AxSDB
AI Software-Defined Battery
AxSDB turns battery packs into configurable, observable, and remotely maintainable power platforms.
Built on bidirectional Buck-Boost power conversion, AxSDB separates battery core voltage from system output voltage.
One battery core can support multiple output voltages, remote diagnostics, OTA-ready control, and AI-assisted monitoring for small power and small energy storage systems.
What AxSDB Changes
A battery is no longer a fixed pack — it becomes a configurable, observable, updatable platform.
From fixed voltage
From fixed voltage to configurable output
Traditional battery packs are tied to fixed series count and fixed voltage. AxSDB uses BiBuckBoost to create configurable output voltage from a lower-voltage battery core.
From blind packs
From blind battery packs to remote visibility
Telemetry, AI-assisted monitoring, and remote diagnostics make field systems easier to maintain.
From one pack per product
From one pack per product to platform reuse
One battery core can support 12V, 24V, 36V, 48V, or 60V platforms through software-defined control.
Built by Alai, for Real Energy Devices
AxSDB is led by Alai Xu, a power electronics and embedded systems builder focused on software-defined batteries, bidirectional Buck-Boost converters, BMS integration, telemetry, remote diagnostics, and OTA-ready control.
The project started from a simple engineering problem: most battery packs are still designed around fixed series count and fixed voltage, while real devices often need different output voltages, field visibility, remote maintenance, and safer upgrade paths.
AxSDB is our answer to that problem: a software-defined battery platform that combines large-format battery cells, bidirectional Buck-Boost power conversion, AI-assisted monitoring, and remote diagnostics.
The current stage is engineering prototype and lab validation. We are validating converter behavior, thermal limits, protection logic, telemetry, and real application scenarios before moving toward evaluation boards and selected pilot projects.

Applications
Where AxSDB fits today — small power, small energy storage, DC UPS, robots, two-wheelers, solar, and remote-maintained modules.
Small Two-Wheeler Power
Stable 36V / 48V / 60V output from a lower-voltage battery core.
Robot Power System
Configurable DC output for compact mobile machines.
12V / 24V DC UPS
Controlled DC backup for routers, cameras, terminals, and field devices.
Small Energy Storage
Large-format cells become configurable energy modules for portable and home backup.
Solar Battery System
Solar-input-ready architecture with controlled battery and load paths.
Remote-Maintained Battery Module
Telemetry and diagnostics make field systems easier to manage.
Bidirectional Energy Flow
AxSDB works as an intelligent energy router between input, battery, and software-defined output.
Why BiBuckBoost Matters
A single power stage handles charging and output, with software-defined behavior at every level. The same hardware can Buck-charge the battery and Boost a system bus, while AI-assisted telemetry and remote diagnostics make field systems easier to operate.
Buck for Charging
When input voltage is higher than the battery voltage, AxSDB uses Buck control to charge the battery safely.
Boost for Output
When the battery voltage is lower than the required system voltage, AxSDB uses Boost control to create a stable output bus.
Bidirectional Energy Flow
One power stage handles both directions. The same hardware charges the battery and serves the load — direction is software-defined.
Software-Defined Output
Output voltage, current limit, power limit, and protection logic are configured by software, so one battery core fits multiple platforms.
AI-Assisted Monitoring
Telemetry and trend analysis support remote diagnostics. AxSDB adds visibility — it does not replace functional safety design.
OTA & Remote Diagnostics
Strategy and output configuration can be updated remotely. Faults can be inspected without sending a technician to the field.
Buck vs Boost Mode
Buck stores energy safely when input voltage is higher than the battery. Boost creates a stable output bus when battery voltage is lower than the system bus.
Buck Charging
Input voltage higher than battery voltage.
Boost Output
Battery voltage lower than the required system bus.
Software-Defined Voltage Ladder
One battery core. Multiple voltage platforms. The output bus is configured by software.
Fewer Series Cells vs Traditional Pack
Traditional battery packs are tied to fixed series count and fixed voltage. AxSDB separates battery chemistry from output voltage, enabling easier platform reuse.
DC UPS Smooth Output
Smooth backup behavior with controlled DC output for routers, cameras, terminals, and field devices — whether input power is available or not.
Solar Charging + Load Output
Solar-input-ready architecture: AxSDB can connect a solar charging path with a controlled DC output for real devices.
AI Monitor & Remote Diagnostics
AI-assisted monitoring helps detect abnormal trends and supports remote diagnostics. The controller remains an engineering control system, not an autonomous safety replacement.
Traditional Pack vs. AxSDB
A battery is no longer a fixed pack — it becomes a configurable, observable, updatable platform.
| Aspect | Traditional Battery Pack | AxSDB |
|---|---|---|
| Series structure | Fixed series count | Fewer large-format cells |
| Output voltage | Fixed voltage | Configurable output voltage |
| Behavior | Difficult to adapt | Software-defined behavior |
| Diagnostics | Hard to diagnose remotely | AI-assisted monitoring and remote diagnostics |
| Platform reuse | Replacement depends on pack design | Easier platform reuse |
| Updates | Field firmware changes are difficult | OTA-ready control |
