Methods for using cycle life data to protect electric vehicle battery health during use of bidirectional charger

An apparatus to protect battery health during bidirectional charging events, the apparatus comprising:

• a processor;
• and
• a memory communicatively coupled to the processor, the memory comprising instructions that, when executed by the processor, are configured to cause the processor to:
• receive cycle life data, said cycle life data comprising one or more historical energy cycle events of one or more electric vehicle batteries;
• determine anticipated energy needs of a building;
• determine an amount of discharge of the one or more electric vehicle batteries required to offset the anticipated energy needs of the building by a predetermined amount;
• determine based on the cycle life data whether discharging the one or more electric vehicle batteries by the predetermined amount will be harmful to the health of the one or more electric vehicle batteries;
• and
• discharge the one or more electric vehicle batteries to offset the anticipated needs of the building if it is determined that discharging the one or more electric vehicle batteries by the predetermined amount will not be harmful to the health of the one or more electric vehicle batteries.

A system connected to an electric grid that protects battery health during bidirectional charging events, the system comprising:

• a charger comprising an operations management component, wherein the operations management component comprises a processor in communication with one or more electric vehicles, wherein the processor is programmed to:
• receive cycle life data, said cycle life data comprising one or more historical energy cycle events of one or more electric vehicle batteries;
• determine anticipated energy needs of a building;
• determine an amount of discharge of the one or more electric vehicle batteries required to offset the anticipated needs of the building by a predetermined amount;
• determine based on the cycle life data whether discharging the one or more electric vehicle batteries by the predetermined amount will be harmful to the health of the one or more electric vehicle batteries;
• and
• discharge the electric vehicle battery to offset the anticipated needs of the building if it is determined that discharging the one or more electric vehicle batteries by the predetermined amount will not be harmful to the health of the one or more electric vehicle batteries.
