging energy from said one of said first and second energy storage banks to said motoring operation if the value of said defined storage quantity for said one of said first and second energy storage banks differs from the value of said defined storage quantity for said other of said first and second energy storage banks by said threshold amount.

A method for generating an energy storage control parameter for a vehicle energy storage system, the method comprising:

• receiving energy storage electrical property information;
• and
• estimating, from said energy storage electrical property information, a storage bank temperature.

A method for controlling the operating range of one or more energy storage banks in a vehicle energy storage system, the method comprising:

• determining a point at which the energy storage bank has reached a threshold value with respect to an end of life (EOL) condition;
• and
• responsive to said threshold value, reducing at least one of an energy storage bank operating parameter and an energy storage bank operating range.
