1. A vehicle comprising:
a first battery housing to house a plurality of first battery modules;
a second battery housing to house a plurality of second battery modules;
an air cooling system to cool the plurality of first battery modules and the plurality of second battery modules, the air cooling system including:
a compressor;
a condenser;
a first evaporator coil that includes a first side at which warm air is received and a second side at which cool air exits after having passed through the first evaporator coil;
a second evaporator coil that includes a first side at which warm air is received and a second side at which cool air exits after having passed through the second evaporator coil;
a first blower to direct a first portion of the cool air from the second side of the first evaporator coil into the first battery housing;
a second blower to direct a first portion of the cool air from the second side of the second evaporator coil into the first battery housing; and
a third blower to direct a second portion of the cool air from the second side of the first evaporator coil and a second portion of the cool air from the second side of the second evaporator coil into the second battery housing; wherein
a volume of the first battery housing is larger than a volume of the second battery housing; and
a combined volume of the first portion of the cool air from the second side of the first evaporator coil directed by the first blower and the first portion of the cool air from the second side of the second evaporator coil directed by the second blower is greater than a combined volume of the second portion of the cool air from the second side of the first evaporator coil and the second portion of the cool air from the second side of the second evaporator coil directed by the third blower.
