Ultra low voltage drives

Safer, Simpler, Better

Our Ultra Low Voltage technology offers previously unobtainable levels of safety, simplicity and reliability.


Our drives operate at the voltage of a single electrochemical cell, without voltage conversion.

Using an ultra-low-voltage battery and motor eliminates virtually all electrical hazards through all stages of the product life cycle, from manufacturing to disposal. This means that accidents or inexpert maintenance interventions no longer bring electrical safety risks. It also means that complex and costly safety systems are avoided, making our systems ideal in difficult or demanding environments such as agriculture, mining or transport generally.

The difference in hazard level between our technology and common EV drive systems using main battery voltages 400 volts and above is difficult to overstate. As newer applications using higher voltages enter the market, this difference only increases. Ignoring all other advantages, these avoided risks, alone, are a sufficient reason to consider our systems.


The ULV motor is simplicity itself. There are no conventional “windings”, no brushes, and no complex liquid cooling systems. It can be manufactured using common machine tools and either automated or manual assembly processes.

The simplicity of our design approach extends to the whole drive system. As the motor connects directly onto the DC bus at cell voltage, no voltage changes are required, eliminating the usual associated losses, simplifying design and reducing cost.

Charging is likewise simple and allows for adaptation to whatever the customer needs. The charger can be as simple as a bank of parallel-connected solar cells, with no other components required.

Typical EV configuration

EV Configuration with our ULV drive


The simplicity of our technology allows the design of drive systems from 0.1 to 1000kW that are robust and reliable, with multi-redundant elements, and a real degree of "future-proofing".

Highly Robust

Design for high power at low voltages requires heavily parallel configurations, which automatically brings very high levels of redundancy. High redundancy means that loss of a single battery, battery circuit or motor element causes only slight performance degradation. This “soft-fail” characteristic means our systems will keep operating long after a typical HV system would have failed.

No Software Required

All our drive systems use analog controls for robust performance and to remove technology obsolesce risks. No software licenses or programming tools are required to support the system, so our systems should still be serviceable several decades from now. Our systems are also inherently "hack-proof".

User Serviceable

The use of single-cell parallel batteries means cells and main system elements can be swapped in the field with simple tools, offering high levels of serviceability. Cells can safely be removed and replaced while the system is live.


Our systems can concurrently use batteries of different states of charge, different sizes and different chemistries, and with full efficiency. Together with the ability for user battery swapping, this provides a simple upgrade path when new batteries and battery types become available.

So, if you have an application which previously seemed too risky for an electric drive solution, we can show you an alternative approach.
