What Refrigerated Truck Auxiliary Battery Covers
Cold chain's core KPI: zero temperature break. One 10-minute refrigeration interruption = ¥50–500K cargo loss = full compensation + client loss. Industry pain: lead-acid unstable voltage (fluctuating cooling efficiency), terminal corrosion may cause instant power loss, deep-cycle life only 3–6 months. GSP/cold chain regulations mandate full-process temperature traceability. PLB, founded 2014, dual-circuit redundancy — seamless millisecond main/backup switching, zero cold-chain break, zero cargo loss. BMS built-in data logging meets GSP traceability requirements. Steady 12.8V output, ±1 °C temperature fluctuation.

10 ¥50 —— 10-Minute Power Loss = ¥500K Cargo Damage — Who Bears the Risk?
Fresh produce and vaccine transport — 10-minute refrigeration interruption causes 5–10 °C rise, severe quality damage or total spoilage. Cargo value ¥50–500K per load. Power loss = full compensation. Lead-acid terminal corrosion causes poor contact, aging BMS may falsely cut output — "one power outage ruins one delivery" is every cold chain operator's worst nightmare.
Zero chain break = zero cargo loss = zero compensation. PLB dual-circuit: main feeds refrigeration + backup on standby. Any main circuit anomaly triggers seamless millisecond backup switch — refrigeration never stops. Dual independent BMS isolation — single group failure doesn't affect the other. Zero cold-chain risk.

|---|---|---|
| Outage risk | Present, single circuit | Zero, dual circuit |
| Switchover | Manual restart | Millisecond automatic |
| Cargo liability | ¥500,000 per load | Zero |
| Compliance | At risk | Fully compliant |
3-6 —— Lead-Acid Dies in 3-6 Months — Refrigerated Truck Battery Replacement Chaos
The pain is specific: 3-6 —— Lead-Acid Dies in 3-6 Months — Refrigerated Truck Battery Replacement Chaos In daily operation, lead-acid or manually managed packs lose capacity between scheduled checks, maintenance teams cannot inspect every unit, and the failure surfaces only when the load is already at risk.
5-year zero replacement + constant temperature = dual cold-chain guarantee. PLB's LiFePO₄ pack and BMS monitor cell voltage, temperature and SOC continuously, alert before a weak cell becomes a failure, and are sized to the application's load profile.
| Conventional / manual | PLB LiFePO₄ | |
|---|---|---|
| Monitoring | Periodic checks | Continuous BMS |
| Fault warning | At failure | Threshold alerts |
| Maintenance | Scheduled visits | Exception-based |
| Service life | 2–3 years | 6,000+ cycles |
—— = GSP Cold Chain Mandates Full Temperature Traceability — Power Loss = Data Loss = Violation
Cold chain regulations require full-process traceable temperature records. Vaccine transport GSP violations fined ¥500K-2M. Temperature monitoring equipment powered by lead-acid loses data when battery runs low. Power loss stops loggers — upon arrival, incomplete records = violation = rejection = full compensation + administrative penalties.
Complete traceable data throughout — zero regulatory risk. PLB cold-chain BMS built-in data logging — continuously records voltage/current/temperature/SOC. Even if refrigeration loses power, BMS independently powered data module continues 24+ hours. Complete GSP/cold chain compliance. USB/Bluetooth export.
| Lead-acid | PLB reefer version | |
|---|---|---|
| Data continuity | Lost when charge falls | Continuous |
| Recording after a power cut | None | 24 hours or more |
| GSP compliance | Non-compliant | Fully compliant |
| Fine exposure | ¥500,000–2M | Zero |

Frequently Asked Questions
The questions fleet managers and truck owners ask most about LiFePO₄ parking-AC batteries in the Refrigerated Trucks scenario — ±1 °C (temperature stability), and what it takes to qualify.
What has to change on the vehicle before a LiFePO₄ pack goes into the Refrigerated Trucks scenario?
The pack fits the original battery box at the same 12 V or 24 V system voltage with the same terminal layout, so no bodywork change is needed. Typical models for Refrigerated Trucks builds are LL-PC200 (reefer).
Does output stay flat through a whole Refrigerated Trucks rest period?
The pack runs the air conditioner through the rest period without idling the engine, and deep-cycle life replaces the one-year lead-acid replacement cycle. Key figure: ±1 °C (temperature stability).
How is the pack sealed and thermally managed in Refrigerated Trucks duty?
The sealed pack is rated for engine-bay heat and road vibration, with BMS protection against over-current and over-temperature.
Is a special charger needed in the Refrigerated Trucks scenario?
The alternator recharges the pack while driving, and the BMS limits current so the vehicle circuit stays inside its rating.
What warranty and after-sales support apply in the Refrigerated Trucks scenario?
Standard products carry a full warranty backed by lifetime technical support, with terms confirmed on the quotation; export packing is UN 38.3-certified with MSDS. Tell us the air-conditioner rating, nightly hours and battery-box dimensions — our engineers size the pack and recommend the matching model within 24 hours.
