OUR TECHNICAL SERVICES

What We Handle

Our battery services cover diagnosis, testing and troubleshooting across the battery, BMS, cells and inverter communication system.

BMS Diagnosis

Diagnosis and troubleshooting of battery management system faults and protection conditions.

  • BMS fault diagnosis
  • Protection fault investigation
  • BMS status assessment
  • BMS replacement where applicable

Cell & Battery Testing

Testing of battery cells and packs to identify imbalance, weak cells and other electrical issues.

  • Individual cell testing
  • Cell imbalance checks
  • Faulty cell identification
  • Cell replacement where appropriate

Charging & Electrical Faults

Investigation of charging, discharging and battery protection faults.

  • Charging fault diagnosis
  • Discharging problems
  • Over-voltage / under-voltage
  • Temperature protection faults

Communication Troubleshooting

Diagnosis of communication problems between lithium batteries and compatible inverters.

  • CAN Bus troubleshooting
  • RS485 communication
  • Protocol investigation
  • Inverter-to-battery communication
BMS DIAGNOSIS

Battery Management System Troubleshooting

The Battery Management System helps monitor and protect lithium battery cells. When a BMS develops a fault, the battery may stop charging, shut down or display incorrect battery information.

We investigate the battery condition, protection status, cell readings and communication before recommending repair or replacement.

CELL TESTING

Lithium Cell Testing & Battery Assessment

A lithium battery can experience reduced performance when one or more cells become weak or unbalanced.

During assessment, we examine relevant battery and cell parameters to help identify the source of the problem.

  • Individual cell or cell-group voltage
  • Battery pack voltage
  • Cell balance and condition
  • BMS readings and protection status
  • Charging and discharge behaviour

Cell replacement depends on the battery design, condition and availability of compatible cells.

CAN BUS & RS485

Battery & Inverter Communication

Lithium batteries and hybrid inverters may rely on communication between the BMS and inverter to exchange battery information such as voltage, current and state of charge.

Important Battery Safety

Lithium batteries contain significant stored energy and can present electrical, thermal and fire hazards when incorrectly handled. Battery inspection and repair should be carried out using suitable equipment, procedures and protective measures.

Do not short-circuit, puncture, modify or attempt cell-level repairs without the appropriate technical knowledge and equipment.
