EV fleet workshops are busy places. And, of course, the work usually comes in waves and rushes, most often just as your technicians are relaxing and looking forward to a weekend off. Typical. So, what if you could predict those battery problems earlier? That’s where a comprehensive battery maintenance schedule comes in. And the more […]
Batteries in series vs parallel: what’s the difference? Read More »
Battery imbalance can be a vehicle’s silent killer. It’s a natural process that quietly works away until one of the 12-volt batteries in your 24-volt system gives up before its time, often taking the other one down with it. Battery balancing is the key to stopping it. Here at Rotronics, we’ve made batteries our business.

The odds are that the two 12-volt batteries in your 24-volt system came in pairs. A technician probably installed both on the same day. They’re likely the same brand, and they should be exactly the same spec. But by now, they’re very rarely in the same condition as each other. Here’s what you’re almost certain
What is battery balancing and what does it achieve? Read More »
The battery packs in your EVs are made up of hundreds (and in some cases thousands) of individual cells connected in series. The more cells connected, and the higher the voltage of each cell, the higher the overall pack voltage, which powers the vehicle. However, keeping all those individual cells balanced – meaning each cell
What is passive top balancing and how does it work? Read More »
Electric vehicles (EVs) store chemical energy in their battery packs, which is then converted to electrical power to drive the wheels. These battery packs are complex assemblies of hundreds of individual cells working together. When all these cells are balanced (that is, they all have the same state of charge and state of health), your

Batteries don’t usually fail all of a sudden. They wear out slowly, often without warning, until one day the engine won’t start. Every fleet has dealt with the unexpected non-starter on a tight schedule. But what if you could predict battery lifespan more accurately, get replacements lined up in advance and significantly cut downtime? How
How many years should a vehicle battery last? Read More »
Vehicle battery problems often aren’t just about low charge. Most of the time, something inside the battery is wearing out or failing. That’s why knowing how battery testing works helps you spot problems faster, especially when you already know your vehicles and how they’re used. This guide explains the main types of battery testing, what each one
