Why it matters

Turn EV uncertainty into sales confidence

As EV volumes grow, traditional appraisal and sales processes aren’t enough. Buyers want reassurance about battery condition, real-world range and long-term ownership costs, and sales teams need credible answers they can trust.

ClearWatt gives dealerships a structured, repeatable way to assess EV health, present it clearly to customers and support ownership after the sale. The result is faster sales, more stable pricing and fewer avoidable aftersales issues, without adding operational complexity.

"One of our vehicles started to rapidly lose performance, barely able to travel 60 miles on a full charge, despite the SoH value from the BMS reporting 95% battery health. We tested the vehicle with ClearWatt and within a 2-minute OBD scan we’d received a report highlighting a major cell imbalance, which was immediately followed up by a ClearWatt engineer. This case underlines the importance of a comprehensive deepdive that goes further than just the BMS value, and we’re very pleased to be using ClearWatt’s leading solution to achieve this level of insight without any compromises on convenience."

"Since introducing ClearWatt’s EV Flash Reports, our EV sales process has become far more transparent and efficient. They’ve become an essential part of how we build trust with customers and close sales. It’s hard to imagine selling electric cars without them now."

"We know from our customers that battery health can be a worry, but by bundling in ClearWatt’s battery health check this can help us give customers the confidence they need to make the switch… It all helps towards our mission to accelerate the adoption of electric vehicles."

"The battery is the main thing that prospective buyers are nervous about when buying a second hand EV. It’s the single most expensive part of the car and buyers want to know if it is in good shape and has a long life ahead of it. Clearwatt allows you to definitively prove the state of your battery ahead of sale so you can be confident what you are selling - and the buyer is confident about what they are taking on."
