True Parallel Hybrid
Most hybrid power solutions put a battery box next to a diesel generator and call it a system. Johank ENERGYPACK is different: diesel and battery are designed together, share one AC bus, and are controlled by one EMS through one HMI.
Diesel AND battery — not diesel OR battery
In low-load periods, the battery carries the site silently. When the load rises, diesel and battery work together on the same AC bus. The EMS decides when to start, stop, charge or assist — automatically.
This is what makes it a true parallel hybrid. The diesel module and LFP battery are coordinated by one EMS and can support the same site load together. This reduces diesel runtime during low-load periods and keeps the operator workflow close to a familiar genset.
Industry default vs. Johank approach
Separate battery module + separate diesel genset. Multiple suppliers, multiple control systems, on-site integration, commissioning risk.
One OEM-engineered machine. One EMS, one HMI, synchronised output. Single-point lift. Familiar operator workflow.
Inside the ENERGYPACK
Diesel module, LFP battery, EMS, switchgear, cooling — engineered together in a single weatherproof enclosure.
Iso view
Diesel and battery share one enclosure, one cooling system and one switchgear assembly.
Topology — top view
Engineered layout puts the LFP battery, diesel module, EMS controller and AC bus where they belong.
One HMI. One workflow.
Operators see diesel and battery on one screen. No multi-vendor integration. No interface risk. Operators trained on standard diesel gensets can run ENERGYPACK in one day.
Familiar HMI
Voltage, frequency, hours, fuel — operators see what they expect, plus battery SOC and EMS status.
In-house EMS
Load sharing, battery SOC, diesel start/stop, charging and protection — all automatic, all coordinated.
Open protocol
RS485 / Modbus RTU / Ethernet TCP/IP. Integrates with fleet management and SCADA. Secondary development supported.
Every unit reports its data
Every ENERGYPACK unit reports operating data to the fleet operator and the Johank service team. Monthly reports available for customer billing and ESG documentation.
