Layout planning

Written by admin. Posted in Layout

The plan is to replace the internal combustion engine with a power/motor/inverter package with the following properties:

Enough energy storage to travel 50-60 miles at highway speeds

Using an estimate of 13kW to maintain 60MPH speeds on level surface, a 15kWhr pack size is the ideal point that fits, matches the weight and allows 60 mile range.

This implies a 70-80% discharge level for a 40 mile round trip that extends the cycle life of the cells significantly relative to the 100% depth of discharge cycle life of over 1000 cycles. This would achieve 20 years of life based on 300 40-mile trips per year.

Conversion begins

Written by admin. Posted in Motor Pull

With this tight engine compartment, it’s tough to do any layout planning so the engine needs pulling to get on with the next phase.

For our e-Car325i EVDrive-train conversion kits, regional installers will have access to online support videos and manuals which will contain the latest updates to lower the risk in providing conversions for customers.
