Dynexus uses pattern recognition to make a powerful battery health measurement technique even better

Charged

Measuring battery health and safety continuously is an important challenge—lithium-ion batteries can experience several challenges over their lifetimes such as unintended capacity loss, short circuits and thermal runaway. We need to understand the remaining capacity and state of health throughout a battery’s lifecycle.

CARB proposes new rules for defining EV battery health

Charged

Buying a pre-owned EV presents a new concern for buyers to beware of—the health of the vehicle’s battery. All batteries degrade over time, and there’s no simple way for a buyer to know how much of its original range a used EV retains. Some older EVs—notable the air-cooled Nissan LEAF—have poor records in this department.
