Integrated Mobile Power Systems (IMPS)

The Prohelion Integrated Mobile Power System utilises a modular, flexible design to produce battery packs in multiple configurations. The packs designed for 2019 BWSC Challenger Class use five power sub-modules and one control module to provide systems with over 5kWh capacity, encapsulated in a strong and light carbon-fibre/fibreglass case.

Custom solution are also provide for other vehicle configurations such as Cruiser using our modular 1kWh blocks.

RACE PROVEN

A reliable, proven architecture based on 20 years of solar car learnings and race tested in events around the world

Prohelion IMPS

The Prohelion Integrated Mobile Power System utilises a modular, flexible design to produce battery packs in multiple configurations. The packs designed for 2019 BWSC Challenger Class use five power sub-modules and one control module to provide systems with over 5kWh capacity, encapsulated in a strong and light carbon-fibre/fibreglass case.

Cruiser class packs are custom built to any size using 1kWh modules.


Marand Configuration

  • 418 cells: 38 series, 11 parallel
  • Nominal Voltage: 138V
  • Capacity: 5318 Wh

Mitsuba Configuration

  • 406 Cells: 29 series, 14 parallel
  • Nominal Voltage: 105V
  • Capacity: 5165 Wh
1kWh

Battery Cells

The Prohelion IMPS uses the LG LG18650MJ1 cell as the building block of the pack.  This cell has the highest energy capacity of its class, ensuring an out of the box, competitive battery.


Battery Sub Module

Each Battery Sub Module is rated at approximately 1kWh, monitored by a Prohelion CMU and can be combined to make larger packs of any capacity.

Control Module

The Control Module is the brain of the IMPS controlling the pack using a Tritium BMS. It also provides safe state isolation, fusing, 12V functionality and CAN bus interface to monitor and control the Prohelion IMPS

Software and Tools

Monitoring of the Prohelion IMPS can be performed with Prohelion Software and our Android app which provides a live dashboard of key battery statistics over a wi-fi connection.

Physical Dimension and Layout

The box is constructed from carbon fibre with a fibreglass internal lining, providing a strong yet lightweight containment with the benefit of an electrically insulated interior. A lightweight, transparent lid is provided for ease of inspection of the battery cells. The battery enclosure includes the ability to be sealed upon completion of scrutineering.

The completed challenger class box has the following dimensions: H: 95mm, W: 460mm, D: 670mm.  Cruiser class boxes are built to accommodate the specified battery.

*Please note dimensions are still subject to change and may change slightly depending on your final configuration and requirements
