What is The Voltt?

The Voltt is About:Energy's web-based platform for battery cell selection. It gives engineering teams evidence-based insight at the earliest stage of product development, enabling faster, lower-risk and right-first-time cell choices that directly influence product range, lifetime, cost and charging performance.

Key Features

Cell Library

Explore our Cell Database: Access over 300 high-performance cells from leading manufacturers including Molicel, LG, Samsung, EVE, and Amprius. Search, filter, compare, and shortlist the right cells faster with trusted, engineering-grade data.

Simulate

Run virtual battery tests using real-world data. Simulate is powered by our in-house test facility in London, where we generate high-precision data under controlled conditions. This enables you to analyse drive cycle responses, predict end-of-life performance, all without waiting months for physical results.

This helps you answer key questions such as:

  • Which cell can complete my mission profile?
  • Should I choose a pouch or cylindrical battery pack?
  • Does the Molicel P60B outperform its predecessor P50B?

Powermap

We run thousands of our Equivalent Circuit Model (ECM) simulations in the cloud to find the best performance that your battery can deliver. Compare multiple cells side by side, visualising power, C-rate, current, internal resistance, and heat generation across varied conditions.

This helps you answer key questions such as:

  • How do resistance and heat change with SOC?
  • What peak power is possible at 40 °C and 24% SOC?
  • Which EVE cell matches Molicel's power at 10 °C?
