A complete Energy Management System
Not only a BMS… It is a comprehensive “Energy Management System” TAO BMS is unique on the market by the level of protection it provides and a number of features designed to maximise battery life.
BMS comparison chart (v2.02)
As each manufacturer only puts forward what they think will make you buy their product, it is very difficult to make a comparison based on a set of criteria. You can download a BMS comparison chart with more than 100 criteria grouped in 17 sections. There are currently 4 BMS and more will be added as we get input from manufacturer and users.
CANbus setup for Victron products
To manage your installation and your energy, the TAO BMS can communicate with many equipment using the CANbus protocol. A new set of instruction has been released to explain in details how to connect and configure the different equipment to integrate the TAO BMS with Victron products.
Let your BMS manage the chargers
Keeping a lithium battery full all the time will reduces its lifespan. After 10 years a battery will loose 17% of its capacity if its average state of charge is 50%, and it will loose 28% of its capacity if it is full most of the time (*).
TAO BMS can control the chargers to stop the charge at a set SOC and restart them when the SOC gets low.
New latching relay driver (LRD)
Latching (bi-stable) relays have the great advantage to maintain their contact position indefinitely without any power being sent to the coil. They save a lot of energy compared to standard contactors that can consume up to 0.4 A to maintain their contacts closed (10 Ah per day / 300 Ah per month). But they need to be commanded by pulses…
How the BMS controls its environment
See how the TAO BMS protects your lithium DC installation and takes care of your safety. Learn how to program its powerful features in order to control any electrical equipment.
How to build a lithium battery and connect the TAO BMS
This is a step-by-step video on how to build a lithium battery. It explains how to connect the TAO BMS to the lithium cells. And most importantly, how validate that the BMS detects faults.
Why temperature and SOC of lithium cells are important
Temperature and SOC are important parameter that influences the aging of a lithium battery. at 35°C a lithium cell ages twice as fast as it does at 15°C. So if the battery’s useful life is 15 years at 15°C, it will be 7.5 years at 35°C. after 10 years a battery will loose 17% of its capacity if its average…
What is pre-charge and how it works…
When power is first applied to a capacitive load (like inverters and chargers), a large inrush current is induced. This current creates an arc between the relay contacts… that are severely damaged. For that reason capacitive loads need to be pre-charged with a controlled current. TAO BMS can do that for you as a standard feature… What is the risk…
How to charge lithium and lead-acid batteries with an alternator
When installing a lithium battery on a boat or a camping car you need to decide if and how the alternator will charge it at the same time as the starter battery. If not done the right way the alternator could be damaged. In this article I address some key questions you may ask yourself, I point out some challenges…
Choosing the right relay
To get the most out of the BMS and protect your electrical installation you need some heavy duty relays. They open or close the power circuits, can handle high current and are remotely commanded by the BMS. In this article I look at the two main categories of heavy duty relays: contactor or electro-mechanical relay (EMR) solid state relay (SSR)…
New local and “Cloud” dashboard
A WiFi connection to the BMS monitor and a browser are enough to access a new world where you can visualise your battery usage and condition. This information is also available on the Cloud if the BMS monitor is on a WiFi with Internet connection.
