A battery assembly according to an exemplary aspect of the present disclosure includes, among other things, a battery array and a foam shell that surrounds the battery array.

An apparatus for controlling a driving mode of a hybrid vehicle and a method thereof are provided in which a specific cell, which constitutes a battery, is prevented from being overdischarged by adjusting a switching time point of a driving mode (an electric vehicle (EV) mode or a hybrid electric vehicle (HEV) mode) based on a cell voltage change of the battery mounted in the hybrid electric vehicle. The apparatus for controlling the driving mode of the hybrid vehicle includes a battery including a plurality of cells, a voltage sensor to measure voltages of the cells in the battery, and a controller to control a switching time point from the EV mode to the HEV mode based on the voltages of the cells in the battery, as measured by the voltage sensor.

A vehicle controller for a vehicle including a drive source including an electric motor includes: a sense-of-beating producer configured to acquire a total required torque which is a required torque of the entire vehicle and configured to derive a total target torque corresponding to the total required torque as applied to a predetermined engine combustion cycle; and a target motor torque deriver configured to, based on the total target torque, derive a target motor torque for torque control of the electric motor. The vehicle controller controls the electric motor based on the target motor torque.

A control method for a swappable battery pack set of electric vehicles (EVs), wherein each of the EVs has a main battery pack set and at least a swappable battery pack set simultaneously. The control method comprises the following process of uninstalling the swappable battery pack set from a first EV, before charging the swappable battery pack set; executing a charge unlocking procedure, before charging the swappable battery pack set; executing a charge locking procedure, after charging the swappable battery pack set; and installing the swappable battery pack set to a second EV after executing the charge locking procedure.

An electrical family car, including: an electrically driven motor; and wheels with a radius larger than 90 cm. In such cars one of the dominating energy losses is directly related to the car axial to wheel friction. The car efficiency could therefore be increased by increasing the car wheel diameter which could yield a larger traveling distance for the same axial to wheel friction related energy loss.

An apparatus, method and computer program product are provided for providing availability of designated electric vehicles during an emergency. In one example, the apparatus receives a mobility pattern of a user of an electric vehicle and adds the user and the electric vehicle to an exception list based on the mobility pattern. During an emergency, the apparatus ensures a predetermined amount of state of charge for each electric vehicle that is electrically coupled to an external power source and is indicated in the exception list.
