Improving POS-Terminal Reliability & Efficiency with YMIN Supercapacitors
Point-of-Sale (POS) terminals often suffer downtime, data loss or interruptions when batteries are low, during swap-outs, or under unexpected power loss. YMIN proposes integrating supercapacitors (EDLCs) as immediate backup power to sustain operation during these critical transitions.
1. Instant Backup Power
Supercaps deliver near-instantaneous energy to bridge gaps during battery replacement or outages. This maintains POS operation integrity, prevents reboot cycles and ensures transaction continuity—enhancing system uptime and user experience.
2. Extended System Lifespan
Compared with conventional rechargeable batteries, supercapacitors tolerate far more charge/discharge cycles—commonly ≥ 500,000 cycles—with capacity retention often > 80% over time. This dramatically reduces maintenance and replacement frequency.
3. Fast Recharge Capability
Supercapacitors can recharge within seconds to minutes—even from very low residual battery voltage—thereby minimizing downtime and removing long recharge delays typical of chemical batteries.
YMIN Supercap Performance Characteristics
- Lifespan: ≥ 500k cycles, < 20% degradation over extended use.
- Power Density: ~1–10 kW/kg—able to supply high surge currents.
- Efficiency & Eco-profile: > 95% charge/discharge efficiency; low internal resistance; minimal energy loss .
- Thermal Range: −40 °C to +70 °C operational—suitable for diverse environments.
- Safety Features: Built-in protection against over-voltage, short-circuit, and thermal runaway.
Recommended Application & System Integration
YMIN’s supercapacitor modules are compact and suitable for inclusion in modern POS designs. Engineers can place them in parallel with the main battery to serve as a short-duration power buffer. Selection criteria include:
- Required hold-up time during battery swap
- Surge current demands of the POS hardware
- Available package volume/footprint
- Operating temperature range
- Integration of safety circuitry (e.g. voltage clamping, current limiting)
While the public announcement refers to a “capacitor selection table,” no detailed BOM was publicly released; interested designers should contact YMIN for datasheets and sizing guidelines (e.g. capacitance, voltage, ESR vs expected load profile)
Engineer Summary
Integrating YMIN supercapacitors into POS terminals provides several system-level advantages. Continuous uptime is ensured by preventing transaction failures during sudden power loss or battery replacement. The extended cycle life of supercapacitors—10 to 100 times longer than conventional batteries—significantly reduces maintenance requirements and replacement costs. Their high efficiency, fast recharge capability, and low energy loss improve overall power management, while the broad operating temperature range guarantees reliability under diverse environmental conditions. In addition, built-in safety mechanisms protect against over-voltage, short-circuit, and thermal risks, making the solution both robust and dependable for long-term operation.
Conclusion:
For engineers designing or maintaining POS terminals, integrating YMIN supercapacitors is a practical way to enhance reliability, reduce downtime, and support long-term operation, especially under high transaction rates or challenging environments.
