JKBMS PLINK Module (P-Link-CR-V2.0) — Soft Parallel Connection & Inverter Communication Interface
IMPORTANT COMPATIBILITY REQUIREMENT: Your BMS must have BOTH a port labeled “GPS” AND a 4-PIN CAN/RS485 interface to use this P-LINK module. Older BMS versions commonly use 3-PIN CAN/RS485 interfaces and are NOT compatible. Check both ports on your BMS before ordering.
The JKBMS PLINK Module is a multi-protocol communication interface for JKBMS HC and HCR series Smart BMS. It serves two key functions: enabling soft parallel connection between multiple battery packs, and providing RS485 and CAN communication links to inverters for integrated energy storage system control.
⚠️ Requires CAN interface. Compatible with JKBMS HC and HCR series only. Not compatible with Standard series or JK-PB Inverter BMS series.
Key Features
- ✅ Soft parallel connection via CAN — coordinate multiple battery packs without hardware parallel port
- ✅ Inverter communication via RS485 and CAN — compatible with mainstream inverter brands
- ✅ Multi-pack SOC synchronization and coordinated charge/discharge management
- ✅ Compatible with both HC and HCR series JKBMS
- ✅ Compact PCB design — easy to integrate into battery enclosures
- ✅ Plug-and-play connection via JKBMS CAN port
Communication Interfaces
- CAN — soft parallel between BMS units; inverter CAN communication
- RS485 — inverter RS485 communication
Compatibility
- ✅ JKBMS HC series: JK-B1A8S10P-HC, JK-B2A8S20P-HC, JK-B2A8S30P-HC, JK-B2A24S series HC
- ✅ JKBMS HCR series: JK-B1A8S10P-HCR, JK-B2A8S20P-HCR, JK-B2A8S30P-HCR, JK-B2A24S series HCR
- ❌ Standard series: Not compatible (no CAN interface)
- ❌ JK-PB Inverter BMS series: Not compatible
Soft Parallel vs Hard Parallel — Which Do You Need?
| Feature | PLINK Module (Soft Parallel) | Parallel Module (Hard Parallel) |
|---|---|---|
| Connection type | CAN communication-based | Hardware parallel interface port |
| BMS requirement | HC or HCR series | HCR series only |
| SOC synchronization | ✅ | ✅ |
| Inverter communication (CAN/RS485) | ✅ | ❌ |
| Requires hardware parallel port | ❌ Not required | ✅ Required |
| Best for | Multi-pack setups + inverter integration | Large-scale high-current systems (HCR only) |

The plug for the CAN/RS485 doesn’t fit the socket on the JKBMS
Our product descriptions explicitly state that the P-LINK module supports only 4-pin CAN/RS485 interfaces and requires a BMS that supports GPS plus RS485/CAN for operation.
