An apparatus for displaying the charging of the battery of an electric vehicle has a charging connector mounted on an outer panel of a vehicle body of the electric vehicle, a lid openably mounted on the panel in covering relation to the charging connector and a cavity defined in the outer panel, and a display panel disposed in the cavity for displaying a period of time required until the battery is fully charged and/or a charged capacity of the battery. The driver of the electric vehicle can easily recognize the remaining time required until the battery is fully charged and a percentage of the fully charged capacity of the battery to which the battery is presently charged, from outside of the electric vehicle. The driver is not required to confirm the state of charge of the battery with an indicator on a battery charger or within the passenger's compartment of the electric vehicle, but can easily confirm the state of charge of the battery from outside of the electric vehicle.

Apparatus for displaying battery charging of electric vehicle

A battery assembly has a temperature control mechanism for effecting cooling or heating unit batteries for operation in a desired temperature range. First heat-exchange planar members of respective heat-transfer plates are sandwiched between the unit batteries that are arranged in an array, and second heat-exchange planar members thereof are held against transverse narrow side walls of the unit batteries. The unit batteries and the heat-transfer plates are securely fastened together by holder plates. Heat produced when the unit batteries are in operation is transferred through the first and second heat-exchange planar members of the heat-transfer plates and dissipated into an appropriate cooling medium, such as atmospheric air or another cooling fluid, through a heat-exchange.
