A system configured to monitor a primary battery and a backup battery in a vehicle. The system includes one or more active components, such as a controller, that switch power between the primary battery and the backup battery. The system is configured to switch power from the primary battery to the backup battery when the power level of the primary battery drops below a threshold level. The system is generally implemented on a vehicle having an internal combustion engine. Power from the primary battery is used to start the engine. The backup battery is typically a swappable and interchangeable battery, such as a cordless power tool battery. In one example, the vehicle does not include an alternator.

The invention relates to a system for locking and/or unlocking a power battery under a vehicle chassis, comprising a plurality of tools, each of which includes elements for aligning said tool relative to the battery along a longitudinal axis and along a transverse axis, elements for bearing against the underside of the chassis and enabling balancing, and locking and/or unlocking elements for actuating an attachment bolt between a locked configuration, in which the battery is locked under the chassis, and an unlocked configuration, in which the object is released.

A method of exchanging an electrical energy storage system (EESS) in an electric vehicle includes: positioning an electric vehicle in x and y directions on an EESS exchange station; after positioning, raising the electric vehicle to a predetermined height using a first lift; after raising the electric vehicle, raising an EESS lift toward the electric vehicle until the EESS lift is correctly positioned relative to a first EESS; after raising the EESS lift, removing fasteners that secure a first EESS to the electric vehicle; placing an EESS conveyor underneath the EESS lift; after placing the EESS conveyor, lowering the first EESS onto the EESS conveyor using the EESS lift; after lowering the first EESS, removing the first EESS and instead placing a second EESS underneath the electric vehicle; after placing the second EESS underneath the electric vehicle, raising the second EESS toward the electric vehicle using the EESS lift until the second EESS is correctly positioned relative to the electric vehicle; after raising the second EESS, fastening the second EESS onto the electric vehicle; and after fastening the second EESS, lowering the electric vehicle using the vehicle lift.

A battery replacement system configured to replace battery for an electric vehicle includes a control system, a first self-propelled battery module and a second self-propelled battery module in communication with the control system. The first self-propelled battery module is configured to detach from the electric vehicle upon receiving an appropriate command from the control system, and second self-propelled battery module is configured to be mounted to the electric vehicle upon receiving an appropriate command from the control system. The first self-propelled battery module and the second self-propelled battery module are capable of moving automatically to an predetermined position. An using method of the battery replacement system is also provided.

An electrified vehicle includes a chassis, a front axle, a rear axle, a vehicle component including at least one of a pump, a compressor, or an alternator, an energy storage device including a plurality of batteries, and an electromagnetic device coupled to both (a) at least one of the front axle or the rear axle and (b) the vehicle component. The electromagnetic device is powered by the energy storage device and configured to selectively provide a mechanical output to (i) the at least one of the front axle or the rear axle and (ii) the vehicle component.

Aspects of the disclosure include systems and methods for leveraging a thermally triggered adhesive release for battery service. An exemplary method can include receiving a battery pack having an adhesive layer at an interface between a cooling plate and a component. A heating fluid is directed through an enclosed volume of the cooling plate and a temperature of the adhesive layer is measured. Responsive to determining that the temperature has reached a target temperature, a load is applied to the component until the component is removed.
