1AK-GROUP develops battery solutions for electric vehicles and electric transport. Such projects require not only battery assembly, but also engineering adaptation to a specific platform: voltage, capacity, weight, layout, temperature range, BMS, safety and data exchange with the vehicle.
In 2025, 1AK-GROUP produced a pilot-industrial batch of traction LFP batteries for the Belarusian Belgee EX50 electric vehicle. This project demonstrates the holding’s ability to work not only with standard battery solutions, but also with complex tasks for electric transport.
EV batteries are designed with regard to platform requirements, driving mode, charging infrastructure, temperature conditions and safety requirements. Solutions may include BMS, active balancing, telemetry, a metal case and project-specific cable routing.
| Model / project | Voltage | Capacity | Features | Temperature range | Cycle life | Application |
|---|---|---|---|---|---|---|
| ZUBR Li-Ion BelGee | 307 V | 54 kWh | EV BMS, active balancing | -20…+60°C | 3000+ cycles | BelGee electric vehicles, special projects |
What is considered when developing an EV battery
| Parameter | What is important |
|---|---|
| Voltage | Compatibility with the vehicle electric platform |
| Energy capacity | Driving range and operating mode |
| Weight and dimensions | Placement in the vehicle body and impact on vehicle balance |
| BMS | Control, protection, balancing and data exchange |
| Temperature range | Operation in seasonal and climatic conditions |
| Safety | Protection against emergency modes and battery condition monitoring |
| Charging infrastructure | Compatibility with charging equipment |
| Serial status | Prototype, pilot batch, industrial supply |
A Li-Ion battery solution is selected not only by capacity. Correct configuration requires consideration of application, voltage, operating mode, placement conditions, BMS requirements and the level of integration into equipment.
| Selection criterion | What to consider |
|---|---|
| Application | Urban mobility, modular system, battery block, electric vehicle |
| Voltage | Equipment or project requirements |
| Capacity | Required operating time or energy reserve |
| Chemical system | Li-Ion / LFP — according to safety, service-life and operating-mode requirements |
| BMS | Protection, balancing, monitoring, data exchange |
| Dimensions and weight | Installation space and layout requirements |
| Temperature range | Operating and storage conditions |
| Interfaces | CAN / RS485 / telemetry — if required |
| Project status | Standard solution, prototype or custom development |
For compact electric equipment and urban mobility, weight, dimensions, service life and safe charging are important. For modular solutions and battery cabinets, scalability, parameter control and integration into an engineering system are important. For electric vehicles and special-purpose electric transport, project adaptation, BMS operation, temperature range and platform requirements are important.
For electric vehicles and special-purpose electric transport – design adaptation, BMS operation, temperature control, and platform requirements.
