If you manage an electric vehicle fleet, you’ll know how disruptive battery issues can be.
A flat or failing battery doesn’t just sideline a vehicle; it can throw off your schedule, your drivers and your bottom line.
Good battery management puts you back in control. With the right tools and approach, you’ll keep your vehicles on the road for longer, reduce avoidable failures and maximise the value of every battery in your fleet.
Why battery management matters for fleets
Batteries are critical components of every modern vehicle, and in EVs, they’re also the most expensive component to replace (between £5,000 and £20,000, in most cases). When they fail, the whole vehicle is out of action.
Ironically, EVs still depend on the same type of 12-volt batteries used in ICE and hybrid vehicles. An electric vehicle won’t start if the 12-volt battery is dead because it powers the car’s control systems and safety checks that need to run before the main high-voltage (HV) battery can turn on. Without that initial power, the EV can’t ‘boot up’, even if the main battery is fully charged.
Most EVs come with built-in battery management systems (BMSs). These are for the car. They’re designed to protect the battery during driving and charging. The ‘battery management’ we’re discussing on this page is about you managing the health of your fleet.
And that’s where Rotronics’ solutions come in. Our equipment works in-tandem with your vehicles’ in-built systems to give you full visibility across your battery assets, so you’re better equipped to maximise your ROI and keep your electric fleet operating at peak efficiency.
Proactive battery maintenance for EV fleets
Batteries degrade slowly. Without testing, that degradation might go unnoticed until the vehicle fails to start or breaks down on the road. That’s both inconvenient and expensive.
Our diagnostic tools and software make proactive maintenance easy. You can test, monitor and report on battery health across your entire fleet, spotting weak batteries before they let you down.
For example, the GRX-5100 performs module-level diagnostics and balancing on high-voltage EV battery packs. It identifies performance issues at the module level, helps you safely charge or discharge during maintenance, and gives you the insight needed to prevent premature failure.
Also, let’s face facts. Battery replacements are expensive, especially in electric vehicles. Even though EVs tend to come with relatively long warranties for their advanced battery systems, getting as much service life out of every battery you buy as possible makes sense. Plus, improper maintenance could void your warranties. With proper maintenance, you reduce the risk of early failure and avoid replacing batteries that still have useful life left in them.
While the GRX-5100 is vital for the high-voltage battery pack, tools like the xLVS-9000 are ideal for monitoring 12-volt systems, which are still essential in EVs. The system delivers EV-specific diagnostics to spot voltage trends, detect weakening batteries, and provide early warning before failure strikes. For EV fleets, it’s a game-changer.
Real-world benefits for fleet operators
Battery management delivers different benefits depending on your fleet size, structure and business model. But the outcomes are always the same: lower cost, higher efficiency, and reduced downtime. Some of the benefits include:
- Improved uptime – fewer battery-related breakdowns means fewer vehicles off the road.
- Lower maintenance costs – spot faults early, fix them fast and extend battery lifespan.
- Operational confidence – reduce the uncertainty around battery condition, especially in cold or high-demand conditions.
- Data-driven decisions – make better calls on battery replacements and servicing with real-world performance data.
Managing your batteries properly rests on having the right tools. But it’s also about embedding good habits into your fleet maintenance routines, including:
- Regular battery testing
- Accurate battery health and trend reporting
- Using correct and well-maintained chargers
- Conditioning batteries in hot or cold weather
- Avoiding over-reliance on fast charging
- Partnering with battery specialists for support
