BMS-EV – Use Your EV Battery as Home Energy Storage and Lower Your Electricity Bills
Batteries from electric vehicles are the best-tested cells on the market. They undergo rigorous automotive safety testing – far more demanding than standard home energy storage systems.
With BMS-EV products, using this technology in your home is simple and enjoyable!

Why Are EV Batteries Better?
🔋 Certified Automotive-Grade Cells
EV batteries undergo testing according to UN 38.3, UL 1973 and IEC 62933 standards – the most rigorous safety standards for lithium-ion cells. Typical home energy storage doesn’t need to meet such stringent requirements.💰 30-70% Savings Compared to New Energy Storage
EV batteries retain 70-80% capacity after their service in the vehicle. With a capacity of 60-100 kWh, they can power an average home for an entire week! The cost of such a solution is a fraction of the price of new energy storage.🌱 Ecology and Battery Second Life
Instead of disposal – reuse. You extend the battery’s life by another 10-15 years, reduce your carbon footprint and support a circular economy. New EU regulations (2023/1542) require 70% recycling of lithium batteries by 2030.⚡ 5-8x Less Stressed Than in the Vehicle
At home, the battery operates under much milder conditions – without sudden accelerations, extreme temperatures and constant fast charging. This means longer lifespan and stable operation.How Does It Work?
☀️ PV → Inverter → Home – solar energy powers your home ⚡ Inverter → BMS-EV – surplus goes to storage 🔋 BMS-EV ⇆ EV Battery – intelligent energy management
Compatibility
BMS-EV is compatible with batteries from the most popular electric vehicles:- Nissan Leaf (24-62 kWh)
- Tesla Model S/3/X/Y
- BMW i3
- Volkswagen ID.3/ID.4
- Hyundai Ioniq/Kona
- and many others…
Safety First
⚠️ Working with high voltage is dangerous – that’s why BMS-EV has multi-layered protection systems:- Continuous monitoring of each cell’s voltage
- Temperature control with automatic shutdown
- Insulation resistance analysis and leakage protection
- FAULT mode – immediate shutdown when anomalies are detected
- Compliance with UL 1974 and IEC 62933-5-3 standards
Net-Billing and Savings
Since net-billing was introduced, energy returned to the grid is billed cheaply (0.25 zł/kWh), while purchased energy is expensive (0.65+ zł/kWh). BMS-EV stores surplus in the EV battery and allows you to use it in the evening when solar energy is no longer available.- Self-Consumption Up to 90%+ Instead of 30%
- Return on Investment in 3-5 Years
- Independence from the Grid During Outages
