Hybrid and Electric Battery Tests

Millbrook provides a wide range of test methods to assess the life, safety and performance of vehicle batteries. These include:

Millbrook also offers a range of electric machine and inverter tests and provides full vehicle test facilities including the ability to crash EVs and FCVs.

Strip and inspection for EV batteries in Millbrook's Battery Test Facility

Battery Strip and Inspection

After completing a battery test, Millbrook’s skilled team safely strips them down to component parts, while measuring key parameters, such as distances, torques, voltages, and resistances. A detailed photographic record can also be provided.

A high-resolution video link allows real-time interaction. This can be especially useful in situations where the battery pack is damaged, making it difficult to specify in advance what is of interest.

Millbrook conducts abuse testing of lithium ion batteries for applications including rail, aircraft, grid storage and electric vehicles, all of which can be followed up with battery strip and inspection.

Other capabilities include:

  • Battery repairs, such as fuse replacement, module replacement and software reflashing
  • Return shipping of batteries after testing
  • Secure battery disposal after testing
