We help you develop safe battery-powered products. From battery selection and charging to power management and verification, we bring electronics and embedded software together around your product's requirements.
Contact SvepA well-designed battery solution gives your product greater freedom of use. It also requires a balance between operating time, size, charging, cost and the conditions in which the product will be used.
At Svep, we work with you to understand these requirements and develop a solution that fits the complete system. We can support a new product from the early design stages or investigate battery-related challenges in an existing one.
We help you select suitable primary cells, rechargeable cells or custom battery packs. Together, we compare capacity, peak-current capability, dimensions, temperature range and supplier documentation against your product's requirements.
The highest capacity is not always the best choice. A compact device, an industrial sensor and a portable instrument have different demands on charging, maintenance and service life. We make these trade-offs clear before the design is fixed.
We design battery chargers with safety as part of the complete product architecture. Starting with the selected battery chemistry and the manufacturer's specifications, we define the charging profile, voltage and current limits, temperature range and charge termination. The power supply, electronics and enclosure are considered together.
We review protection against overvoltage, excessive current and overheating, including how charging should be reduced or stopped outside the battery's permitted conditions. We also assess which protective functions must operate independently of the application firmware.
Verification is planned around normal use and relevant fault conditions, such as interrupted power, temperature-sensor faults and operation while charging. This gives your team evidence for the product safety assessment and subsequent compliance work.
Battery life depends on the complete product, not only the cell. We help you understand energy use during sleep, measurement, processing and communication, including short current peaks and unexpected wake-ups.
A measured power budget gives your team a clearer basis for design decisions. It can reveal opportunities to improve operating time, reduce battery size or extend service intervals, depending on your product and its use.
Embedded softwareWe help you improve battery life by looking at the electronics and embedded software together. Starting with your target runtime and operating conditions, we build a measured picture of where the product uses energy and which changes are worth making.
We measure current consumption during sleep, start-up, sensing and communication. By relating the measurements to the product's behaviour, we can identify unnecessary wake-ups, peripherals left running and standby losses that are easy to miss in an average reading.
Based on the findings, we review sleep modes, wake-up timing, sensor and radio activity, and the power circuitry. We then compare measurements before and after changes, checking that lower consumption does not compromise the product's required functionality or response time.
We help you verify battery performance under all operating conditions. Testing can cover runtime, charging behaviour, low-battery operation and performance across the agreed temperature range.
Using our in-house facilities and external laboratories where required, we connect test results with the design work.

We support you in identifying the battery and product requirements relevant to your application and intended markets. This helps establish the documentation and testing needed before market introduction.
Transport testing, battery safety and finished-product compliance are different parts of that work. UN 38.3 concerns relevant lithium battery transport tests, while IEC 62133-2 covers portable sealed secondary lithium cells and batteries.
We agree the scope of engineering verification and any external testing with you.
Quality and complianceBattery decisions affect more than the bill of materials. Replacement visits, charging downtime, serviceability and supply continuity can all influence the business case. We help you weigh these factors alongside performance and size.
We also consider battery replacement, disassembly and end-of-life handling during development. Sustainability benefits should be supported by the design and its intended use, rather than assumed from the battery chemistry alone.
Whether you need a focused investigation or support within a larger development programme, we define the scope and responsibilities together. Deliverables can include a power budget, battery comparison, design recommendations and verification results, with documentation and handover agreed from the start.
Are you developing a battery-powered product or looking to improve an existing design? We would be happy to discuss your requirements.
Tell us about the target runtime, size, operating environment and how the product will be charged or serviced. Together, we can identify the next step.
