Order the in-stock EVD-M-200, review EVDrive's made-to-order Smart PDU and BetterBMS boards, purchase engineering time, or send your application details so EVDrive can configure the right system.
Review BetterBMS, Smart PDU, and available EVDrive powertrain hardware in one place.
Purchase standard engineering support or add limited integration support to a qualifying hardware order.
BetterBMS separates close-to-cell measurement from pack-level decision making, so EVDrive can configure the system around the physical pack, its duty cycle, and the vehicle it serves.
Read the system architecture guide →Satellite boards stay near the cells and modules they supervise. A low-voltage IsoSPI communication pair links satellites to the master, which is especially useful when a pack occupies more than one enclosure.
Each satellite can collect voltage data from up to 18 series cell groups and up to five cell temperatures. The master uses that information for state of charge, state of health, balancing, and operating limits.
The master manages main and precharge contactors, then communicates pack state and charge and discharge limits to the vehicle control unit through the external controller area network.
Separate internal and vehicle networks keep peripheral devices and vehicle-control communication distinct. Configuration and firmware updates are handled over controller area network using supported industry-standard adapters.
Voltage sensing, temperature sensing, and communications use separate connection paths. Each satellite voltage-sense input is fused to help protect the module and its sense wiring.
