Victron Energy temperature sensor for BMV battery monitor
This precise temperature sensor is designed for the Victron Energy BMV-702 and BMV-712 smart battery monitors, allowing for accurate measurement and display of the battery's temperature. With this accessory, the system can perform temperature-compensated charging, significantly increasing the battery's lifespan and safety.
Why is measuring battery temperature important?
The performance and lifespan of lead-acid and lithium batteries are greatly influenced by temperature. Too high or too low temperatures can:
- reduce available capacity,
- accelerate battery aging,
- pose safety risks in case of overheating.
Through accurate temperature measurement and compensation, the charger can automatically adjust to the appropriate charging voltage, ensuring optimal conditions for the energy storage.
Main features and benefits
- Continuous monitoring of battery temperature
- Support for temperature-compensated charging via the BMV-702/712 battery monitor
- Increased battery lifespan and reliability
- More accurate state of charge and status indication
- Easy, quick connection to existing Victron Energy system
Applications
The temperature sensor is ideal for any system where reliable power supply and long battery life are important:
- RVs, caravans, and camping systems,
- onboard batteries of boats and yachts,
- off-grid solar systems,
- emergency lighting, uninterruptible power supplies (UPS),
- industrial and remote monitoring systems.
Operating principle in brief
The sensor measures the temperature near the battery, typically mounted close to the terminal. The measured value is transmitted to the connected BMV monitor, which:
- evaluates the temperature data,
- corrects the charging voltage if necessary,
- displays the temperature and calculated parameters.
As a result, the battery always receives optimal charging adjusted to the current temperature.
Easy connection to Victron Energy system
The sensor is specifically designed for the BMV-702 and BMV-712 monitor inputs, making installation straightforward:
- Mount the sensor to the battery terminal or close to it.
- Connect the factory cable to the BMV temperature input.
- Activate and set the temperature function in the BMV menu.
No complicated configuration is needed; the system is immediately capable of processing temperature data after connection.
Why is it worth using this temperature sensor?
- Optimized battery charging across all temperature ranges
- Lower maintenance costs due to longer lifespan
- Higher system efficiency and more reliable operation
- Safer operation even under extreme conditions
If the BMV monitor is already present in the system, this temperature sensor provides significant additional protection and accuracy for energy management with a small investment.
Who is it recommended for?
- Those who want to protect their batteries in the long term
- Those operating high-value battery banks (e.g., in solar systems)
- Those expecting reliable, continuous power supply from their vehicle or boat
- Those wanting to utilize the full functionality of Victron BMV monitors
Summary
This temperature sensor is a key accessory for the BMV-702 and BMV-712 battery monitors. It allows the system to consider not only voltage and current but also the battery temperature, achieving more accurate battery protection, more efficient charging, and longer lifespan. If reliable energy management is important, this accessory is an almost essential part of the Victron Energy system.
