If it comes to powering RVs, boats, golf cars and electric vehicles, or providing storage for solar energy systems, RELiON’s lithium iron phosphate batteries offer you several benefits over lead-acid batteries. They have more life. They’re lighter weight, and have a greater capacity. They need no maintenance and can be mounted in almost any way. They also bill quicker, and do not call for a complete charge before they may be used or stored.
Molicel Battery batteries may be safely discharged over a broad array of temperatures, usually out of –20°C into 60°C, making them practical for usage in climatic conditions confronted by many possibly cold temperature applications such as RVs and off-grid solar. In reality, lithium ion batteries have far greater functionality at colder temperatures than lead-acid batteries. At 0°C, by way of instance, a lead-acid battery capacity is decreased by around 50%, though a lithium iron phosphate battery endures just a 10% reduction at precisely the exact same temperature.
The Challenge of Low-Temperature Lithium Charging
If it comes to recharging lithium ion batteries, nevertheless, there is one hard and fast principle: to prevent irreversible damage to the battery, do not charge them as soon as the temperature drops below freezing (0°C or even 32°F) without decreasing the charge current. Unless your battery management system (BMS) communicates with your charger, along with the charger has the power to respond to the information supplied, this is sometimes hard to do.
What is the motive for this rule?
When charging in above-freezing temperatures, then the lithium ions within the battery have been soaked up as in a nozzle from the porous graphite which makes the anode, the negative terminal of the battery life. Below freezing, but the lithium ions are not economically captured by the anode. Rather, many lithium ion ions coating the surface of the anode, a procedure called lithium ion , so there is less lithium ion readily available to induce the flow of electricity along with the battery’s power drops. Charging below 0°C for an inappropriate rate rate, also results in the battery to be mechanically stable and more prone to sudden collapse.
The harm to the battery when charging colder temperatures is due to the charging speed. Charging at a significantly slower rate can lower the harm, but that is seldom a practical alternative. Typically, if a lithium ion is billed below freezing once, it is going to be permanently damaged and have to be safely discarded or recycled.
In below-freezing states, with no BMS communication to a charger that’s programmed to lessen present when required, the only alternative is to warm the batteries to over freezing before charging, either by bringing them into a warmer environment or simply by wrapping them into a thermal blanket or putting a little heater close to the bolts, ideally using a thermometer to monitor the temperature during charging. It is not the most convenient procedure.
A New Lithium-Ion Battery System for Low-Temperature Charging
To fix the issue of charging and also to create lithium ion batteries safer and more functional for low-temperature usage, RELiON has generated a new collection of lithium iron phosphate batteries which can control at temperatures down to -20°C (-4°F). The machine features proprietary technologies that brings power from the charger , requiring no additional parts.
The full procedure of charging and warming is completely easy for the consumer. Only plug the battery into the normal lithium-ion charger as well as the inner heating and tracking system deals with the rest.
As it takes some time to warm the tissues, the charging procedure in below freezing temperatures will require somewhat longer. By way of instance, using all the low-temperature RELiON RB100-LT 100Ah battery, it requires approximately an hour to heat from -20°C into +5°C before charging starts. More than a smaller temperature range, heating into a secure charging temperature occurs proportionately faster.
RELiON’s low-temperature series look and function just as with our other batteries, together with exactly the exact same power and functionality. They have exactly the identical charge time in above-freezing temperatures. Additionally they have the very same dimensions, configuration, and connectivity of its own regular counterparts, so they’re drop in replacements from software that currently use RELiON batteries. And they are perfect upgrades for people who are still utilizing lead-acid batteries in low-temperature environments.
An Ideal Lithium Battery Solution for Low-Temperature Applications
Together with RELiON’s RB100-LT LiFePO4 battery, users that occasionally face below-freezing temperatures are now able to enjoy the many advantages of a lithium ion battery without needing to be concerned about heating the battery before charging. The RB100-LT features exactly the exact same dimensions and functionality since RELiON’s RB100, but could safely control when temperatures fall as low as -20°C employing a normal charger. It is an perfect option for use in RVs, off-grid solar, electrical vehicles, and in almost any program where charging in colder temperatures is essential. More versions at the Low Temperature series will soon be available shortly.
