Detailed description

Designed for 12 V systems equipped with an alternator, the Smart BMS CL 12-100 by Victron Energy is an all-in-one battery management system (BMS) dedicated to Victron Smart 12.8 V lithium batteries. It provides protection and monitoring of each individual cell, managing up to 20 batteries for a maximum storage capacity of 84 kWh in a 12 V system. Specifically adapted for vehicles and boats, this BMS includes essential protection for the alternator and batteries.

Integrated Protection and Current Limitation

The Alternator/Starter Batt+ port of the Smart BMS CL 12-100 features electronic current limitation at approximately 90% of the fuse rating. For example, with a 100 A fuse, the input current is limited to about 90 A. This function protects the alternator from overload, preventing overheating and failure of 12 V alternators during prolonged operation at full power. It also prevents the lithium battery from excessive charging currents. The current flow is unidirectional, preventing discharge from the lithium battery to the starter battery.

Advanced Monitoring and Control Features

This BMS is equipped with a load disconnection and charging current disconnection output, allowing it to cut off DC charging sources or consumers in case of low/high cell voltage or excessive temperature. A pre-alarm output can activate a relay, LED, or sound alarm before battery disconnection. The remote on/off terminal allows interrupting charging via the alternator port or disabling the system entirely. Configuration and monitoring are performed via the VictronConnect app and Bluetooth, providing instant readings of key values for quick diagnostics.

« Optimized protection of 12V lithium systems with alternator »

Victron Energy’s Smart BMS CL 12-100 is a strategic solution for securely integrating 12.8 V Smart lithium batteries into the electrical systems of vehicles and boats. Its "all-in-one" design simplifies the architecture by consolidating cell protection and alternator protection into a single module. The key benefit lies in its ability to electronically limit the alternator’s charging current, a critical feature for preventing overheating and premature degradation of standard alternators, which are not designed for continuous maximum loads. This allows the use of stock alternators without costly modifications, increasing practical value for retrofit installations or first-fit setups where simplicity is a priority.

During installation, it is essential to consider the management of DC loads and charging sources. While the BMS includes disconnect outputs, external devices such as a BatteryProtect or a Cyrix-Li-Charge relay may be required for complete and secure system shutdown, particularly for "phantom" loads that can slowly discharge the battery. Victron’s expertise in energy management ensures compatibility with other products in the range, facilitating seamless integration into an existing Victron ecosystem. It is also critical not to underestimate the importance of configuration via VictronConnect to adjust disconnect thresholds and alarms, ensuring optimal protection against deep discharge and overcharging.

Frequently Asked Questions

Need help? Contact us

What is Victron Energy's Smart BMS CL 12-100?

Victron Energy's Smart BMS CL 12-100 is an all-in-one battery management system (BMS). It is specifically designed for Victron Smart lithium batteries (12.8 V) and 12 V systems equipped with an alternator, particularly in vehicles and boats. Its primary function is to protect and monitor each individual battery cell.

Which type of battery is this BMS designed for?

This BMS is specifically designed for Victron Smart 12.8 V lithium batteries. It provides protection and monitoring for each individual cell within these batteries.

How many Victron Smart 12.8V lithium batteries can be connected to this BMS?

Up to 20 Victron Smart 12.8 V lithium batteries can be connected in a single system managed by this BMS.

What is the maximum energy storage capacity that this BMS can manage in a 12V system?

In a 12 V system, the Smart BMS CL 12-100 can manage a maximum energy storage capacity of 84 kWh by connecting up to 20 batteries.

What is the primary function of the Alternator/Starter Batt+ port?

The Alternator/Starter Batt+ port provides current limiting and unidirectional current flow from the alternator to the lithium battery. This allows safe connection of any 12 V alternator (and starter battery) to the lithium battery while protecting the alternator from overload and the lithium battery from excessive charging currents.

How does the Smart BMS CL 12-100 protect the alternator?

The Smart BMS CL 12-100 protects the alternator by electronically limiting the input current on the Alternator/Starter Batt+ port to approximately 90% of the fuse rating. For example, with a 100 A fuse, the input current is limited to about 90 A. This limitation prevents the alternator from overheating and failing during prolonged operation at full power.

Can current flow from the lithium battery to the starter battery?

No, current flow is unidirectional. The Smart BMS CL 12-100 prevents current from flowing from the lithium battery to the starter battery, protecting the lithium battery from deep discharge.

What are the charge or discharge cutoff conditions managed by the BMS?

The BMS monitors and protects each individual battery cell. It will disconnect the alternator, charging sources, or DC loads in the following cases:

Low or high battery cell voltageExcessive temperature

What is the pre-alarm output used for?

The pre-alarm output can be used to activate a relay, an LED, or an audible alarm. It emits a warning signal before the BMS disconnects the batteries from the system in case of imminent low cell voltage. The alarm is triggered with a minimum delay of 30 seconds before the load-disconnect output is deactivated.

What is the IP rating of this Smart BMS?

The Smart BMS CL 12-100 features electronic protection rated IP65. This means it is protected against dust ingress and low-pressure water jets from any direction.

What are the dimensions and weight of the Smart BMS CL 12-100?

The dimensions of the Smart BMS CL 12-100 are 65 x 120 x 224 mm (height x width x depth). Its weight is 1.6 kg.

How can I monitor and configure the Smart BMS CL 12-100?

Monitoring, initial configuration, and diagnostics for the BMS are performed via Bluetooth using the VictronConnect application. This app allows real-time viewing of key parameters.

What is the "Instant Readout" feature in the VictronConnect application?

Instant Readout is a feature in the VictronConnect application that allows real-time reading of the most important BMS values without needing to connect directly to the BMS. This simplifies quick diagnostics and provides better range than standard Bluetooth connections.

Is the Smart BMS CL 12-100 compatible with all 12 V alternators?

Yes, it is designed to be safely connected to any 12 V alternator, thanks to its dedicated input which provides current limiting and protection against alternator overload.

Which type of electrical systems is this BMS primarily designed for?

This BMS is specifically designed for 12 V systems equipped with an alternator, such as those found in vehicles and boats.
