Battery Management Systems

The BMS is the unsung hero making sure your battery pack doesn’t turn into a very expensive brick or that your solar-powered cabin doesn’t go dark mid-movie. We design and optimize battery management systems to ensure optimal performance, safety, and longevity.

Why You Need a Battery Solutions Partner

Battery engineering comes with some serious hurdles. We help you navigate:

Materials Selection

Choosing the right chemistry for performance and longevity

Device Actualization

Bringing battery concepts into real-world applications

System & Performance Optimization

Ensuring efficiency, stability, and integration

Quality & Safety

Mitigating risks and meeting regulatory standards

Cost & Time Constraints

Reducing overhead with smarter design strategies

Art & Science

The nexus of these is the sweet spot in battery engineering

BMS Design Services

Our battery engineering team brings deep expertise in high- and low-voltage applications, active and passive balancing, and both single-board and distributed architectures. We specialize in:

  • CANBus communication system design
  • Shunt and inductive current measurement
  • Solid-state and contactor switching BMS

From circuit design to PCBA layout, validation, testing, and manufacturing transition, we provide tailored solutions to meet your needs.

Protecting Battery Integrity

Safety isn’t an afterthought—it’s engineered into every system we design. Our BMS solutions integrate:

  • Over/under-voltage, over-current, and over-temperature protections
  • Advanced heating and cooling controls
  • EMI shielding, heat rejection, and enclosure designs for physical protection
  • Embedded software for SOC (state of charge), SOH (state of health), charging control, and fault detection

Battery systems are complex, but with the right expertise, they don’t have to be a liability. Let’s build a safer, smarter energy solution together.

Power Management

We've created multiple custom power management devices, typically DC to DC control for fuel cells and battery systems. These products, and others we've created, generally use less than 4kW and require a combination of lightweight and high-efficiency power conversion. We've combined power systems that mix solar, wind, generators, and fuel cells for remote power backup systems in rail crossings, in remote locations like the Arctic Circle or mountainsides, and other remote infrastructure backup power.

Designing power management systems is only half the fun; batteries are another passion of ours. We've created lightweight and high-efficiency DC/DC for military UAVs, underwater ROVs, and vehicles.

Custom Electronics and Control Software

Managing and optimizing the flow of electricity for efficient and reliable device or system operations.
