Claim 16:
17. A method of cooling one or more components of an electric lawnmower comprising a drive unit and a mowing unit, the method comprising:
coupling the drive unit to the mowing unit, wherein:
the drive unit comprises a battery, a power electronics unit, and a drive motor powered by the battery,
the mowing unit comprises a set of cutting blade units such that each unit in the set of cutting blade units comprises a blade enclosure and a cutting blade at least partially surrounded by the blade enclosure,
the blade enclosure comprises a fluid passage, which is fluidically connected to at least one of the battery, the power electronics unit, and the drive motor of the drive unit after coupling the drive unit to the mowing unit, and
the mowing unit comprises a thermal-liquid pump, extending into the fluid passage of the blade enclosure of one unit in the set of cutting blade units and is mechanically coupled to a mowing-unit electric motor; and

operating the mowing-unit electric motor thereby causing the cutting blade of each unit in the set of cutting blade units to spin and also causing the thermal-liquid pump to pump a thermal liquid through the fluid passage and between the fluid passage and at least one of the battery, the power electronics unit, and the drive motor of the drive unit.
