Plug-in hybrid applications

Managing a traction pack in a PHEV presents a unique set of challenges:

• The pack may be operated in two distinct modes, Charge Deplete or Charge Sustain, each with its own behavior.
• While the method of SOC calculation in the Charge Deplete mode is similar to the one in EVs, and the method in the Charge Sustain mode is similar to the one in HEVs, the integration of these two methods is not straightforward and requires some finesse.
• PHEV conversions must perform not one but two separate SOC evaluations: the actual SOC of the traction pack, and the reported SOC to achieve the desired behavior in the vehicle.

Over the years, Elithion has developed a significant experience in the PHEV (Plug in Hybrid Electric Vehicle) field, and has developed elegant PHEV algorithms and solutions.
 

⇪PHEV conversions

Several companies convert the Toyota Prius to PHEV by adding a PHEV pack and a charger. A significant number of these companies use the Lithiumate BMS to manage their PHEV packs.

Elithion's BMS technology was used by a pioneer in PHEV conversion, Hybrids Plus. That company converted a number of Prius and Ford Escape HEVs to Plug-in hybrids. Elithion has continued that process, having converted an HEV to PHEV for the Global-E X-Prize team and a Ford Escape HEV to PHEV for a large cell manufacturer.
