VoltzIQ Smart BMS

VoltZIQ supports lithium-ion (NMC, NCA) and lithium iron phosphate (LFP) packs from 7S to 30S (24V to 120V+). Standard configurations include 13S (48V), 15S/16S/17S (48V/60V), 20S (72V), 24S/26S/28S (96V–100V), and 30S (120V+) for ESS and industrial applications. Custom configurations are available through an OEM RFQ.

Passive balancers burn off excess energy as heat and only work while charging. VoltZIQ's active balancer transfers energy between cells using an inductive topology, consuming up to 10x less power. It operates in all three states — charging, discharging, and standby — to keep cell voltages matched continuously. Balanced cells mean more usable capacity per cycle, longer pack life, and more accurate SOC readings.

BMS MOSFETs and power stages generate heat under continuous high current. In a 45°C Indian summer, a poorly designed BMS can push internal component temperatures past safe limits, accelerating degradation and causing de-rating. VoltZIQ's optimised PCB layout achieves a +31°C rise at 60A continuous and just +17°C at 50A, against a ~57°C industry average. Lower rise means sustained performance, longer component life, and no forced de-rating during peak-load climbs.

Lightning, inverter switching, and motor transients generate voltage spikes that can destroy logic and MOSFETs. VoltZIQ uses a 3-tier Transient Voltage Suppression (TVS) array that clamps spikes in under 1 nanosecond, shunting destructive energy before it reaches any sensitive component. This protects the BMS, the battery, and the entire vehicle electrical system.

On downhill stretches, regenerative braking can push current back into the pack at high rate. If the BMS treats this like a charger-fault and disconnects, drivers are left stranded — a real problem on ghat roads and flyovers. VoltZIQ's steep-slope back-charging logic safely absorbs regenerated energy within the pack's tolerance, without a nuisance disconnection or damaging the charging MOSFETs.

Yes. Overvoltage, undervoltage, overcurrent, and short-circuit protection are implemented in hardware and run completely independently of CAN, RS485, or Bluetooth links. If telematics drops, connection is lost with the charger, or a bus is disrupted, the pack stays protected — true fail-safe behaviour.

CAN 2.0B for vehicle and charger integration, RS485 (Modbus RTU) for ESS and industrial stacks, and Bluetooth 5.0 BLE for the mobile app. Optional 4G telematics hardware adds GPS, cloud streaming, remote lock, and OTA firmware updates.

Yes. OEM customization covers CAN message IDs and frame formats, SOC/SOH behaviour mapping, protection thresholds, firmware parameters, mobile app branding, connector pin-outs, and mechanical form factor. Customizations are scoped through an RFQ so that both engineering and commercial terms are agreed before sampling.

A firmware-level authenticated lock prevents the pack from powering an unrecognised vehicle. Combined with a secondary overvoltage tamper alarm and optional 4G telemetry, the system can raise an alert and even enable remote immobilization if theft is detected. This is especially valuable for battery swapping networks and leased fleets.

Balancing current is up to 2A per cell pair, with a balancing resolution of approximately 3 mV. The algorithm operates on the difference between cell voltages and continues to level the pack in all three operating states.

Continuous discharge ratings span 30A through 500A depending on model (60A/80A/100A/150A/200A/300A/500A standard). Peak current up to roughly 2× rated is allowed for short bursts (uphill starts, cargo launch) through intelligent current derating, which safely accommodates transients instead of nuisance-shutting down.

VoltZIQ uses a hybrid Coulomb-counting + voltage/OCV-correction algorithm with drift compensation, giving a non-jumping SOC display. Cold-weather pre-heat logic also improves winter-time accuracy and start reliability.

Yes. Firmware can be updated over Bluetooth (BLE) from the mobile app and over the air through the 4G IoT module. This lets you tune balancing parameters, safety thresholds, and communication behaviour across deployed packs without a teardown — ideal for field quality programs.

Operating ambient range is −20°C to +85°C with full protection functionality. Natural convection cooling, so no fan is required. Pack-level thermal management (where required) is designed together with your pack integrator.

VoltZIQ BMS is designed for CE and RoHS compliance, with protection and communication architecture aligned to AIS-156 for EV battery safety. Certification copies and test summaries are provided against an NDA and can be discussed through the /certifications page.

Yes. The BMS streams cell voltages, pack temperature, current, SOC, and alerts over CAN to an optional 4G telematics module. The VoltZIQ cloud platform provides live GPS tracking, geofencing, remote lock, fleet analytics, and a REST API plus webhooks for integration with your own systems. See the IoT Platform page for details.

The MOSFETs are opened by a hardware-triggered protection path within microseconds — independently of firmware and communication. The fault is latched and requires a cleared condition to recover, preventing toggling, arc damage, and cable or connector meltdown.

Standard warranty is 12 months against manufacturing defects in normal operating conditions. OEM-level warranty terms (duration, field-return process, and exchange) are negotiated as part of the OEM RFQ agreement.

Submit an RFQ from this page or /rfq with your cell configuration, voltage, current rating, and annual volume. Our engineering team responds within 24 business hours with the datasheet, recommended model, sample lead time, and pricing for your volume tier.

Standard engineering samples typically ship within 1–3 weeks depending on configuration and documentation (CAN protocol, drawings, test report). Production lead times depend on volume and are confirmed with the commercial quotation.
