An embodiment of the disclosure is directed to a battery module, comprising a plurality of battery cells that each include a cell terminal formed from a first metal, and a contact plate including a conductive plate that is formed from a second metal and a first metallic surface layer (e.g., a surface coating or clad material) arranged on a first side of the conductive plate that is formed from the first metal, wherein part of the contact plate is arranged as a plurality of bonding connectors that form direct electrical connections to the cell terminals of the plurality of battery cells. In some designs, a second metallic surface layer (e.g., a surface coating or clad material) may further be arranged on a second side of the conductive plate and may also be formed from the first metal.

A battery protector includes analog frontend circuitry coupled to a hibernate mode input terminal that is one of configured to couple to a high voltage connector terminal when the system is connected to an external load or charger to define an active mode and configured to float when the system is disconnected from the external load or charger to define a hibernate mode. The analog frontend circuitry is configured to provide a signal at an output thereof to distinguish, in the absence of an external ground connection, between connected and floating conditions for the hibernate mode input terminal. Digital logic is coupled with the output of the analog frontend circuitry, the digital logic providing a digital signal to control whether the battery protector is operating in the active mode or the hibernate mode based on the signal at the output of the analog frontend circuitry.

Methods and systems are provided for a battery encapsulant. In one example, a method may include a battery encapsulant surrounding one or more battery cells of a vehicle battery, where the encapsulant comprises a Young Modulus between 0.05 to 0.15 GPa after being cured.

A battery for use in electronic devices and which is safely ingested into a body and a related method of making the battery. The battery includes an anode, a cathode and a quantum tunneling composite coating. The quantum tunneling composite coating covers at least a portion of at least one of the anode or the cathode and provides pressure sensitive conductive properties to the battery including a compressive stress threshold for conduction. The compressive stress threshold may be greater than a pre-determined applied stress in a digestive tract of the body in order to prevent harm if the battery is ingested. The battery may include a waterproof seal that extends between the quantum tunneling composite coating and a gasket separating the anode and cathode to inhibit the battery from short circuiting in a conductive fluid below the compressive stress threshold.

Provided is a protection device for a vehicle electrical component capable of preventing damage to a predetermined electrical component due to hitting by a battery, and also capable of reducing noise/vibration. The disclosure is a protection device which protects a starter in a vehicle in which a battery and the starter are disposed to face each other with a space therebetween in an engine room of the vehicle in which components constituting a power plant or a power train are supported by a vehicle body via a mount and a bracket. The skid block serving as the protection device includes bracket attachment portions attached to a transmission attachment portion of the bracket, and a skid block main body extending upward from the bracket attachment portions and gradually away from the bracket extension portion, and having a distal end portion positioned between the battery and the starter and facing the battery.
