Abstract
Systems and methods for electric vehicle battery systems with replaceable parallel electric vehicle battery modules are described herein. The electric vehicle battery system includes a plurality of electric vehicle battery modules connected in parallel. Each electric vehicle battery module includes a battery. Each electric vehicle battery module can also include a balancing circuit in electrical communication with a current path from the battery to an electric vehicle battery module output node. Each electric vehicle battery module also may have a current sensor in electromagnetic communication with the current path between the battery and the balancing circuit. The current sensor can be configured to sense a current level between the battery and the balancing circuit. The balancing circuit can be configured to balance the current level sensed by the current sensor of each electric vehicle battery module.
