Drivers can safely charge their electric vehicles to 100% capacity without damaging the battery, the RAC has confirmed, debunking a widespread myth that has fuelled range anxiety among UK motorists.
The breakdown service giant said modern EVs are fitted with sophisticated battery management systems that prevent overcharging and optimise battery life. The outdated advice to avoid full charges stems from older nickel-cadmium batteries, which suffered from 'memory effect' - a problem that doesn't affect today's lithium-ion technology.
The RAC actually recommends regular full charging, explaining that it allows the battery management system to perform complete balancing cycles across all cells. This process helps maintain the battery's overall health and extends its lifespan - the opposite of what many drivers have been told.
The guidance directly contradicts the cautious approach adopted by many EV owners, who often limit charging to 80% or 90% in a misguided attempt to preserve their battery. This self-imposed restriction has contributed to range anxiety, deterring potential buyers from making the switch to electric.
For British drivers considering EVs, accurate battery care information is crucial as the government pushes ahead with its net-zero strategy. Ministers continue promoting electric vehicle adoption through charging point grants and infrastructure investment, making clear guidance from trusted sources like the RAC vital for consumer confidence.
The intervention highlights the urgent need for public education as EV technology advances rapidly. With Britain's charging network expanding and more drivers embracing electric motoring, dispelling such myths will be essential to maximise the benefits of cleaner transport and ease transition anxieties.
