Disclosed herein are electric vehicles with various characteristics. For example, electric vehicles with at least two energy storage systems are described. As another example, electric vehicles with liquid temperature regulated battery packs are described. As yet another example, electric vehicles with high voltage battery limit optimization are disclosed. And, as another example, electric vehicles with dual-battery system charge management are described.

Electric vehicle battery management

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.

Bus bar and PCB for vehicle battery

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.
