Abstract: Disclosed herein are battery systems for electric vehicles. An electric vehicle may include a first battery. The first battery may be configured to power various low voltage systems. For example, the first battery may provide the power to start the vehicle. The vehicle may include a second battery. The second battery may be configured to power one or more electric motors for propelling the vehicle. The first battery may include a housing. The housing may include a battery monitoring system. The battery monitoring system may include a PCB that is secured to at least one bus bar. The bus bar may include an integrated shunt. The shunt may be coupled to circuitry on the PCB that is configured to monitor current.

Abstract: A battery level management system for an electric vehicle during a powered down and uncharged period is disclosed. A current output from a low voltage battery of the electric vehicle being above a threshold can be sensed to wake up a control unit associated with the low voltage battery without waking up or fully powering other control units. Upon waking up, the control unit associated with the low voltage battery can start monitoring the current output from the low voltage battery and controlling the power drawn from the low voltage battery by enabling or disabling other control units to manage the remaining low voltage battery power level.

Abstract: The present disclosure relates to devices, systems, and methods for providing electric power to low voltage systems of a vehicle. In some embodiments, a vehicle includes a low voltage battery pack and at least two systems configured to draw power from the low voltage battery pack. The at least two vehicle systems can be operable in a first mode while connected to the low voltage battery pack, and can be operable in a second mode while disconnected from the low voltage battery pack. The second mode may be utilized when the vehicle is connected to an external low voltage power source. The second mode may be a low power mode in which the at least two systems have reduced functionality or are prohibited from operating simultaneously.
