For the past few months I've been focused on two parts of the E23 that probably aren't very exciting from the outside: the battery system and the power distribution unit (PDU). The motor and inverter are already sitting in the workshop, which is a great feeling.
Wiring isn’t just connecting components. The E23 electrical system defines behaviour - controlling when power flows and what the vehicle refuses to do.
Designing the E23 battery system: how real-world constraints led to a modular, high-voltage architecture with scalable energy and consistent performance.
For the E23, battery design is driven less by stored energy than by current limits, thermal behaviour, and mass. These constraints shape performance long before capacity becomes the limiting factor.
With performance targets defined, the next step was unavoidable: choosing a battery system, a motor, and an inverter. On paper, that sounds straightforward. In reality, it took months and quietly shaped almost every decision that followed. Power Is Simple. Systems Are Not. Power is easy to write down: P = V
Before locking in motors, batteries, or gearing for the E23, we needed to define what the car actually needed to be. The first goal wasn’t a number. The E23 needs to feel exciting and dynamic, something you’re not going to find the limits of in the first ten
Before the first tube was drawn, we defined the E23’s size envelope — the real‑world limits that shape everything from trailer fit to handling. This post shows how a simple footprint decision unlocked the entire design.
Design starts with a sketch, right? Not quite. For E23, the first step was defining the use case—because purpose drives every line.
We’re starting E‑Division to create electric machines that feel alive. The E23 is our first chapter, purpose-built for pure driving joy.
