The invention relates to a battery system, in particular for a hybrid drive, comprising a housing and a plurality of battery cells arranged within the housing, said cells being combined to give a cell block, wherein a container having a variable inner volume is arranged between the cell block and at least one housing wall, by means of which container the cell block can be braced relative to the housing, wherein the container is filled with a curable or cured medium.

A method for controlling torque reduction of a hybrid vehicle includes: determining a discharging torque control factor of a motor and a charging torque control factor of the motor based on a current state of charge of a battery that supplies electric power to the motor and a threshold state of charge of the battery; calculating a torque of the motor corresponding to driving torque reduction request of a traction control system (TCS) based on a discharging limit torque of the motor that the discharging torque control factor is reflected in and a charging limit torque of the motor that the charging torque control factor is reflected in; and calculating a torque of the engine corresponding to the driving torque reduction request based on the calculated torque of the motor and a request torque of the traction control system.

A circuit arrangement (11) for supplying an electric vehicle with power comprises a battery (10) with a first terminal (16) and a second terminal (17), and a reference potential terminal (12) directly connected to the second terminal (17) of the battery (10). The circuit arrangement (11) further comprises a first output (18) that is coupled to the first terminal (16) of the battery (10) via a first switch (20) and that is configured to be connected to an electric machine (33) of the electric vehicle, and a second output (19) that is coupled to the first terminal (16) of the battery (10) and that is configured to be connected to a power net (34) of the electric vehicle. Furthermore, a power system (32) for an electric vehicle comprises the circuit arrangement (11), an electric machine (33) and a power net (34). The first output (18) is coupled to the electric machine (33) and the second output (19) is coupled to the power net (34).

A solar powered vehicle topper unit and systems and methods for the same are provided. A solar energy harvesting device is electrically connected to an electronic display within a housing. The solar energy harvesting device is located above the housing. The solar energy harvesting device has a first footprint, and the housing has a second footprint which is smaller than the first footprint.

A vehicle includes an auxiliary battery and one or more accessory loads. An accessory load command is modulated such that the auxiliary battery outputs a discharge current to an accessory load. The discharge current has, in addition to a current component for driving the accessory load, an alternating current (AC) component to cause a temperature of the auxiliary battery to increase.

Disclosed is a battery pack, which includes a plurality of unit battery modules, each unit battery module having a plurality of battery cells accommodated in an inner space thereof, the plurality of unit battery modules being structurally connected successively in one direction; and a pack case configured to cover the plurality of unit battery modules, wherein each unit battery module has two side plates forming opposite side surfaces thereof, and wherein one of the side plates of any one of the unit battery modules and one of the side plates of another one of the unit battery modules adjacent thereto are engaged with each other to form a single common wall.

In an electric vehicle having a primary battery powered source of energy with a primary electric motor driven and connected to one or more ground engagement wheels of the electric vehicle, has a device called a sprocket used for collecting energy form the inner rim edge of the rear wheel of the electric vehicle. This sprocket mechanism device collects this energy then transfers that energy to alternators one and two on its mounted framework in the trunk compartment by way of a chain. The two alternators with its sitting pilot voltages, then transfer it by required electrically conductive cables sending energy to the battery bank source thus completing the on board charging system cycle.

An ECU of an electric vehicle supplies a target rotation speed RT having a value corresponding to the temperature TB of a main battery to a cooler, controls a main DC/DC converter such that the SOC of an auxiliary battery is in a predetermined range SOCL to SOCH less than 100% when a cooling fan in the cooler is driven at the target rotation speed (RT), and controls the main DC/DC converter such that the SOC of the auxiliary battery is 100% when the cooling fan is not driven at the target rotation speed (RT).

A rechargeable motorized personal shopping and utility cart. Designed for elderly or infirm consumers who find it difficult to pull or push a manual utility cart, particularly on inclines, the electronic shopping cart would propel itself on demand. Designed in every aspect for the ultimate in convenience, the front of the unit would also feature an easy-access swing-open door which makes the loading and unloading of the electronic shopping cart far easier, even for extra tall items.

The motorized wheel accessory for a stroller is an after-market device that is configured to interface with a stroller in order to mobilize the stroller without the need for an end user to actually push said stroller. The motorized wheel accessory includes a frame that is configured to attach onto a rear axle of a stroller. The frame includes a power member that is wired to a motor. The motor is in mechanical connection with a pair of wheels. The pair of wheels propel the stroller. The frame may be adjustable to accommodate differently-sized strollers.
