EV battery testing firm Generational has added a new, more in-depth feature to its diagnostics platform.
The new cell-level voltage testing capability allows dealership staff to detect voltage imbalances between individual cells, potentially detecting problems that may not yet appear in overall battery health ratings.

According to Generational, this allows non-technical staff at dealers to identify potential issues early, since weak cells could reduce range, affect charging and potentially require expensive battery module replacement.
Testing ‘offers used EV buyer reassurance’
Generational says the cell-level testing can support more accurate vehicle appraisals and boost confidence in the used EV market, since two batteries with similar overall states of health can behave very differently in real-world use if one has a significant cell imbalance.
It said that its more in-depth testing could help dealers to reassure more technically minded EV buyers, supporting their asking price for used vehicles.
Oliver Phillpott, CEO of Generational, said: “For EV batteries to operate as intended, every cell in the pack needs to remain balanced. When one cell begins to drop out of line, it can limit the performance of the entire battery, affecting range and drivability, and in some cases leading to expensive module replacement.
“For most dealers, getting a meaningful read on EV battery condition has meant sending it to a workshop – slow, costly and often not practical at the point of appraisal.
“Generational’s tool enables anyone on the forecourt to run a test, yielding results that are understandable and actionable. For retailers, this means more confident pricing and a reduction in risk.”
