Frequently Asked Questions

A Battery Management System (BMS) is an electronic control unit that monitors, manages, and protects a lithium battery pack. It continuously measures cell voltages, temperatures, and current to prevent overcharge, over-discharge, overcurrent, and thermal runaway. A BMS also provides accurate State of Charge (SoC) and State of Health (SoH) data to the vehicle or application. VoltZIQ BMS products are purpose-built for Indian EV applications with proprietary protection technologies.

ThermalSafe™ is VoltZIQ's proprietary thermal management technology. Through optimized PCB layout, efficient power component selection, and superior thermal engineering, VoltZIQ BMS boards achieve a significantly lower temperature rise during continuous high-current operation compared to conventional BMS designs. Lower temperature rise means higher reliability, longer component life, and fewer failures — critical for the extreme heat conditions common in Indian summers.

SurgeShield™ is VoltZIQ's multi-stage Transient Voltage Suppression (TVS) protection system. India's electrical environment presents unique challenges — including lightning strikes, frequent inverter switching transients, grid voltage spikes, and electrostatic discharge. Standard BMS boards often fail or degrade under these conditions. SurgeShield™ provides layered protection at multiple points on the board to block damaging transients before they can destroy sensitive electronics.

RegenGuard™ protects the BMS and battery pack during regenerative braking and downhill operation. Many BMS boards fail prematurely because they cannot handle the rapid energy being pushed back into the battery when a motor controller regenerates braking energy. RegenGuard™ actively manages these high reverse-energy events, preventing overvoltage damage and protecting both the BMS circuitry and the battery cells.

SafeCore™ ensures that the core battery protection functions (overvoltage, undervoltage, overcurrent, and temperature protection) continue to operate even if CAN bus, UART, or Bluetooth communication is lost or disconnected. Many competing BMS designs depend on a communication link to maintain protection — meaning a broken connector or software failure can disable safety functions. With VoltZIQ SafeCore™, the battery remains protected regardless of communication status.

VoltZIQ BMS products support LFP (Lithium Iron Phosphate) and NMC (Nickel Manganese Cobalt) battery chemistries — the two most common chemistries in Indian EV and energy storage applications. Firmware parameters can be configured for specific cell characteristics. OEM customers can request custom chemistry profiles as part of the customization package.

VoltZIQ BMS supports CAN bus, UART, RS485, and Bluetooth Low Energy (BLE) communication interfaces. This enables compatibility with a wide range of motor controllers, vehicle CAN buses, display units, chargers, and mobile applications. The mobile app communicates via BLE for real-time monitoring and configuration. OEM customers can request specific CAN protocol customizations.

Yes. VoltZIQ offers a full-featured mobile application for Android and iOS. The app provides real-time battery monitoring (voltage, current, temperature, SoC, SoH), fault alerts, battery configuration, and diagnostics — all via Bluetooth. The app supports English and Hindi language interfaces, making it accessible across India. OEM partners can receive a white-label version of the app with custom branding.

Yes. OEM customization is a core part of our offering. We can customize firmware parameters (voltage thresholds, current limits, SoC algorithms), CAN protocol, mobile app branding, and packaging for OEM partners. We also offer custom PCB configurations for specific current ratings and form factors. Contact our engineering team to discuss your specific requirements and volumes.
