Coolant Reservoir Tank

A coolant reservoir tank, comprising:

• a first compartment configured to receive and retain a first portion of a liquid coolant, wherein the first compartment is configured to be in fluid communication with a first liquid cooling circuit;
• a second compartment configured to receive and retain a second portion of the liquid coolant, wherein the second compartment is configured to be in fluid communication with a second liquid cooling circuit;
• a dividing wall separating the first compartment from the second compartment, which includes an opening formed at a lower portion thereof;
• a fill port;
• and
• a separating port positioned between the fill port and the dividing wall, which includes a first fluid opening to the first compartment and a second fluid opening to the second compartment.

• a first circuit comprising one or more components, wherein one of the components is a battery;
• a second circuit comprising one or more components, wherein one of the components is an inverter system circuit;
• and
• a coolant reservoir tank for retaining and circulating liquid coolant in relation to the first circuit and the second circuit, the coolant reservoir tank comprising:
• a first compartment that is configured to receive and retain a first portion of a liquid coolant, wherein the first compartment is configured to be in fluid communication with the battery,
• a second compartment that is configured to receive and retain a second portion of the liquid coolant, wherein the second compartment is configured to be in fluid communication with the inverter system circuit,
• a dividing wall that separates the first compartment from the second compartment, and
