Why data privacy is critical in smart charging services

As the world becomes more connected and reliant on technology, concerns about data privacy have increased. Smart charging services for electric vehicles (EVs) are no exception. While these services offer numerous benefits, including reduced costs and increased efficiency, they also collect and process significant personal data. Understanding why data privacy matters in smart charging products are essential to handle it correctly.

In this blog post, we’ll explore why data privacy matters in smart charging services and what steps Synergi takes to ensure full privacy.

What private data could be collected and why privacy matters

Smart charging services like Synergi use advanced algorithms and data analysis to optimize EV charging. These products collect information about the user’s charging habits, such as when they typically charge their vehicle, how long it takes to charge, and how much energy is consumed. This information is analyzed to create a personalized charging schedule that minimizes energy consumption and reduces costs.

Smart charging services collect and store sensitive data that can be vulnerable to privacy breaches if not properly secured. Companies must implement robust security measures to protect this data and gain the trust of their customers.

Therefore, when it comes to smart charging services, data privacy matters for several reasons:

Personal data: Smart charging services collect a significant amount of personal data, including when you charge your EV, how much energy is used, and how much it costs. This data can be used to profile your habits, preferences, and location.

Security risks: Any collected data is potentially vulnerable to security breaches. In theory, this could include hackers gaining access to your data or even taking control of your EV charging.

Third-party access: Data collected by smart charging services could be shared with third-party companies for marketing or other purposes without your knowledge or consent.

Privacy laws: In many countries, there are strict laws in place to protect personal data. Companies not taking data privacy seriously risk facing legal action and damaging their reputation.

How we ensure smart charging and EV data privacy at Synergi

At Synergi, we take data privacy very seriously. We understand that our customers trust us with their personal data, and we work hard to ensure this trust is not misplaced. Here are some of the steps we take to ensure data privacy:

Anonymous data: We collect anonymous data where possible to minimize the amount of stored personal information. For example, we may collect data on the average energy usage of our customers, but we do not collect data on individual use unless necessary. Also, data is not our business; we won’t sell your data – it’s yours.

Data encryption: We encrypt all personal data collected to protect it from potential security breaches. This means that no one can access our customers’ personal data. 

Data storage: We never save or store vehicle login information (username, password) on Synergi. Also, we keep all personal data in secure locations with strict access controls. This ensures that only authorized personnel can access the data.

Consent: We obtain consent from our customers before collecting any personal data. This includes explaining what data we collect, how it’s used, and whom it’s shared with.

Transparency: We are transparent about our data privacy practices and provide our customers with clear information on how their data is collected, stored, and used in our Privacy Policy.

Compliance: We comply with all relevant data privacy laws and regulations, including the General Data Protection Regulation (GDPR) in the European Union. In addition, we refer to My Car My Data for external credibility from FIA that the usage of this GDPR data is entirely done by the books.

Continuous improvement: We regularly review our data privacy practices and make improvements where necessary. This includes reviewing our policies, procedures, and technology systems.


Data privacy is a crucial issue in smart charging services. While the benefits of this technology are clear, it is vital to ensure that personal data is collected, stored, and used responsibly and ethically. At Synergi, we take data privacy seriously and work hard to protect our customer’s data. By taking these steps, we can ensure that our customers can trust us with their data and enjoy the benefits of smart technology without compromising their privacy.
